If you try to run sudo -H pip3 install --upgrade pip3   you will get the following error  WARNING  You are using pip version 19 2 3  however version 21 0 1 is available  You should consider upgrading via the  pip install --upgrade pip  command   but if you upgrade using the suggested command  pip install --upgrade pip  then  the legacy pip will be upgraded  so what I did is the following  which pip3  and I located my pip3 installation  just in case the following command wouldn t upgrade the legacy pip  Then i changed to that directory and upgraded pip3 using the following commands   your directory could be different  cd  Library Frameworks Python framework Versions 3 8 bin sudo -H pip3 install --upgrade pip  after this  pip --version  will still show the legacy version  while pip3 --version  will show pip 21 0 1

First decide which pip you want to upgrade  i e  just pip or pip3  Mostly it ll be pip3 because pip is used by the system  so I won t recommend upgrading pip  The difference between pip and pip3 is that  NOTE  I m referring to PIP that is at the BEGINNING of the command line    pip is used by python version 2  i e  python2  and  pip3 is used by python version 3  i e  python3  For upgrading pip3    This will upgrade python3 pip  pip3 install --upgrade pip  For upgrading pip    This will upgrade python2 pip  pip install --upgrade pip  This will upgrade your existing pip to the latest version

The Problem  You use pip  the Python 2 one   Now you want to upgrade pip  the Python 3 one   After that  pip is the Python 3 one   The solution  Use pip2 and pip3  This way it is explicit   If you want to use pip  just check where it is  which pip  and change the link  For example     which pip  usr local bin pip    pip --version pip 9 0 1 from  usr local lib python3 5 dist-packages  python 3 5     which pip2  usr local bin pip2    sudo rm  usr local bin pip   sudo ln -s  usr local bin pip2  usr local bin pip    pip --version pip 9 0 1 from  usr local lib python2 7 dist-packages  python 2 7

You are using pip3 to install flask-script which is associated with python 3 5  However  you are trying to upgrade pip associated with the python 2 7  try running pip3 install --upgrade pip   It might be a good idea to take some time and read about virtual environments in Python  It isn t a best practice to install all of your packages to the base python installation  This would be a good start  http   docs python-guide org en latest dev virtualenvs

If you have 2 versions of Python  eg  2 7 x and 3 6   you need do    add the path of 2 x to system PATH add the path of 3 x to system PATH pip3 install --upgrade pip setuptools wheel   for example  in my  zshrc file   export PATH  usr local Cellar python 2 2 7 15 bin  usr local Cellar python 3 6 5 bin  PATH   You can exec command pip --version and pip3 --version check the pip from the special version  Because if don t add Python path to  PATH  and exec pip3 install --upgrade pip setuptools wheel  your pip will be changed to pip from python3  but the pip should from python2 x
