vim is broken after a brew upgrade

Question

I tried to upgrade vim using brew upgrade vim and I cannot make vim works anymore since then.

The error message I get is:

dyld: Library not loaded: /usr/local/opt/python/Frameworks/Python.framework/Versions/3.7/Python
  Referenced from: /usr/local/bin/vim
  Reason: image not found
Abort trap: 6

I tried the following:

brew uninstall vim
brew cleanup
brew install vim

but it did not solve the problem at all.

I also completely removed the content of the .vimrc file where some plugings were installed to check for python syntax. Again, that did not change the error message I get.

I do not know what I am missing, and I would like to understand where the problem comes from.

Answer 1

I have fixed the issue and it is kinda hack but whatever it works now :) My error was following:

dyld: Library not loaded: /usr/local/opt/python/Frameworks/Python.framework/Versions/3.7/Python
  Referenced from: /usr/local/bin/vim
  Reason: image not found

The issue was actually not having version 3.7 located on the path: /usr/local/opt/python/Frameworks/Python.framework/Versions/3.7/ However I had 3.8 folder there...

So I just made a sym link by doing

$ ln -s 3.8 3.7

And yes I am aware that the fix should be changing reference from /usr/local/bin/vim to use 3.8 instead of 3.7 but this works also and I did not have the time to dive in it further.

I was facing the similar error but with different library :

dyld: Library not loaded: /usr/local/opt/lua/lib/liblua.5.3.dylib   Referenced from: /usr/local/Cellar/macvim/....../MacOS/Vim   Reason: image not found Abort trap: 6

and the workaround give above to add symlink to the available version in the /usr/local/opt/lua/lib directory helped.

Below is what I did:

cd /usr/local/opt/lua/lib

$ ls

liblua.5.4.2.dylib  liblua.5.4.dylib    liblua.dylib        liblua5.4.dylib     pkgconfig

Above are the versions present in my lib dir and vi was trying to load : /usr/local/opt/lua/lib/liblua.5.3.dylib.

Running the below symlink helped and now i can open my vi editor as usual:

ln -s liblua.5.4.dylib liblua.5.3.dylib
