通过RVM安装Ruby 1.9.2失败

Question

我按照rvm上的官方指南安装了RVM。 我在rvm install 1.8.7安装了Ruby 1.8.7，然后在rvm 1.8.7 --default中将其设置为默认值。

然后我尝试使用rvm install 1.9.2 ，还尝试了rvm install 1.9.2-head 。 一切顺利，直到我到达“ ruby​​-1.9.2-head-＃installing-part”。

然后我收到了一个巨大的错误列表，抱怨我的* nix bash命令：

如果输入rvm 1.9.2 --default得到相同的错误输出，并且$PATH变量将被完全清除。

有人对此问题有解决方案吗？

要重新安装并重新启动RVM，只需执行rm -rfv ~/.rvm和rm ~/.rvmrc如果有）。

我有同样的问题，看起来整个RVM脚本都坏了。 rvm install ree命令没有失败，但是运行rvm use ree我开始遇到问题。

$PATH变量不是空的，就像rvm use 1.9.2 ，但是它错过了/bin和/usr/bin这样的重要路径。

这是一个示例控制台会话：

calas@chamonix:~$ ls
Desktop  dev  Documents ...
calas@chamonix:~$ rvm use ree
info: Using /home/calas/.rvm/gems/ree-1.8.7-2010.02
calas@chamonix:~$ ls
Command 'ls' is available in '/bin/ls'
The command could not be located because '/bin' is not included in the PATH environment variable.
ls: command not found
calas@chamonix:~$ rvm info
Command 'sed' is available in '/bin/sed'
The command could not be located because '/bin' is not included in the PATH environment variable.
sed: command not found
bash: grep: No such file or directory
bash: mkdir: No such file or directory
bash: grep: No such file or directory
/usr/bin/env: bash: No such file or directory

运行rvm info ， $PATH变量为空。

我用rvm implode删除了整个RVM安装并重新安装，但这没有用。

我猜解决方案是降级或等待新版本。

解决方案已在git源中准备好：

rvm update --head && rvm reload

并解决了问题，谢谢韦恩！

这样的事情刚发生在我身上，经过仔细检查，我只是在路径上缺少了/user/bin 。 但为什么？

事实证明，经过一番调查， 我在$PATH之前缺少一个冒号 ，这导致默认路径（即/ user / bin）中的第一个目录被忽略。

一旦我改变了这个：
export PATH=$SCRIPTS:$WORKSPACE:$ANDROID_HOME:$HEROKU$PATH
对此：
export PATH=$SCRIPTS:$WORKSPACE:$ANDROID_HOME:$HEROKU:$PATH

（注意冒号在最后一个“ $”之前添加）
一切又恢复了。 显然，您的路径会有所不同，但请检查是否缺少冒号。
