ruby-on-rails - Rails 中的参数列表太长

Question

我已经阅读了很多关于此错误的帖子，但我似乎无法弄清楚任何事情。出于某种原因，当我在命令行(rails s、gem list、sudo gem update --系统等)

/Users/username/.rvm/bin/gem: line 6: /Users/username/.rvm/bin/gem: Argument list too long

/Users/username/.rvm/bin/gem: line 6: /Users/username/.rvm/bin/gem: Unknown error: 0

它指向的文件如下所示:

#!/usr/bin/env bash

if [[ -s "/Users/username/.rvm/environments/ruby-1.9.2-p180@rails31" ]]
then
  source "/Users/username/.rvm/environments/ruby-1.9.2-p180@rails31"
  exec gem "$@" #The line it points at
else
  echo "ERROR: Missing RVM environment file: '/Users/username/.rvm/environments/ruby- 1.9.2-p180@rails31'" >&2
  exit 1
fi

我真的是 Rails 的新手，所以也许这很简单，但我什么也做不了。

更新:

我重新安装了 rvm，但现在我收到一个新错误。我试图安装不同版本的 ruby​​，一切正常，直到:

ERROR: Error running ' ./configure --prefix="/Users/username/.rvm/usr"  ', please read /Users/username/.rvm/log/ruby-1.9.2-p180/yaml/configure.log

来自答案的评论:

1. 重新安装 RVM，rvm 内爆
2. 然后得到相同的安装过程停止是因为 1.9.3-p0 需要一个非 LLVM 版本的 GCC，它是不再包含在 XCode 表单版本 4.2 中。 rvm 安装 1.9.3-p0 --with-gcc=clang
