Node.js：无法安装 iconv 模块

Question

我尝试安装iconv 模块，但它总是停留在：

^Cyippeeyippee@mini: server$ npm install iconv
npm http GET https://registry.npmjs.org/iconv
npm http 304 https://registry.npmjs.org/iconv

> iconv@1.2.3 install /Users/yippeeyippee/Desktop/nodejs/tinman/server/node_modules/iconv
> node-gyp rebuild

gyp http GET http://nodejs.org/dist/v0.8.7/node-v0.8.7.tar.gz
gyp http 200 http://nodejs.org/dist/v0.8.7/node-v0.8.7.tar.gz

我不知道发生了什么，成功还是失败，我该如何解决这个问题？

更新：

等了半天，得到如下失败信息：

xcode-select: Error: No Xcode is selected. Use xcode-select -switch /Applications/Xcode.app to select /Applications/Xcode.app, or see the xcode-select manpage (man xcode-select) for further information.

Answer 1

仅命令行工具（无 Xcode）方法

1. 下载并安装 Mac OS X Developer Command Line Tools
2. 运行sudo xcode-select --switch /usr/bin。详情请见homebrew issue 10245
3. 重试npm install iconv

Xcode 版本（未经我测试）

1. 下载并安装完整版Xcode
2. 再次尝试您的npm install iconv。如果它有效，你就完成了。
3. 如果您遇到同样的错误，请尝试sudo xcode-select --switch /Applications/Xcode.app，然后重试您的npm install iconv

Answer 2

在这一步node-gyp安装程序下载node.js源代码。这可能需要很长时间，具体取决于您的连接速度。例如：我在位于中国的连接速度非常慢的服务器上等待大约 20-25 分钟。
