I have browsed around but unable to find why rvmsudo is needed for passenger installation.
I am installing passenger with nginx in my server and I'm using RVM. According to the passenger user manual I need to use rvmsudo to install passenger if I have rvm installed.
Whats the difference between using rvmsudo and without using rvmsudo. Is using rvmsudo to system wide install needed despite having rvm installed locally only ? (just use gem install passenger)
Thank You !
sudo grants a command root permissions to the current user to carry a certain activity (given the user is allowed to use sudo). That said, on installing passenger you need root permission to install files at required locations.
One simple thing to do that comes to mind instantly is:
sudo rvm passenger-install-nginx-module
This won't work! Here's the explanation:
However, this won't work at all. sudo will start a new subshell.
That new subshell's environment will be completely different, and
won't contain RVM, nor will it have access to your user's RVM without
trying to hack in RVM's environment variables yourself.
Therefore you are required to use the solution provided by RVM i.e. rvmsudo. It will pass on any environment variables that RVM set up to get you to the correct Ruby along with sudo privileges, which is exactly what you need to install passenger in this example.
Running OSX Mavericks, ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0], rvm 1.25.23 (master), and rails-4.1.0 (allegedly)
I'm working through the railsapps.org book on learning rails and made it about 1/2 way through yesterday. When I stopped for the day, I closed out iTerm2 and shut off the Macbook Pro. Today, I powered up, opened iTerm, navigated to my working directory (~/rubyonrails/learn-ruby) and entered rails -v.
I see this:
`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.`
So I run sudo gem install rails and it shows that it has installed rails-4.1.0. Now rails -v still gives me the same error message above.
I tried also running rvm use ruby-2.1.1#learn-rails first and I still get the error message.
So I'm a little stuck and I can't figure out what to do to get rails working. Also, how do I go about setting up the bash environment such that I don't have to go through this each time? It would be nice to nav to my working directory and just start work without having to do a bunch of re-installation and reconfiguration each time.
Regards,
Jeff
please type in your shell:
$ bash --login
and then repeat your commands.
rails -v
Also try to call it with the full path:
like:
/your/path/to/rails -v
I think that the shell just doesn't know where rvm/rails etc is located.
You can solve this by entering:
$ source ~/.rvm/scripts/rvm
When you switch to the ruby-2.1.1#learn-rails ruby/gemset combo, and do gem list, what do you see?
The way people usually use rvm is to have every project folder specify the ruby & gemset it uses (they don't all have to be different). This is done with files called .ruby-version and .ruby-gemset. These should contain, in your case, ruby-2.1.1 and learn-rails respectively.
Set these if you haven't already, then leave the folder and enter it again. Then do bundle install to install the gems for the project into the rvm/gemset combo.
Your problem is that you ran
sudo gem install rails
The error message telling you to do this comes from your system Ruby, which doesn't know that you want to use RVM.
RVM installs gems into your user-space directory. By using sudo, you're bypassing this and installing it into (effectively) the superuser space, i.e. globally.
If you instead just run
gem install rails
then you'll be using RVM's copy of the gem utility rather than the globally installed version.
I'm new to Ruby on Rails and have just set it up in Ubuntu Linux following instructions I found here. Specifically,
As s.m. said, I uninstalled everything, then I opened another terminal session as a normal user and run:
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
then i run source /home/my-desktop-username/.rvm/scripts/rvm as a normal user NOT ROOT
then i run rvm requirements as a normal user. Then I copy the requirements and close the session, open a root session and install the requirements using sudo
Then I close the session and open a normal user session and run rvm install ruby-1.9.3-p125 if you run this command as root, it will say that rvm is not installed and will suggest that you install it using sudo apt-get install rvm Don't do that!
So basically I had two problems, the tutorials that i followed didn't say that i should run
source /home/my-desktop-username/.rvm/scripts/rvm and didn't say that I should not run rvm as root, s.m told me that. Thanks to everyone, especially to s.m
That works well, but I will have to remember to
source .rvm/scripts/rvm
every time I open a terminal to work with Ruby on Rails.
Is there a way to permanently tell Ubuntu to look in .rvm for all the Ruby stuff?
You need to add your
source .rvm/scripts/rvm
into your $HOME/.bashrc file; read the advanced bash scripting guide for more.
Normally, when I try to create a gemset using rvm,
it places any gems in $HOME/.rvm
However, on one machine when I run:
rvm use 1.8.7-p358#chris_gems --create
The command tries to write to the directory /usr/local/rvm/gems/ruby-1.8.7-p358
and as a result I get permission errors.
