Pip3 abort signal on startup

catalinahomebrewpython

I've just upgraded to macOS Catalina, I've used brew install dpkg, and homebrew decided it was time to run brew cleanup.

After running it, I've not been able to run pip3 anymore.

Tried running brew doctor and brew reinstall python3, but none helped.

Running pip3 outputs this:

[1] 26346 abort pip3

That problem is caused by asn1crypto.
You could try:

rm -rf /usr/local/lib/python3.7/site-packages/asn1crypto*

Which will uninstall asn1crypto.

MacOS – Why does the brew installation not work

"Command not found" indicates that the brew binary isn't on one of the directories listed in your PATH environment variable. To check what your path is currently, run echo $PATH. By default, brew installs to /usr/local/bin. To set the path permanently, you should edit your ~/.bashrc file to contain the line export PATH="/usr/local/bin:$PATH".

Can’t re-install homebrew

Short term answer, try this command to see if your brew installation worked:

/usr/local/bin/brew doctor

It seems that your bash environment may not be looking in the /usr/local/bin for executibles (which means you have to write the full path rather than just the name of the command). The solution may be just resourcing your conf files, which can be roughly done by closing your terminal and opening a new one. Otherwise, you'll want to add a line to your ~/.bash_profile. I think resourcing will do the trick though.

So after confirming the success with the first doctor, try quitting your terminal application and starting fresh, then your original usage of brew should work. If it doesn't try:

echo $PATH

and report back the results.
