[mpapis]

is it about using wrong bindir?

[yakimant]

@mpapis, that is a weird moment here. I ask --bindir /usr/local/bin, but it tries /usr/bin/ anyway. (Other gems are fine, installing to /usr/local/bin

[yakimant]

I also have it in my ~/.gemrc: gem: --bindir /usr/local/bin --no-document

[yakimant]

As a workaround for this issue I disabled macOS "System Integrity Protection" and now able to write to /usr/bin/.

[mpapis]

I found it, it requires a bit of time, hope to get something to test for you around next weekend.

[mpapis]

finally got into fixing it, this can be tested with gem install executable-hooks -v 1.4.0.rc1
