完全脱机安装RVM

Question

我打算为ruby脚本创建安装程序，但是我希望能够确保计算机已安装RVM。有没有一种方法可以完全脱机且不干扰地安装RVM（通过不干扰，如在创建可以执行所有操作的脚本中一样，而不是要求用户向其bash_profile或bashrc中添加某些内容）

我不是在问脚本本身，而是关于如何走这条路线的快速指针（如果可能的话）。我们还研究了这个问题，它很有帮助：

RVM-有没有一种简单的脱机安装方法？

但是有点误导，因为答案只向我们展示了如何在RVM中离线安装红宝石。我们需要能够脱机安装RVM本身，并查看脚本

https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer

我是否要包括整个脚本并将rvm_releases_url更改为其他内容？将rvm路径附加到用户的bash_profile或bashrc而不是要求他们这样做是安全的吗？

根据编辑此评论的建议。:-)

离线安装RVM：

- Download the rvm tarball: 

            curl -sSL https://github.com/rvm/rvm/tarball/stable -o rvm-stable.tar.gz

- Create and enter rvm directory: 

            mkdir rvm && cd rvm 

- Unpack the tar file : 

            tar --strip-components=1 -xzf ../rvm-stable.tar.gz

- Install rvm: 

            ./install --auto-dotfiles

            use --help to get the options

- Load rvm: 

            source ~/.rvm/scripts/rvm

下载 Ruby、rubygems 和 yaml：

- Download ruby

    o Find tar.bz2 version at: 

            https://ftp.ruby-lang.org/pub/ruby/ (check sub-directories)

    o Download with curl: :

            curl -sSL https://ftp.ruby-lang.org/pub/ruby/ruby-2.2.0.tar.bz2 -o ruby-2.2.0.tar.bz2

    o Make sure you are downloading with the extension " .tar.bz2 "

- Download rubygems

    o Find version at:

            https://github.com/rubygems/rubygems/tags
    o Download with curl:

            curl -sSL http://production.cf.rubygems.org/rubygems/rubygems-2.4.6.tgz -o rubygems-2.4.6.tgz

安装依赖项：

- Disable automatic dependencies ("requirements") fetching using the following command.

             rvm autolibs read-fail

- Manually download and install dependencies

    o Get the list of dependencies using

             rvm requirements

安装红宝石：

Clean default gems:

            echo "" > ~/.rvm/gemsets/default.gems

Clean global gems:

            echo "" > ~/.rvm/gemsets/global.gems

Install Ruby:

            rvm install 2.2.0 --rubygems 2.4.6 (this may require sudo password for autolibs)

Install any other Ruby versions you want similarly

Set default Ruby version: rvm use 2.2.0 --default

注意：ruby 和其他包应放置在“ $rvm_path/archives/ ”目录中。

安装宝石：

    There are multiple ways to install gems, we can download the gem files,
    but the best way seems to be Bundler: http://bundler.io/bundle_package.html

安装 Rails gem 的示例：

    Offline
    --------

        Create a directory:

                    mkdir gems; cd gems

        Unpack gems:
                    tar xzf gems.tgz

        Install bundler:

                    gem install bundler-1.8.3.gem

                    [ This needs internet, to avoid internet connection you need to install bundler gem using --local option with the bundler.x.x.gem file ]

        Install gems:

                    bundle install --local

卸载rvm：

    rvm implode --force

    Then remove rvm from following locations:

    rm -rf /usr/local/rvm
    sudo rm /etc/profile.d/rvm.sh
    sudo rm /etc/rvmrc
    sudo rm ~/.rvmrc

    Check the following files and remove or comment out references to rvm

    ~/.bashrc
    ~/.bash_profile
    ~/.profile
    ~/.zshrc
    ~/.zlogin

    Comment-out / Remove the following lines from /etc/profile

     source /etc/profile.d/sm.sh
     source /etc/profile.d/rvm.sh

    /etc/profile is a readonly file so use

    sudo vim /etc/profile

您也可以在这里找到安装方法...
