require': cannot load such file -- thread_safe (LoadError) when running any middleman command #1342

Closed brpaz closed 10 years ago

brpaz commented 10 years ago

When I try to create a new middleman project (using middleman init command) I allways get the following error. I had another middleman project already set up and if I run middleman commands inside that project it works fine.

What I am missing?

Looks like an installed Middleman extension might be acting up. When Middleman is run inside a project, it uses Bundler to protect itself from these kind of issues. Unfortunately, outside a project, it has to run through Rubygems which has all kinds of issues.

Like, you have a global gem with the middleman- prefix that is causing some issues. I'd suggest running gem list | grep middleman and uninstall anything that you don't need for middleman init. So, just keep middleman-core and middleman unless you're using a middleman- prefixed template gem.

I uninstalled all middleman related gems and reinstalled middleman and now everything works fine again. Thanks.
