"could not load the C extension" -- Ruby versions match, followed all instructions

[vjsingh]

Hey all,

I have tried everything, and can't get command-t to work on my new mac.

This is my error message upon trying to start command-t in vim: "command-t.vim could not load the C extension. Please see INSTALLATION and TROUBLE-SHOOTING in the help. Vim Ruby version: 2.5.0-p0 For more information type: :help command-t"

My vim is installed using HomeBrew. Opening "/usr/local/Cellar/vim/8.0.1400_4/bin/vim" and running 'ruby puts "#{RUBY_VERSION}-p#{RUBY_PATCHLEVEL}"', I get "2.5.0-p0"

Ran these commands on an to install a new version of command-t (freshly installed with vim-plug): ext/command-t: rvm use 2.5.0 ext/command-t: ruby --version --> ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin17] ext/command-t: ruby extconf.rb; make --> (No Errors)

I tried to "brew uninstall vim; brew install vim," but none of these are working.

Beating my head against the wall. Any help with troubleshooting? Not sure what else to try. Thank you very much for an excellent plugin.

Can you share the full output of a clean build of Command-T and Vim ":version"?

Yep, here you go. Thank you for the help.

➜ command-t git:(master rvm use 2.5.0 Warning! PATH is not properly set up, '/Users/Varun/.rvm/gems/ruby-1.8.7-p371@wordless/bin' is not available. Usually this is caused by shell initialization files. Search for 'PATH=...' entries. You can also re-add RVM to your profile by running: 'rvm get stable --auto-dotfiles'. To fix it temporarily in this shell session run: 'rvm use ruby-1.8.7-p371@wordless'. To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.

@wincent Still haven't been able to get this to work. Let me know if there's anything further I can offer for debugging

[daniyalzade]

I am on the same boat @vjsingh . Any luck here?

[vjsingh]

@daniyalzade No luck at all, sorry. Totally dead-ended.

Did you also recently upgrade your mac?

[wincent]

I would just get rvm out of the loop and use the system Ruby.

[daniyalzade]

genius! that did the trick for me :)

Below were the list of steps to get it working @vjsingh

cd ~/.vim/bundle/command-t/ruby/command-t/ext/command-t
rvm implode # gets rid of RVM
ruby extconf.rb
make clean
make

[vjsingh]

Wow, it worked! woooo happy days are here again!!!

Thanks @wincent. And thanks @daniyalzade for posting the commands you used, worked perfectly for me.