I tried search the web for command line arguments to "rvm" related to the install path
but didn't find anything after a 10 minute search (perhaps I'm sucking at Googling).
Also I tried setting GEM_HOME, GEM_PATH to my home directory.
But that didn't make a difference.
Any suggestions on how I can get rvm to install stuff in $HOME/.rvm
Thanks.
There are two ways to make it working:
add your user to rvm group - this will allow your user to write gemsets in system
run rvm user gemsets - this will make all new gemsets to be created in $HOME/.rvm
Based on my previous thread : RVM installed by Ruby not working? where i had installed RVM using the root user, I then had to entirely remove the RVM install and now i am installing as a user.
So i did :
Create a new user by doing : useradd newuser
Follow the instructions on the RVM website and execute the command : bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
Now, i get the error : mkdir: cannot create directory `/usr/local/rvm': Permission denied
The new user i created does not have access to this directory. I manually tried creating the folder but the same error. Please help.
EDIT : The original problem occured because i did not restart the terminal and it was still using the old settings.
Now, I got a new problem : After installing RVM, i cannot run it and it gives me an error : rvm command not found.
Here is the output of my ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
And here is output from ~/.bashrc file
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific aliases and functions
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
mkdir: cannot create directory `/usr/local/rvm': Permission denied
If you've run the rvm installer as root previously, remove /usr/local/rvm and /etc/rvmrc.
RVM is easy to install, but you are making it harder by trying to mix and match installation types. You do NOT need to create a new user. When run, RVM will create a directory in your home directory: ~/.rvm, and install everything inside it. That means you will have all the correct permissions. You do NOT need to be running as root, you do NOT need to use sudo. I'd recommend closing all your command-lines and open one fresh and start at your home directory. If you are running as root, log out, and log back in to your normal account. For a single-user install you do NOT need to be root.
For a single user, using RVM as their Ruby sandbox, use the single-user installation docs. Follow ALL the instructions on that page, INCLUDING the "Post Install" section.
Close your terminal window, and reopen it. If you have correctly followed the instructions above, typing rvm info should spit out a template of what is to come once you install a Ruby instance. If you see nothing output, or get an error, then retrace your steps in the "Post Install" section, and go through the "Troubleshooting" section. Most of the problems people have occur because they didn't bother to read the directions.
Once RVM is installed, type rvm notes and read what dependencies you need to install. If you do not add those files your Rubies installed will be missing functionality. They will work, but some of the creature comforts you'll hear about won't work and you will wonder why.
After installing the dependencies you should be in good shape to install Rubies. Type rvm list known for all the Rubies RVM can install. If you want 1.8.7 type rvm install 1.8.7, and, similarly, rvm install 1.9.2 for Ruby 1.9.2. If you want a particular revision you can add that, based on the ones in the list.
It's important to periodically update RVM using rvm get head. That will add features, fix bugs, and tell RVM about new versions of Ruby it can install if you request.
After installing a Ruby, type rvm list and it should show up in the list, looking something like this:
rvm rubies
ruby-1.8.7-p334 [ x86_64 ]
ruby-1.9.2-p180 [ x86_64 ]
Type rvm use 1.9.2 --default to set a default Ruby that will be sticky between logins. Use the version of whatever Ruby you want to default to if 1.9.2 doesn't float your boat. Once you've defined a default it should look something like:
rvm rubies
ruby-1.8.7-p334 [ x86_64 ]
=> ruby-1.9.2-p180 [ x86_64 ]
Before you begin installing gems into a RVM-managed Ruby, read "RVM and RubyGems ", in particular the part that says "DO NOT use sudo... ". I repeat. Do NOT use sudo to install any gems, in spite of what some blog or web page says. RVM's author knows better when it comes to working with RVM controlled Rubies. That is another mistake people use with RVM, again as a result of not reading the directions.
On Mac OS, you'll need the latest version of XCode for your OS. Do NOT use the XCode that came with Snow Leopard on the DVD. It is buggy. Download and install a new version from Apple's Developer site. It's a free download requiring a free registration. It's a big file, approximately 8GB, so you'll want to start it and walk away. Install XCode, and you should be ready to have RVM install Rubies.
Finally, RVM installs easily, as will the Rubies you ask it to install. I have it on about four or five different machines and VMs on Mac OS, Ubuntu and CentOS. It takes me about a minute to install it and another minute to configure it and start installing a new Ruby. It really is that easy.
I had the original issue reported in this question, "mkdir: cannot create directory `/usr/local/rvm': Permission denied" when trying to install rvm.
