我无法启动 Rails 服务器

Question

I think it must be a problem related to the path. I made the step by step of this page https://meekgonkey.blogspot.com/2014/02/installing-ruby-rails-on-manjaro-linux.html

Answer 1

I had a similar error while running rails new <ProjectName> . Managed to create the project using a workaround but later got the exact same error while trying to rails s .

For some reason bundle exec rails s would throw a lengthy cryptic error and end with an abort and core dump.

Uninstalling all gems and reinstalling them for my rbenv version fixed it for me.

$ gem uninstall -aIx

$ gem install rails -v 6.1.4.1

$ rbenv rehash

(At this point rbenv threw another error saying /home/.../.rbenv-shim existed, then I ran..)

$ rm /home/username/.rbenv/shims/.rbenv-shim
$ rbenv rehash
