如何将pip升级到pip3并从python 2.7切换到3

Question

so I have a MacBook Air running 11.2.1 Big Sur

pip --version

returns this output:

pip 20.2.1 from /Library/Python/2.7/site-packages/pip-20.2.1-py2.7.egg/pip (python 2.7)

when I type python into the terminal, it automatically loads python 2.7, and python3 loads python 3.8.2 like its supposed to

I want to install PyQT5 and this version of pip isn't letting me do that, I want to upgrade pip to pip3 and replace python 2 with python 3 in the process.

Can you guys help me upgrade my python and pip? I don't mind losing python or pip 2 completely.

Answer 1

for macOs brew install pyhton3

Answer 2

Use python3 interpreter to run the command:

python3 -m pip install --upgrade --force pip

The -m calls the __main__.py module of a specified package.

Use pip3 binary directly:

pip3 install --upgrade --force pip

Valid with: pip -V
