Solution

Maybe the setup.py must be fixed to not access /usr/local for temporary files??

Additional Information

none

i ran into this issue today and the fix for me was to add the python lib to my PATH

export PATH="$PATH:/Users/[username]/Library/Python/3.8/bin"

in my .zshrc fixed for me

I ran sudo pip3 install fb-idb but I had to pip3 uninstall fb-idb before I tried to install it again.

Installing with sudo (root privileges) is a way to avoid this error, but it's probably not how one would want to handle this. After all, when doing so pip prints "WARNING: Running pip as root will break packages and permissions." That's a reasonable warning!

The reporter's suggestion that setup.py should be changed to avoid writing to /usr/local is most likely correct, as it seems that os.path.dirname(__file__) is returning /usr/local even when the file is located in another (user-writable) location. Possibly this can be resolved by wrapping in os.path.realpath to compensate for any symlinks?

@jackkinsella I'm glad that's working for you, but the original reporter shows that they were using pip3, so I expect that may not be a general solution.

This happens for me every install, for every supported version of Python. Running pip install fb-idb a second time produces no error, but also fails to install idb.

still occurs in macOS Big Sur v11.6.4 with brew installed python3.10

Using the --user option as recommended solved this issue for me.

[MVenell]

Don't use sudo, because it is not recommended. This works:

pip install --user fb-idb

If you get "idb: command not found" after successful installation, idb is installed in the directory that is not in the PATH.

find / -name "idb"

Then you know where it is and either add that directory to the PATH or move idb to some place which is in the path.
