Receiving an error attempting to pip install streamlit

Question

Windows 10. Using latest version of pip. python 3.8.3.

Getting this error.

I tried installing through pycharm and got the same error.

The error you want to look up to is RuntimeError: Broken toolchain: cannot link a simple C program. Checkout here: stackoverflow.com/questions/52265584/… and here: github.com/numpy/numpy/issues/9783 — Aviel Fedida

The easiest way around this, other than mucking about trying to install a C compiler on Windows just for one package, is to install a pre-compiled version of NumPy from Christoph Gohlke's excellent Unofficial Windows Binaries for Python Extension Packages site. I'd recommend the MKL (Intel's Math Kernel Library) version, but he has completely open-source "vanilla" versions as well.

Simply download the .whl file corresponding to your OS and Python version, then run

pip install wheel_filename.whl

from whichever directory you downloaded it to and you'll be all set. If any other pip install commands break on trying to compile a Python package, check Gohlke's repo first!

Thanks. I installed the streamlit and and its required packages via anaconda and copied them into the python 3.8 folder. Not sure if that's a viable long-term / workable approach

download the appropriate version from https://pypi.org/simple/streamlit/

I am using streamlit 0.62.1 along with python 3.8.5 and it works fine.

I tried the latest version of streamlit 0.76.0 but gives error on installation

pip install C:\downloads\streamlit-0.62.1-py2.py3-none-any.whl
