How do I get rid of this on my bash terminal?
I suspect that the code that triggers this is found in my .bash_profile:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
Removing the line above, gives me back a prompt that Rails cannot be found, even if I have rails installed.
I had the same issue after running rvm get stable.
Since rvm needs to run in the shell session as a function, removing the line [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" from your .bash_profile or .bashrc is not an option as it will cause gems to not be found.
On my environment the cause was due to a conflict between an old installation of bash-it and rvm. If you're using bash-it and encountering this issue, this may help.
I took the following steps:
Backed up my .bash_profile (if you have .bashrc you may want to back it up as well).
Ran bash-it's uninstall script (see instructions in the link above) and removed ~/.bash-it folder.
Reinstalled bash-it.
Added to .bash_profile what was missing based on my .bash_profile backup created on step 1.
Reenabled the bash-it aliases, completions, and plugins that I needed.
As soon as I opened a new shell, I stopped receiving the error and rvm started working properly.

I am very new to Ruby on Rails. I have installed ruby, rails, gems, and RVM (and possibly some more RoR-associated files) via Mac OS terminal.
When I first installed these softwares, they seemed to work fine, and I could execute command lines like:
rails new 'project' or rails server
But then I messed around with git, directory, and some sudo bundle/gem commands a little bit because "bundle install" command wouldn't work. Honestly, I don't know what I have done, but all of these command lines have stopped working now.
They output various error messages, such as:
1) There was an error parsing 'Gemfile': Undefined local variable or method for Gemfile. Bundler cannot continue.
2) bash: /usr/local/bin/rails: /usr/local/opt/ruby/bin/ruby: bad interpreter: No such file or directory
3) ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions
4) find spec_for exe': can't find gem bundler (>= 0.a) (Gem::GemNotFoundException)
I think there were more errors, but these are all I can remember for now. Obviously, I am getting some intimidating error messages that I don't understand.
So I have come to a conclusion that I should uninstall all Ruby, Rails, Gems, RVM, and Homebrew files. But even this task looks very challenging to me.
I have tried numerous command lines in an attempt to delete them, but when I type in "rails" on spotlight, I still see lots of rails-associated files. Also, when I type "ruby -v" on terminal, it is still showing the ruby 2.0.0p648 version.
When I type in "which ruby" on terminal, it says "/usr/bin/ruby
When I type in "which rails" on terminal, it says "usr/local/bin/rails
In short, I just want to delete all of these RoR-related files, softwares, and every trace of them, and reinstall them clean. Please please help me. I do not want to give up coding. Is it too late to say that I'm sorry?

Ruby is installed on OS X by default. So you don't want to remove that, there are things that might require ruby that has nothing to do with rails or your rails projects, you should ignore it. (and you should probably not use spotlight for finding dev files, its just confusing as to what is safe and what is not to play with)
Secondly, you'll hardly EVER use sudo for any rails-related work on your mac, so if a tutorial wants you to run that command, don't.
And lastly, its possible it's not as bad as you think. So there's 2 steps. 1 - Fix your rvm environment and 2 - fix your gemfile
TO RESOLVE
--Start be reinstalling RVM
\curl -sSL https://get.rvm.io | bash
Now because it's changed your shell environment (added variables and aliases) and because you've changed some things that are unpredictable... Log out, and log back into your mac.
** Which ruby is in use now? **
which ruby
If you're system is still showing /usr/bin/ruby then you'll need to edit your shell profiles. Because I don't know what you might have done, or what shell env you're using I'll just be thorough. Any excess won't hurt.
You'll review (in the editor of your choice) 4 hidden files in your home directory
/Users/yourhome/.profile
/Users/yourhome/.bashrc
/Users/yourhome/.zshrc
/Users/yourhome/.bash_profile
If you're using bash, then make sure your bash_profile has in it
source ~/.profile
In the bashrc nad zshrc files make sure the rvm path exists
export PATH="$PATH:$HOME/.rvm/bin"
In the .profile file make sure this command exists
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
-- Once you've saved your changes, log out and back in (you shouldn't have have to do this but again, just being thorough).
Once that is done, you should be able to install a ruby -
rvm install ruby-2.2.3
Now if you say rvm use ruby-2.2.3 and then which ruby, you should see a pointer to your home directory where rvm lives.
* Now to fix the Gemfile *
You have an encoding problem, which is what caused you the errors that made you see spots in the first place. If you paste the contents of the file here
(in a terminal in the directory of your rails project)
cat Gemfile
Paste those contents here and it can be fixed.
My system was fine, but today, after installing MySQL server, I can't use the terminal to program my Rails application.
When I open a terminal session, I see:
Last login: Sun Dec 8 13:31:06 on console
-bash: [: missing `]'
-bash: rt: command not found
I tried searching for this error but can't find a solution.
I am running Mac 10.7 OS X.
No commands pertaining to Ruby on Rails are found.
I built an application and installed Rails, but when I run a Rails command I get:
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
How do I fix this?
My bashrc file contains only one line:
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
My bash profile contains following:
export PATH=$PATH:/usr/local/mysql/bin
[ [-s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
rt PATH=$PATH:/usr/local/mysql/bin
I checked history and this is what I ran
vi .bash_profile
vi .bash_profile
user#computer:$ mysql -u root
mysql -u root
vi .bash_profile
mysql -u root
/usr/local/mysql-5.6.15-osx10.7-x86_64/bin/mysqld_safe ; exit;
mysql
What else can I show to help with this problem?
