Error running 'pip install': "ImportError: No module named pip" [duplicate]

With macOS v10.15 (Catalina) and Homebrew 2.1.6, I was getting this error with Python 3.7. I just needed to run:

python3 -m ensurepip 

Now python3 -m pip works for me.

My solution for an Ubuntu machine:

For Python 3

sudo apt install python3-pip 

For Python 2

sudo apt install python-pip 

On Mac, using Homebrew (executable brew) is a better option as apt-get is not available.

Command:

brew install python 

In case you have both Python 2 and Python 3 installed on the machine:

python2.7 -m ensurepip --default-pip 

simply should solve the issue.

If instead you are missing pip from Python 3 then simply change python2.7 to python3 in the command above.

For Windows:

python -m ensurepip 

After activating your environment. Example: venv

(venv) PS D:\your path> d:\your path\venv\scripts\python.exe -m pip install --upgrade pip 

Sample of a result:

Collecting pip Using cached pip-21.3-py3-none-any.whl (1.7 MB) Installing collected packages: pip Attempting uninstall: pip Found existing installation: pip 20.1.1 Uninstalling pip-20.1.1: Successfully uninstalled pip-20.1.1 Successfully installed pip-21.3 

After installing ez_setup, you should have easy_install available. To install pip just do:

easy_install pip 

Run

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py 

Then run the following command in the folder where you downloaded: get-pip.py

python get-pip.py 

Try to install pip through Python:

Please go to: https://pip.pypa.io/en/stable/installation/

and download get-pip.py, and then run:

python get-pip.py 

On some kind of Linux, like distributions based on Debian, you might want to consider updating your 'apt-get' first, in case you are installing python-pip through it.

sudo apt-get update 

This might help apt-get to update its indexes and locate the python-pip package. After this, you might install pip like this:

sudo apt-get install python-pip (Python 2) sudo apt-get install python3-pip (Python 3) 

I encountered the same error with Python 3.8.6 on macOS v11 (Big Sur).

Whether I used pip or pip3, I'd get this error:

 File "/Users/marcelloromani/dev/<repository>/venv/bin/pip", line 5, in <module> from pip._internal.cli.main import main ModuleNotFoundError: No module named 'pip' 

It turns out my virtualenv was out of date. This fixed the issue for me:

1. Remove the old virtualenv

   deactivate rm -rf venv 

2. Initialise a new virtualenv

   virtualenv venv . venv/bin/activate 

3. Install the new requirements then worked:

   pip install -r src/requirements.txt 

If you get "No module named pip" in Ubuntu, try this:

python3 -m pip --version 

Output:

/usr/bin/python3: No module named pip 

And:

sudo apt-get install python3-pip 

It worked for me.

After successful installation, validate using

python3 -m pip --version 

To upgrade to the latest pip version

python3 -m pip install --upgrade pip 

I ran into this same issue when I attempted to install the Nova client (as root).

python setup.py install 

Output:

running install /usr/bin/python: No module named pip error: /usr/bin/python -m pip.__init__ install 'pbr>=0.5.21,<1.0' 'iso8601>=0.1.4' 'PrettyTable>=0.6,<0.8' 'requests>=1.1' 'simplejson>=2.0.9' 'six' 'Babel>=0.9.6' returned 1 

I use Homebrew, so I worked around the issue with sudo easy_install pip.

brew search pip 

Output:

aespipe brew-pip lesspipe pipebench pipemeter spiped pipeviewer If you meant "pip" precisely: Homebrew provides pip via: `brew install python`. However you will then have two Pythons installed on your Mac, so alternatively you can: sudo easy_install pip spencers-macbook-pro:python-novaclient 

And:

sudo easy_install pip 

The commands should be similar if you use MacPorts.

Use:

python -m ensurepip --user 

This if your Mac is not above macOS v11 (Big Sur) and you installed Python 3. I did this and I don't have any problems now. Back to the legacy version of 2.7 I guess.

Try to re-install the pip use curl command to download the get-pip.py file:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py python get-pip.py 

if curl is not working then open this link : get-pip.py

create a get-pip.py file in your directory copy the code from this link and put it in the get-pip.py file and save the file in the same directory. then run the command

python get-pip.py 

Python3

curl -sS https://bootstrap.pypa.io/get-pip.py | python3 python3 -m pip install --upgrade pip 

Just replace the python version you want in the above commands

For python 3.11 specific install

curl -sS https://bootstrap.pypa.io/get-pip.py | python3.11 python3.11 -m pip install --upgrade pip 

For python 3.10 specific install

curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10 python3.10 -m pip install --upgrade pip 

For python2.7

curl -sS https://bootstrap.pypa.io/pip/2.7/get-pip.py | python2.7 python2.7 -m pip install --upgrade pip 

It is very likely that the pip package was unsuccessfully updated. You need to remove and recreate the virtual environment.

Deactivate and remove the virtual environment:

deactivate rm -rf [virtual_environment_name] 

Create a new one

python -m venv venv_name 

Activate it

source ./venv_name/Scripts/activate 

Install the package you want:

pip install [package_name] 

Download:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py 

Then install pip:

py get-pip.py 

Then install any module, such as Biopython:

py -m pip install biopython 

I know this thread is old, but I just solved the problem for myself on OS X differently than described here.

