Question

I try to run gem pristine --all and I keep getting this in the console.

when I run gem pristine --all I get this:

Answer 1

Update your RVM to > 1.26.11 or stable with:

rvm get stable

Taken from here.

Answer 2

For me, it was as simple as installing Bundler:

gem install bundler

Answer 3

I know this is an old case, I ran into an error like this recently and none of the solutions had helped. Here is how I fixed the issue.

I was receiving this error when running any 'gem' command:

Ignoring executable-hooks-1.3.2 because its extensions are not built.

What I had done prior to getting this error was upgraded my ruby with rvm

rvm upgrade 2.0.0 2.4.0

I fixed the issue by Uninstalling 2.4.0

rvm uninstall 2.4.0

Then Reinstalling it

rvm install 2.4.0

Problem fixed.
