I wanted to deploy my Python app on Amazon Linux AMI 2015.09.1, which has Python2.7 (default) and pip (6.1.1). Then, I upgraded the pip using the command:
sudo pip install -U pip
However, it seemed broken, and showed the message when I tried to install packages:
I found out that pip remove the previous files located in /usr/bin/, and installed the new one in /usr/local/bin. Thus, I tried to specify the location by using the command:
sudo pip install -U --install-option="--prefix='/usr/bin'" pip
Nevertheless, it still installed the new one in /usr/local/bin. In addition to that, pip could not work well with sudo although it successfully installed. The error message :
sudo: pip2.7: command not found
Is there a way to properly manage pip?
