"-bash: twine: command not found" when attempting to upload to PyPi

I am attempting to publish a package to PyPi using twine. Running twine upload dist/* in the project folder gives -bash: twine: command not found.

I am using Python 3.7.7 on MacOS Mojave. I have run pip install twine successfully, and running pip3 install twine tells me that twine is already installed.

I have seen other answers suggesting that I add the directory where twine is installed to the $PATH in my ~/.bash_profile. Running pip show -f twine gives me:

Name: twine

followed by a list of files.

I have added /Users/Username/Library/Python/3.7/lib/python/site-packages/bin, /Users/Username/Library/Python/3.7/lib/python/site-packages, and /Users/Username/Library/Python/3.7/lib/bin to the $PATH, as per various answers, and the error persists.

Solution

I added /Users/Username/Library/Python/3.7/lib/python/bin and /Users/Username/Library/Python/3.7/lib/bin to the $PATH, and that appears to have fixed the problem.
