我需要为项目运行节点0.8.4，但是我无法安装它。我安装了nvm以便与当前系统版本的节点一起运行它，但是当我运行nvm install 0.8.4时出现错误：
Node.js configure error: No acceptable C compiler found!
Please make sure you have a C compiler installed on your system and/or
consider adjusting the CC environment variable if you installed
it in a non-standard prefix.
./configure

我首先尝试确保安装了Xcode命令行工具，看来我确实如此。 gcc确实有效。我有什么想法可以让它发挥作用吗？
