I've tried to install pandas using pip but several warnings and an one error appears.

Here is the command that I used

pip install pandas

I've received several warning messages like this:

When, finally, the error message appears

My python version is Python 2.7.6 and my ubuntu version is 16.04

What is the cause of the error?

  • you pandas version is not compatible with the python version you are using. Try to upgrade your python to 3.X or find a pandas version suited for your current python version. Commented Feb 19, 2018 at 17:20

I can't reproduce your error. I use docker to run a container to simulate your issue. More specifically, I ran docker run -it --rm ubuntu:16.04 bash and inside the container:

1 apt-get update 2 apt-get install wget 3 wget https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz 4 ls 5 tar xzf Python-2.7.6.tgz 6 ls 7 cd Python-2.7.6 8 ls 9 ./configure 10 apt-get install build-essential checkinstall 11 apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev 12 ./configure 13 python 14 make 15 make install 16 python 17 pip 18 curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py" 19 apt-get install curl 20 curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py" 21 ls 22 python get-pip.py 23 pip 24 pip install pandas 25 history

So probably you installed system dependencies (e.g. gcc), python, or pip in a different way. I followed https://askubuntu.com/questions/443048/python-2-7-6-on-ubuntu-12-04-how-to. How did you install your stuff?
