Installing pip on macOS Sierra

Question

I've been trying to install pip on macOS sierra via brew, but every time it completes without installing the binaries in /usr/local/Cellar/python/2.7.13/bin.

I've tried:

MacBook-Pro ➜ brew reinstall python

then:

MacBook-Pro ➜  ~ which pip
pip not found

I found the path to python, which is /usr/local/Cellar/python/2.7.13/bin but no binary for pip there.

I also tried the easy_install approach:

MacBook-Pro ➜ sudo easy_install pip
Traceback (most recent call last):
  File "/usr/bin/easy_install-2.7", line 11, in <module>
    load_entry_point('setuptools==18.5', 'console_scripts', 'easy_install')()
  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 352, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 2307, in load_entry_point
    return ep.load()
  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 2021, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/setuptools/__init__.py", line 12, in <module>

    from .dist import _get_unpatched

    packaging = pkg_resources.packaging
AttributeError: 'module' object has no attribute 'packaging'

UPDATE:

When I run brew postinstall python I am getting the following error:

MacBook-Pro ➜  ~ brew postinstall python

==> /usr/local/Cellar/python/2.7.13/bin/python -s setup.py --no-user-cfg install --force --verbose --single-version-externally-managed --rec

Answer 1

For Mac OS Sierra, cannot install pip via easy_install since there is a problem with TLS Version, Installed Open-SSL version won't support TLS 1.2

So install pip using curl as follows,

curl https://bootstrap.pypa.io/get-pip.py | sudo python

Answer 2

You just need to install pip which is not automatically installed in macOS Sierra.

Run sudo easy_install pip
