Re: python -m pip install and pip install
When you upgrade pip, you have to write: python -m pip install --upgrade pip When you install or upgrade anything else, you can write "pip install". You can't upgrade pip using "pip install --upgrade pip". אורי u...@speedy.net On Mon, Oct 7, 2019 at 2:21 PM Hongyi Zhao wrote: > Hi, > > What's the diff: > > python -m pip install mod > and > pip install mod > -- > https://mail.python.org/mailman/listinfo/python-list > -- https://mail.python.org/mailman/listinfo/python-list

So the scripts will just work fine if you simply use ~import pip~ and work with it. Suppose you were writing bash scripts around python programs. Then what will be the behaviour of, pip2 install mod under a python3 environment. Similarly, there may be other commands specific to python2 and python3. All of them work flawlessly if you just replace python2 with python3. -- Regards, Pankaj Jangid -- https://mail.python.org/mailman/listinfo/python-list

And nowadays, the pyenv + vurtualenv + pip + pipenv is the suggested env management method for python. In this way, the pipenv will solve the version dependence of the underlying tool chain and corresponding used packages/modules. > > > > > It isn't a deal breaker, but preferred: one less moving part. > > > > Cheers, > > Cameron Simpson > > > > -- > Hongsheng Zhao > Institute of Semiconductors, Chinese Academy of Sciences > GnuPG DSA: 0xD108493 -- Hongsheng Zhao Institute of Semiconductors, Chinese Academy of Sciences GnuPG DSA: 0xD108493 -- https://mail.python.org/mailman/listinfo/python-list

If so, why not just: pip2 install mod and using: pip3 install mod Because of the slight disconnect between "pip2" and "python2", etc. Do you _know_ they both use the same Python install? With "pythonX -m pip" you're using the same python executable which will be accessing what you just installed. It isn't a deal breaker, but preferred: one less moving part.
