Ruby 安装的 RVM 不起作用? [英] RVM installed by Ruby not working?

问题描述

我使用 RVM 网站上提到的单一指令(使用 git)安装了 RVM.

然后我使用以下方法安装了 Ruby 版本 1.9.2 和 1.8.7:

rvm install 1.9.2rvm 安装 1.8.7

但是，我找不到 Ruby 二进制文件.当我尝试执行命令时，出现以下错误:

[root@server1 support]# rvm 使用 1.9.2使用/usr/local/rvm/gems/ruby-1.9.2-p136[root@server1 支持]# ruby-bash: ruby​​: 命令未找到

这是rvm info的输出:

[root@server1 支持]# rvm 信息系统:系统:uname: "Linux server1.myserver.com 2.6.18-194.26.1.el5.028stab070.14 #1 SMP Thu Nov 18 16:34:01 MSK 2010 x86_64 x86_64 x86_64 GNU/Linux"bash: "/bin/bash => GNU bash, 版本 3.2.25(1)-release (x86_64-redhat-linux-gnu)"zsh:=> 未安装"房车:版本:rvm 1.2.6 by Wayne E.

解决方案

RVM 需要对 ~/.bashrc 或 ~/.bash_profile 进行少量添加以对其进行初始化当您登录时.它在安装后部分的安装文档中指定.你这样做了吗?

<小时>

根据您的 rvm info 输出，您似乎还没有完成安装.输出中的所有条目都应具有相应的值.所以，我怀疑你没有添加:

[[ -s "$HOME/.rvm/scripts/rvm" ]] &&."$HOME/.rvm/scripts/rvm" # 这会将 RVM 加载到 shell 会话中.

到你的 ~/.bashrc 或 ~/.bash_profile 然后开始一个新的会话.

如果您正在进行多用户"安装，那么您需要做更多的事情.您是否修改了 /etc/profile，或者，如果您使用 Bash 作为 shell，您是否修改了 /etc/bash.bashrc 以包括:

<前># 如果已安装，则加载 RVM，# 首先尝试加载用户安装# 然后尝试加载 root 安装，如果用户安装不在那里.if [ -s "$HOME/.rvm/scripts/rvm" ] ;然后.$HOME/.rvm/scripts/rvm"elif [ -s "/usr/local/rvm/scripts/rvm"] ;然后./usr/local/rvm/scripts/rvm"菲

并启动了一个新的 shell?

我个人不喜欢多用户安装和单用户安装一样，也不推荐它，但您的里程可能会有所不同.

仅供参考:去年在 IRC 上与 RVM 维护人员的讨论中，他们告诉我他们不推荐系统范围的安装，而是推荐本地单用户"安装，即使是服务器也是如此.

I installed RVM using the single instruction mentioned at the RVM website (using git).

Then I installed Ruby version 1.9.2 and 1.8.7 using:

rvm install 1.9.2
rvm install 1.8.7

However, I cannot find the Ruby binary. When I try to execute the command, I get the following error:

[root@server1 support]# rvm use 1.9.2
Using /usr/local/rvm/gems/ruby-1.9.2-p136

[root@server1 support]# ruby
-bash: ruby: command not found

Here is the output of rvm info:

[root@server1 support]# rvm info

解决方案

RVM requires a minor addition to your ~/.bashrc or ~/.bash_profile to initialize it when you log-in. It is specified in the installation docs in the Post Install section. Did you do that?

---

Per your rvm info output, it looks like you haven't completed your installation. All the entries in the output should have corresponding values. So, I suspect you haven't added:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"  # This loads RVM into a shell session.

to your ~/.bashrc or ~/.bash_profile and then started a new session.

If you are doing a "Multi-User" installation then you'll need to do a lot more. Have you modified /etc/profile, or, if you are using Bash as your shell, have you modified /etc/bash.bashrc to include:

# Load RVM if it is installed,
#  first try to load  user install
#  then try to load root install, if user install is not there.
if [ -s "$HOME/.rvm/scripts/rvm" ] ; then
  . "$HOME/.rvm/scripts/rvm"
elif [ -s "/usr/local/rvm/scripts/rvm" ] ; then
  . "/usr/local/rvm/scripts/rvm"
fi

and started a new shell?

Personally I don't like the multi-user install as much as the single-user install, and don't recommend it but your mileage might vary.

---

As a FYI: In a discussion with the RVM maintainers on IRC last year, they told me they do not recommend the system-wide installation, and instead recommend the local "single-user" installation, even for servers.