Basically I reinstalled Python 2.7 through brew, and it comes with pip.

Install Xcode if not already:

xcode-select –install 

Install Brew as described here:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 

Then install Python through Brew:

brew install python 

And you're done. In my case I just needed to install pyserial.

pip install pyserial 

I think none of the previous answers can fix your problem.

I was also confused by this problem once. You should manually install pip following the official guide pip installation (which currently involves running a single get-pip.py Python script).

After that, just pip install <your package>. The error will be gone.

I encountered the issue ModuleNotFoundError: No module named 'pip' when I created a new Python 3 virtual environment using the command

python3 -m venv ~/venv/ontology ## << note: "python3" (problematic) 

which is a command often suggested (here, elsewhere). When I entered that venv, pip was nowhere to be found.

In the interim, since first using that command to create Python virtual environments, my system Python had upgraded (Arch Linux system updates) from Python 3.7.4 to Python 3.9.2.

The solution is to use the command

python -m venv <your_venv> ## e.g. python -m ~/venv/ontology 

When I did that (python -m ... not python3 -m ...), that venv now contained pip ...

To upgrade pip within that venv, use

<your_venv_path>/bin/python -m pip install --upgrade pip ## e.g. ## /home/victoria/venv/ontology/bin/python -m pip install --upgrade pip 

I downloaded pip binaries from here and it resolved the issue.

I am using Debian, but this solution can also be applied for Ubuntu.

1. Usually, pip comes with python by default, in order to check if pip is installed in your system run.

python -m pip --version 

2. If pip is not there, install it using Aptitude Linux Package Manager,

# For Python 2 sudo apt install python-pip # For Python 3 sudo apt install python3-venv python3-pip 

3. I wouldn't use the get-pip.py script in Debian/Ubuntu, because in the documentation page mentions the following.

Be cautious if you are using a Python install that is managed by your operating system or another package manager. get-pip.py does not coordinate with those tools, and may leave your system in an inconsistent state.

Sources here and there.

In a terminal, try this:

ls -lA /usr/local/bin | grep pip 

In my case I get:

-rwxr-xr-x 1 root root 284 Сен 13 16:20 pip -rwxr-xr-x 1 root root 204 Окт 27 16:37 pip2 -rwxr-xr-x 1 root root 204 Окт 27 16:37 pip2.7 -rwxr-xr-x 1 root root 292 Сен 13 16:20 pip-3.4 

So pip2 or pip2.7 in my case works, and pip.

Here's a minimal set of instructions for upgrading to Python 3 using MacPorts:

sudo port install py37-pip sudo port select --set pip pip37 sudo port select --set pip3 pip37 pip install numpy, scipy, matplotlib 

I ran some old code and it works again after this upgrade.

I was facing the same error on Windows 11, so the main problem was on executing the pip command without administrator permissions, so open up your terminal with administrator permissions and then execute the pip command again.

I just needed to replace pip with pip3 so I ended up running the command as follows: pip3 install matplotlib

I had a similar problem with virtualenv that had python3.8 while installing dependencies from requirements.txt file. I managed to get it to work by activating the virtualenv and then running the command python -m pip install -r requirements.txt and it worked.

I solved a similar error on Linux by setting PYTHONPATH to the site-packages location. This was after running python get-pip.py --prefix /home/chet/pip.

[chet@rhel1 ~]$ ~/pip/bin/pip -V Traceback (most recent call last): File "/home/chet/pip/bin/pip", line 7, in <module> from pip import main ImportError: No module named pip [chet@rhel1 ~]$ export PYTHONPATH=/home/chet/pip/lib/python2.6/site-packages [chet@rhel1 ~]$ ~/pip/bin/pip -V pip 9.0.1 from /home/chet/pip/lib/python2.6/site-packages (python 2.6) 

I followed the advice on this URL, to rename the python39._pth file. That solved the issue

https://michlstechblog.info/blog/python-install-python-with-pip-on-windows-by-the-embeddable-zip-file/#more-5606

ren python39._pth python39._pth.save 

Tested below for Linux:

You can directly download pip from https://pypi.org/simple/pip/, untar, and use directly with your latest Python installation.

tar -xvf pip-0.2.tar.gz cd pip-0.2 

Check for the contents:

ls 

Output:

docs pip.egg-info pip-log.txt pip.py PKG-INFO regen-docs scripts setup.cfg setup.py tests 

Execute directly:

python pip.py --help 

Output:

Note that the user:password@ is optional and required only if you are behind an authenticated proxy. If you provide [email protected]:port then you will be prompted for a password. --timeout=SECONDS Set the socket timeout (default 15 seconds) 

My Python version is 3.7.3, and this command worked:

python3.7 -m pip install requests

Requests library - for retrieving data from web APIs.

This runs the pip module and asks it to find the requests library on pypi.org (the Python Package Index) and install it in your local system so that it becomes available for you to import.
