node.js项目中的Node-gyp npm安装错误

Question

当我尝试将node-gyp安装到我的节点项目中以便能够安装socket.io时，我得到了这些npm错误：

我已经安装了所有dependencies的node-gyp：

• python（建议使用v2.7，不支持v3.x.x）（已安装 在Mac OS X上）
• Xcode - 您还需要通过Xcode安装命令行工具。您 可以在Xcode菜单下找到这个 - ＆gt;偏好 - ＆gt;下载这个 步骤将安装gcc和包含make
的相关工具链

任何人都可以帮我吗？

谢谢，卢克

Answer 1

It looks like you don't have permissions to write to /usr/local/lib/node_modules/node-gyp.

You could:

• give write permissions to user LukeG on /usr/local/lib/node_modules/node-gyp: sudo chown -R LukeG /usr/local
• rerun the install command using sudo

If it's your dev machine we're talking about I would go for the first option, since that's where you should install program libraries (http://www.tldp.org/LDP/Linux-Filesystem-Hierarchy/html/usr.html).
