rbenv shell command not found

[mdesantis]

Environment:

$ uname -srvm
Linux 3.11.0-11-generic #17-Ubuntu SMP Tue Oct 1 19:42:04 UTC 2013 x86_64
$ echo $SHELL
/usr/bin/fish
$ rbenv --version
rbenv 0.4.0-65-gff23666

When I execute rbenv shell jruby-1.7.4 rbenv outputs rbenv: no such command `shell' and the ruby environment doesn't change.

In order to mitigate this issue I'm using this:

function rbenv-shell
  set --local RUBY_VERSION $argv[1]

  if test "$RUBY_VERSION" = "--unset"
    set --global --export --erase RBENV_VERSION
  else if test -n "$RUBY_VERSION"
    set --global --export RBENV_VERSION $RUBY_VERSION
  end

  rbenv version
end
complete --command rbenv-shell --exclusive --arguments "--unset (rbenv versions --bare)"

How did you set up rbenv? Did you follow instructions from the official README? Do you have this line in your .bash_profile or .zshrc (depending on the shell you use):

eval "$(rbenv init -)"

rbenv shell is a special command that only works if you've set up the rbenv() function in your shell by means of eval'ing rbenv init - output.

[mdesantis]

Since I use fish shell I set this in the config (as written in the issue #195 ):

set PATH $HOME/.rbenv/bin $PATH
set PATH $HOME/.rbenv/shims $PATH
rbenv rehash >/dev/null ^&1

Reading better the issue 195 it is a known bug, isn't it? This comment says so

[mdesantis]

Here there is a patch which makes rbenv shell work, I'm trying it and it works; while this version, which supports short names, works but just correcting a tip: rbenv version -- bare should be rbenv version --bare (without the space)

[mislav]

Disregard the Coderwall tips. rbenv now supports fish shell in the master version. Upgrade to the latest version:

cd ~/.rbenv
git pull

Then, in your config.fish:

set PATH $HOME/.rbenv/bin $PATH
. (rbenv init -|psub)

[mdesantis]

Thank you! it solves the issue. I added it to the wiki https://github.com/sstephenson/rbenv/wiki/Unix-shell-initialization , if you want you can check if it is in the right place

[mislav]

That wiki page is about shell in general and is not a good place to add rbenv-specific documentation. I reverted your change. Don't worry about adding this documentation for now; I'll see that it's added to our README.

[mdesantis]

Ok, no problem. Thank you again

[espen]

If I add '. (rbenv init -|psub)' to config.fish I get a lot of errors when loading a new shell instance. Just adding 'rbenv init -|psub' works but I am unable to use 'rbenv shell'. Using v.0.4.0 through homebrew.

[mislav]

@espen Can you update to latest head and try again? brew upgrade rbenv --HEAD

[espen]

Yeah just figured out that the brew package v.0.4.0 was not the same as v.0.4.0 in master. Works great. Thanks :D

i end up with
krirou@iHAL ~> rbenv
env: bash\r: No such file or directory

• just did a $brew upgrade rbenv --HEAD
• i've patched my .config/fish/fish.config as well

ideas?

[mislav]

@kitofr You seem like you have another kind of issue. What is the output of which bash? How does rbenv setup in your fish.config looks like?

[kitofr]

Oh, sorry for not posting the necessaries earlier; quite new to fish and rbenv.

krirou@iHAL ~> which bash
/bin/bash

krirou@iHAL ~> cat .config/fish/config.fish 
set -x LC_CTYPE sv_SE.UTF-8
# https://github.com/sstephenson/rbenv/issues/459
set PATH $HOME/.rbenv/bin $PATH
. (rbenv init -|psub)

[mdesantis]

@kitofr try status --is-interactive ; and source (rbenv init - | psub) instead of . (rbenv init -|psub)

[kitofr]

same thing unfortunately :(

[mislav]

@kitofr You said you installed rbenv --HEAD from Homebrew. If you did that, then remove this line from your config.fish, as you don't need it:

set PATH $HOME/.rbenv/bin $PATH

That line only applies if you've installed rbenv directly to ~/.rbenv from git.

Alternatively, if you want to keep your installation from git in ~/.rbenv (and I recommend that), then brew uninstall rbenv, keep the PATH line in shell config, and cd ~/.rbenv && git pull to ensure you've got the latest version. Then try again.

[kitofr]

Still no luck :(... i'll peek in the code and see if I can spot anything. I suppose it's something odd with my environment.

Thanks for all the help.

You can open a new issue, since your problem is unrelated to the original issue here. Include the following information:

1. which -a rbenv
2. rbenv --version
3. fish version
4. latest contents of config.fish
5. What command do you run when you get the error; is the error always the same; the exact output including the error

[kitofr]

Hey!

I've opened a new issue here:
#541

Cheers and thanx for all the help,
Kristoffer

I solved it in ubuntu by installing coreutils again
