ruby 2.1.2p95
It is using right ruby version.But i guess trying to install gems in another folder.How can I fix it?

Answer 1

Have you tried installing the gem "bundler" first on your server? This gem is required to run the bundle command. SSH to your server and run the following command:
gem install bundler
Hope that helps

Answer 2

If you already have bundler installed (bundler -v) give this a try (it worked for me on Ubuntu 12.04 LTS):
1. gem uninstall bundler
2. gem update
3. gem install bundler
4. redeploy

Answer 3

It worked for me. I'm using Ubuntu 16.04.Change user below with your user name.
sudo pico /etc/profile.d/rbenv.sh
#File
export RBENV_ROOT=/home/user/.rbenv
export PATH=$RBENV_ROOT/shims:$RBENV_ROOT/bin:$PATH
#End File

Answer 4

Update:
I find the reason: my .gemrc include "gem: --user-install", so the bundle not install in rbenv, and then rbenv can't find the bundle binary in 2.1.2 path
remove the --user-install config, and reinstall bundle resovle the problem.
===================================
I found that the RBENV_VERSION env cause bundle failed, but don't known why.
I remove the RBENV_VERSION and exec the cmd on the server, it succeed.

Answer 5

If you look at your .bashrc or .bash_profile, you will see something like that:
case $- in
*i*) ;;
*) return;;
esac
Or:
[ -z "$PS1" ] && return
This prevents everything after this line to be executed if the shell is not interactive.
Capistrano does not open an interactive shell.
If you are using rbenv for example, it adds lines at the end of your .bashrc.
These lines are not executed, so your ruby environment is not loaded.
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"
Just move the rbenv lines at the start of your .bashrc, before the return explained above.
