How to install pip packages to specific Python version?

Question

I have Python 3.7 and Python 3.6. How to I chose to which version of Python I want my PIP packages?

Answer 1

On Linux the @jwodder answer is fine, but on Windows use the Python Launcher, which is normally installed by default. You specify the version of Python to launch as -XY , eg:

py -3.6 -m pip install ...

Answer 2

You use the version of pip that corresponds to the desired Python version. The most universally effective way is to run pythonX.Y -m pip install ... , where XY is replaced with the Python version number, though running just pipX.Y install ... may also work under some circumstances.

Answer 3

使用python -m pip其中 python 是您要安装到的 python 版本

Answer 4

I would suggest to use the newer and (now) recommended way of installing Python application dependencies: pipenv . You can consider pipenv to be the better pip ( pip + virtualenv handling + proper depedency management). Using pipenv you create a Pipfile and you can specify the exact python_version you want to use in that file. Since I started using pipenv in my projects most headaches I had previously with Python dependency and version management are gone.