This is my scenario and how I solved it - maybe this will help others with this same issue.
I have Ubuntu 11.04 installed on a laptop, I only have 1 user, the one I created at install time, named nathan. When I would try to install rvm as nathan, the rvm installer saw me as root and kept trying to install rvm globally, but since I wasn't really root, it couldn't get access to create directories in /usr/local/rvm.
I'm far from an expert with Ubuntu, so I'm sure there are easier/better ways to accomplish the things I did (and I would love to learn about them), but this worked for me:
I created a new user called rubydev
I logged in as rubydev, opened a terminal and typed:
rubydev~$ bash < <(curl -B http://rvm.beginrescueend.com/install/rvm)
rvm installed correctly and I logged out of rubydev
Signed back in as nathan, opened a terminal and typed "su" (you could do all this with sudo, I am lazy)
After successfully getting root, I typed the following commands:
root: /home/nathan# cp -R /home/rubydev/.rvm .
root: /home/nathan# chown -R nathan .rvm
root: /home/nathan# chgrp -R nathan .rvm
root: /home/nathan# exit
nathan~$ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
nathan~$ echo 'export rvm_path="/home/nathan/.rvm"' > ~/.rvmrc
nathan~$ source .bash_profile
At this point, rvm was correctly installed under my home directory. To verify I typed:
nathan~$ type rvm | head -1
rvm is a function (if you don't get this response, something else is wrong)
Read the notes and installed any dependencies
nathan~$ rvm notes
I installed some rubies
nathan~$ rvm install 1.8.7-head
nathan~$ rvm install 1.9.2-head
Verified install
nathan~$ rvm list
rvm rubies
ruby-1.8.7-head [x86_64]
ruby-1.9.2-head [x86_64]
nathan~$ rvm use 1.9.2
using /home/nathan/.rvm/gems/ruby-1.9.2-head
nathan~$ rvm list
rvm rubies
ruby-1.8.7-head [x86_x64]
=> ruby-1.9.2-head [x86_x64]
Finally, I edited the preferences on the terminal itself to ensure the "Run command as as login shell" under the "Title and Command" tab was checked. It seems .bash_profile isn't otherwise processed.
I removed the rubydev user I created in step 1.
With all of that, I have a working rvm under Ubuntu 11.04 using my preferred username.
I solved this by adding
export rvm_path=~/.rvm
to ~/.bash_profile
If you first installed RVM as root and then uninstalled it. And now you are trying to install it as a non sudo user and you're getting the following error:
mkdir: cannot create directory `/usr/local/rvm': Permission denied
Make sure that you have logged out of the root session before trying to install under the user.
If you installing RVM as a user then the RVM folder should be generated in your home directory:
~/.rvm
Where there should be no permissions problems at all.
I would suggest it is picking up some old config that is left over from your system installation.
Ensure there is no /etc/rvmrc or $HOME/.rvmrc file left over because it might be using previously initialised variables from these files to construct an incorrect installation path.
if we look at this section of the bash script:
if [[ ${rvm_ignore_rvmrc:-0} -eq 0 ]]; then
for file in /etc/rvmrc "$HOME/.rvmrc " ; do
if [[ -s "$file" ]] ; then
source $file
fi
done
fi
It is trying to find one of these files, if it finds one if will run it possibly initialising rvm_path which will subsequently not be set as $HOME/.rvm by this command
rvm_path="${rvm_path:-"$HOME/.rvm"}"
I had the same issue. When I tried to create a gemset I would get a permission denied error. I just forgot to run the "rvm use 1.8.7" command first. After that I was able to create and use the gemset without any problems.
In lasts versions of rvm you need remove /etc/profile.d/ also.
This happen often if you try to install as root and then try again as a regular user.
Hope this help.
Look for file rvm.sh below /etc directory (It may be in /etc, or /etc/init.d).
Also, try some grep rvm /etc -r, so you can find some files/lines which prevent you from installing rvm in your $HOME dir.
For me running
__rvm_unload
Worked first, this was due to the fact that I had rvm installed as for multiuser.
If you installed rvm as root and you are getting permission denied issues (maybe you are deploying with capistrano as a non root user) then you could try rvm fix-permissions after doing things like rvm install 2.2.2 as root and creating a gemset as root.
Scott Bartell's solution worked for me. i am on a Digital Ocean premade image, where they had already setup rvm as root.
1. deleted /etc/rvmrc .
2. added export rvm_path=~/.rvm to ~/.bash_profile
3. logged out of ssh session to virtual machine
4. logged back in and presto!
would have commented but rep is 3 points too low :)
