I just walk-through with the installation of Ruby on Rails on Ubuntu using RVM.
First I have logged in as the root user.
Then I started with the following commands.
\\curl -sSL https://get.rvm.io | bash -s stable --rails
It has been installed without any error.
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"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
command in my .bashr file.
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
我认为他们可能已经移动了一些固定的文件:
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.
只需创建 ~/.rvm/scripts/rvm 目录,然后尝试安装 rvm,但请确保您没有以 root 身份登录。
This source /usr/share/rvm/scripts/rvm
works for me on ubuntu 20.04. I changed the local in /usr/local/rvm/scripts/rvm
to share I assume that you have installed the rvm.
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
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.
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
如果您通过 apt-get 安装 rvm,您可以将以下行添加到 ~/.zshrc 或 ~/.bashrc
source /etc/profile.d/rvm.sh
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
