RoR：$ bundle install => / usr / bin / env：ruby：不是目录

Question

I'm trying to install RoR with Mysql on Ubuntu and so far it has been a very painful and annoying experience.

Everything has been done with RVM, and upon trying to invoke:

$ rails new <some path> <some name> -d mysql

I get an error that MySQL is not installed, so I follow the instructions and run:

$ gem install bundler
=> Successfully installed bundler 1.2.3

From here the instructions via console to install MySQL are:

=> Run 'bundle install' to install missing gems.
$ bundle install

Trying to run this command results in the following output:

/usr/bin/env: ruby: not a directory

I would really appreciate some help, this is doing my head in since I just want to start programming. I expect this crap from Windows, not Ubuntu.

Q: How do I fix it?

Answer 1

Solved:

src: https://askubuntu.com/questions/182418/how-to-get-usr-bin-env-ruby-to-point-to-the-correct-ruby-environment

Adding:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"  # This loads RVM

to:

.bashrc

THEN to fix MySQL installation errors I used the second solution (67 votes) on this question:

MySQL Install: ERROR: Failed to build gem native extension

I hope this helps someone else in the future!

Answer 2

Have you tried running 'gem install mysql2'? Is mysql2 in your gem file?

Answer 3

I had the same problem. In my case source /etc/profile.d/rvm.sh did the trick!
