为不同版本的python升级pip

Question

I have two versions of python installed on my computer (3.6 and 3.7). Just upgraded pip to the latest version (19.0.1) using the command python -m pip install --upgrade pip however i think it only upgraded the pip for python version 3.6. When attempting to install a package specifically for python version 3.7 with the following command pip3.7 install scipy i got the message saying You are using pip version 18.1, however version 19.0.1 is available. Clearly only the pip for version 3.6 was upgraded. I cannot figure out a command to upgrade 3.7 pip as well. I tried the following:

python -m pip3.7 install --upgrade pip

This did not work (Trying to use the logic of how packages are handled for different versions of python). Could not find a question that addressed this specific issue. Any help would be greatly appreciated.

Answer 1

Use the python 3.7 interpreter to run the command:

python3.7 -m pip install --upgrade pip

Or use the pip3.7 binary directly:

pip3.7 install --upgrade pip

Answer 2

export LD_LIBRARY_PATH=/usr/lib64

activate pip3

Answer 3

I ran into the same problem. If you have Microsoft Visual also installed the best command to use is

    py -m pip install --upgrade pip --user

I used that command, and it worked like a charm.
