I was following a tutorial on how to setup ruby on rails. http://blog.parsalabs.com/blog/2013/08/27/setting-up-a-ruby-on-rails-4-development-environment-on-a-clean-mac-os-x-installation/
I ran:
$ brew install rbenv
$ touch ~/.bash_profile
$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
and now my terminal has stopped working.
$ emacs ~/.bash_profile
-bash: emacs: command not found
when I open a new terminal window. I get the following message:
Last login: Mon Sep 23 23:25:39 on ttys001
-bash: n: command not found

Thank you Yevgeniy Anfilofyev,
The solution was to use TinkerTools and delete my ~/.bash_profile
Then start over again

I am getting a syntax error in my .bash_profile when I start up the terminal on Yosemite. Everything I have found online suggests there is nothing wrong with my syntax, although i am getting an error in line 4. Here is error, followed by the .bash_profile code. Can anyone see what is wrong? Is this affecting my ability to install rails (I seem to be having some difficulty with write permissions):
The error:
-bash: /Users/admin/.bash_profile: line 4: syntax error near unexpected token `fi'
-bash: /Users/admin/.bash_profile: line 4: `eval "$(rbenv init -)"; fi'
The .bash_profile code:
export PATH=/usr/loca/bin:$PATH
eval "$(rbenv init -)"
if which rbenv > /dev/null
eval "$(rbenv init -)"; fi
if which rbenv > /dev/null; then eval "$(rbenv init -)";
fi
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
Thanks!
The if statement on line 3 does not have a matching then. Until bash sees a then, it doesn't let you use a fi.
rvmrc is getting called when I visit that folder using 'cd'. But when I'm opening it in new terminal using ctrl+shift+t, rvmrc is not getting loaded.
Here is some more detail:
tech#pc113:~/workspace/apps$ type rvm | head -1
rvm is a function
-bash: type: write error: Broken pipe
tech#pc113:~/workspace/apps$
echo $PATH
/home/tech/.rvm/gems/ruby-1.9.3-p551/bin:/home/tech/.rvm/gems/ruby-1.9.3-p551#global/bin:/home/tech/.rvm/rubies/ruby-1.9.3-p551/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/tech/.rvm/bin:/home/tech/.rvm/bin:/home/tech/.rvm/bin
echo $GEM_HOME
/home/tech/.rvm/gems/ruby-1.9.3-p551
echo $GEM_PATH
/home/tech/.rvm/gems/ruby-1.9.3-p551:/home/tech/.rvm/gems/ruby-1.9.3-p551#global
which rake
/home/tech/.rvm/rubies/ruby-1.9.3-p551/bin/rake
Any idea?
After installing rvm when i run this
source $HOME/rvm/scripts/rvm
i get error
-bash: /root/rvm/scripts/rvm: No such file or directory
reference: Problem deploying Ruby+RVM and daemontools
I found the answer but looking at the rvmsudo script installed with
rvm, here is a working run script:
#!/bin/sh
# redirect stderr to stdout
exec 2>&1
cd /app
# load rvm
. /usr/local/rvm/scripts/rvm
# select ruby version for this application
rvm use 1.9.1
# # depending on your configuration you may need to provide the absolute path to rvm, like that:
# /usr/local/bin/rvm use 1.9.1
# build the exec command line preserving the rvm environment
command="exec sudo -u app_user /usr/bin/env PATH='$PATH'"
[[ -n "${GEM_HOME:-}" ]] && command="${command} GEM_HOME='$GEM_HOME' "
[[ -n "${GEM_PATH:-}" ]] && command="${command} GEM_PATH='$GEM_PATH' "
# this is where your real command line goes
command="${command} ruby main.rb"
# run the application
eval "${command}"
Try source ~/.rvm/scripts/rvm. Exit out of your current shell and then try again it should work.
I am trying to work with a web app made by someone else. I cloned that repo and when I cd'ed into it, the .rvmrc executed. But I am getting the following error in it:

The .rvmrc file is this:

# This is an RVM Project .rvmrc file, used to automatically load the ruby
# development environment upon cd'ing into the directory

# echo "rvm use 1.9.3" > .rvmrc

# return 1

# First we attempt to load the desired environment directly from the environment

I have not worked with .rvmrc before and am a Rails noob. Could you help me find the error?
Just create .ruby-version file containing
ruby-1.9.3-p194#ytaxi
and delete the .rvmrc file.
You are using minimal version of .rvmrc which also is buggy, you could either fix it:
if [[ -d "${rvm_path:-$HOME/.rvm}/environments" &&
-s "${rvm_path:-$HOME/.rvm}/environments/$environment_id" ]]
then
and you can switch to the new .ruby-version file:
rvm get stable
rvm rvmrc to ruby-version
I just went through the RVM install.
I did this command:
bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
and everything ran fine. Then in my user home directory, in .bash_profile I added
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
Then I started a new shell just to be sure. And then I tried
rvm
and got the error that
No command 'rvm' found
Any ideas why that might happen?
maybe it is because .bash_profile only runs on login, if you run a new shell it only executes .bashrc
You could test using
> bash -l
Did you see the "Troubleshooting your Install" section on this page.
It mentions that you need to remove return from your .bashrc. I often forget to do this on a fresh ubuntu install.
The example they give for ubuntu is to change this:
[ -z "$PS1" ] && return
# Some code here... e.g.
export HISTCONTROL=ignoreboth
to this:
if [[ -n "$PS1" ]]; then
# Some code here... e.g.
export HISTCONTROL=ignoreboth
fi
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session
