node.js - 在 Node 上安装 bcrypt 时出现 ELIFECYCLE 错误。 CXX 错误？

Question

安装 OS X Mountain Lion 和 XCode 后，我收到此错误:

Jonathans-MacBook-Air:fme jong$ npm install bcrypt
npm http GET https://registry.npmjs.org/bcrypt/0.7.0
npm http 304 https://registry.npmjs.org/bcrypt/0.7.0
npm http GET https://registry.npmjs.org/bindings/1.0.0
npm http 304 https://registry.npmjs.org/bindings/1.0.0

> bcrypt@0.7.0 install /Users/jong/Workspace/fme/node_modules/bcrypt
> node-gyp rebuild

我有一种感觉，它不知道该使用哪个编译器。我该如何解决这个问题？

Answer 1

显然我只需要从 XCode 的下载面板安装命令行工具
