pip 安装不起作用，找不到分发

Question

I am trying to install Pip and anaconda.

In my mac I have both python 2 as well as python 3.

When I try to easy_install pip I get the error [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/test-easy-install-14341.write-test'

So I tried to do a pip install

I GOT

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 3241, in <module>

    dists = ws.resolve(reqs, Environment())

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pip==19.3.1' distribution was not found and is required by the application

Also I cannot install Anaconda, maybe because of this problem

PS. I have used homebrew to install python.

Have anyone solved it?

Answer 1

One of the problem is that from now on we to use pip3 instead of just pip . Another problem is that the open ~/.zshrc file need to be updated with the same open ~/.bash_profile instruction from anaconda.

IN CONCLUSION

I think that for installing pip packages you need to use the pip3 command or you could write an alias file where you substitute pip with pip3.

Then for actually using conda I followed this article so that it overrun the zhs of the mac config.
