If you are getting the following error while installing a pip package, this solution should work for you.
sys.stderr.write(f"ERROR: {exc}")
Solution :
A) If you are installing a pip package with default python (2.7) and getting above error, run following command
curl https://bootstrap.pypa.io/2.7/get-pip.py --output get-pip.py
python get-pip.py
B) If you are installing a pip package with python3 and you are installing a package using pip3 command, run following command
curl https://bootstrap.pypa.io/3.5/get-pip.py --output get-pip.py
python3 get-pip.py
Change the python version in url, it depends on your system's python version.
C) If you are installing a pip package in a virtual environment with python3.5, run following command in your virtual environment
Command python or python3 both should work same in the virtual env.
curl https://bootstrap.pypa.io/3.5/get-pip.py --output get-pip.py
python3 get-pip.py