Your .bash_profile is messed up. Modify what looks like this:
[ [-s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
rt PATH=$PATH:/usr/local/mysql/bin
To look like this:
[[-s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
export PATH=$PATH:/usr/local/mysql/bin
As #TinMan pointed out, you'll want to remove the export PATH line from your .bashrc file.
I had a similar problem (although I'm running Ubuntu). When I opened a new terminal and navigated to my project root, I was surprised to find that Rails was not recognized as a program. I checked the version of Ruby and noted that there was a discrepancy between the two terminals I had open. When I tried to switch Ruby versions with RVM, I was told
You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
so I ran /bin/bash --login. Then, I was able to switch to Ruby 2.1.1 with RVM use ruby-2.1.1 and all my rails commands worked again.
Basically what happened is that RVM only installs gems locally for each Ruby verison. Unless you select the version of Ruby that you were using when you installed the gem, you won't be able to use the gem unless you reinstall it.
I came to this page after receiving this error with a slightly different cause. While the CDub's answer is directly applicable to OP's question, I would generally recommend users of Mac OS X Terminal who have this error to do the following:
Open ~/.bash_profile in a text editor.
Look for any instances of "rt" at the beginning of a line.
Change all instances to "export".
It looks like some packages out there are writing a command into ~/.bash_profile that Mac OS X does not like, and we need to manually correct this.
For reference, I am on OS 10.10.2.
I know the above question is very common question. I have gone through multiple posts on this topic. But I didn't get any resolution.
I have installed rvm locally. We already have the installation files. SO went into the folder and run the install command.
$ ./install
Then I checked ./rvm folder in the Users home folde
$ cd ~/.rvm
folder exists. Hence Installation is successful.
Now I am typing rvm in the command line
$ rvm
I am getting below exception
$ rvm
-sh: rvm: command not found
After reading the multiple articles in stackoverflow on this issue, I learned that I have to add the below lines in .bash_profile as I am using Mac OSX 10.7.3
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
Even after I am getting same exception while typing rvm. Is there any thing extra I need to do? or Am I missing some thing? Please help
Steps to try out:
Log out and login to your system.
Open a new terminal and manually run
source $HOME/.rvm/scripts/rvm
then
rvm
Check these work-arounds.
Update:
To avoid running
source $HOME/.rvm/scripts/rvm
every time you open a terminal, include this line into ~/.MacOSX/environment in your Mac (This is similar to ~/.bashrc in GNU/Linux-based systems under $home aka ~ directory).
In my case, i am using Ubuntu Bash in Windows 10 and to fix the problem i used:
source /usr/local/rvm/scripts/rvm
For those that are doing this in 2018 just
add
source $HOME/.rvm/scripts/rvm
to your .bash_profile within your home directory.
you need to enable login shell in terminal emulator preferences, sometimes it is needed to use /usr/bin/bash --login, here is an example https://rvm.io/integration/gnome-terminal/
after enabling login shell you need to close terminal application and open it fresh.
I just had to open a new Terminal session.
After I installed it using:
curl -sSL https://get.rvm.io | bash -s stable --ruby
rvm install 2.2
For Ubuntu 18.04, I had to run the command below to solve the issue after rvm was installed using instruction from here.
source /usr/share/rvm/scripts/rvm
This is one of other options available for RVM:
source /etc/profile.d/rvm.sh
I am a newbie RoR developer (and pretty newbie for programming in general). I followed the installation instructions on http://rvm.beginrescueend.com/rvm/install/ to a T. I added...
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
...to my .profile and .bash_profile (at the very end) and yet I still cannot load RVM as a function. Note that I am getting -bash: ??: command not found" in Terminal.
I'm going through the rails by example tutorial series. I'm trying my best to find solutions prior to asking questions, so if I have missed anything I apologise.
Every time I need to boot up RVM from the command line in terminal I need to punch a command so that RVM initialises: source ~/.rvm/scripts/rvm
Is this normal? It seems that I cant get the RVM commands to work unless I punch in this code prior. Note I only have to enter the command once, not every time I need to enter an RVM command.
Many thanks for your help.
Put this in your ~/.profile or ~/.bashrc:
# This loads RVM into a shell session.
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
So you don't have to manually type it for every session.
Further Tip
If you want to use gnome terminal (comes as standard in Ubuntu) with rvm, you can do the following:
Edit the default profile. Check the following setting:
"Run command as a login shell"
This will stop loading the standard .bashrc by default. Fix this by making a soft link of .rvmrc pointing at .bashrc in your home directory
cd
ln -s .bashrc .rvmrc
Try closing terminal and then re-opening it to install a specific version of Ruby as seen in this video at 2:32.
For example, I typed curl -L https://get.rvm.io | bash -s stable --ruby
Then I quit and reopened the terminal, typed rvm install 2.2.3 and it worked.
If your rvm command is not found:
(to check, enter the command rvm list, which gives:)
/bin/bash: rvm: command not found
To solve it, follow these steps:
Install rvm
whereis rvm
rvm: /home/username/.rvm/bin/rvm
source ~/.rvm/bin/rvm
now test your rvm again
rvm list
