bash: /home/XXX/.rvm/scripts/rvm: No such file or

问题:

I just walk-through with the installation of Ruby on Rails on ubuntu using RVM.

First I have logged me as root user.

Then I started with the following commands.

1. \curl -sSL https://get.rvm.io | bash -s stable --rails

   It has been installed without any error.

2. source ~/.rvm/scripts/rvm

   When I run this command. It showing the error as bash: /home/XXX/.rvm/scripts/rvm: No such file or directory

I added the [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" command in my .bashr file.

Thanks in advance.

Install RVM:

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

Now you will get a success message. Then, run this command:

\curl -sSL https://get.rvm.io | bash -s stable

See http://rvm.io/ for more info.

After installing rvm, try:

source ~/.rvm/scripts/rvm

If the above command throws some issue, try this command:

source /usr/local/rvm/scripts/rvm

I think they may have moved some files around fixed with:

source /usr/share/rvm/scripts/rvm

Firstly no need to go for sudo access while installing rvm, just follow the very basic commands below

   $\curl -sSL https://get.rvm.io | bash -s stable

This will install rvm.

   $ rvm list known
   # MRI Rubies
   [ruby-]1.8.6[-p420]
   [ruby-]1.8.7[-p374]
   [ruby-]1.9.1[-p431]
   [ruby-]1.9.2[-p320]
   [ruby-]1.9.3[-p545]
   [ruby-]2.0.0-p353

Install a version of ruby as required.

   $ rvm install 2.0.0-p353

Now you can use the version of ruby for which you need to install rails as a gem.

   $ rvm use 2.0.0

Also you can make it default if you want so

   $ rvm use 2.0 --default

Next you can install rails as a gem.

    $ gem install rails

gems should never be installed with sudo access as they change from project to project. rvm helps in managing the different versions of ruby in one m/c. You can also use gemsets to isolate gems and specific versions from one application to another.

回答5:

just create ~/.rvm/scripts/rvm directories, then try to install rvm but make sure you are not logged in as root.

回答6:

Is generally not recommend to install RVM as a root user because of umask security risk. Try running these commands as a user.

Downloading RVM (Do not sudo this command)

\curl -sSL https://get.rvm.io | bash -s stable --rails

Then you'll need to add the location to sources(You'll probably need to reload your bash for rvm to work)

source ~/.rvm/scripts/rvm

You can install your desired version like so(replace ruby_version with one you would like to install, eg 2.1.4)

rvm install ruby_version

To list the available version on your machine

rvm list

To use a version of ruby run

rvm use ruby_version

If you have any trouble refere to the RVM website

回答7:

As root, you traditionally don't have a /home folder. Root's home is different than a normal user.

You very likely don't want to install RVM as root.

Please do read the information at http://rvm.io specifically the installation notes.

回答8:

Can you use sudo find to locate the correct path of the rvm directory? If you find the path, you should be able to rerun the source ~/.rvm/scripts/rvm command with the correct path.

Also, I fully agree with the previous answers about not creating it as root. DigitalOcean was a pretty good tutorial on adding users https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-14-04

Alright so when you get a failure message "No such file or directory", type

\curl -L https://get.rvm.io | bash -s stable

in your terminal. There will be a GPG signature verification failure. Bellow that failure there would be a link for github and a key something like this

gpg2 --recv-keys 409B6B...

So download a tar file from the github link and run this code to install GPG:

sudo apt install gnupg2

and run that key :

gpg2 --recv-keys 409B6B...

next run the code:

\curl -L https://get.rvm.io | bash -s stable

it will show you installing the rvm and then you can run:

source ~/.rvm/scripts/rvm

thats it you are good to go

Your surest bet is to use home brew. Funny part is if you try brew upgrade ruby, you will have an error if brew wasn't used to install ruby in the first instance so use:

$ brew install ruby

Then afterwards use

$ brew upgrade ruby

You may need to close and reopen your terminal to see the effect of the upgrade by typing

$ ruby -v
