我查看了所有类似的答案，但没有一个完全符合我的情况，也没有任何一种解决方案对我有效。
gem environment 和 sudo gem environment 的结果相同：
RubyGems Environment:
- RUBYGEMS VERSION: 1.5.3

OSX 10.8.4
echo $PATH /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/home/ava/.rvm/bin:/home/ava/bin
gem install <gem-name> 的结果为
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /usr/local/lib/ruby/gems/1.8 directory.
我可以通过sudo安装相同的软件，但为什么不能直接安装？我做错了什么吗？
更新：
根据评论和这篇文章，我运行了以下命令：
rvm implode 然后重新安装稳定版本。
rvm install 1.9.3 或其他任何Ruby版本的安装都会失败。
Error running '__rvm_make -j24',

rvm list和which ruby的输出是什么？基本上你的电脑上安装了两个 Ruby 1.8，你需要使用安装在 /home/ava/.gem/ruby/1.8 路径下的那个，而不是 /usr/local/lib/ruby/gems/1.8。设置 rvm 使用正确的 Ruby 应该可以解决这个问题。 - Lavixuext-ree-1.8.7-2011.12所使用的ruby是/usr/local/bin/ruby。 - Avarvm remove ext-ree-1.8.7-2011.12.rvm install 1.8.2. 然后使用rvm use '新安装的Ruby版本' --default设置默认Ruby版本。 - Lavixurvm install 1.8.2失败，并出现以下错误提示：http://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.2.tar.gz或ruby-1.8.2.tar.gz没有校验和，因此无法验证。 - Ava
