为什么不能列出全球安装的npm模块？

Question

我在跑：

npm ls -g 

它没有显示任何东西。

我很确定我已经安装了模块。如果我跑：

ls -1 usr/local/lib/node_modules/

结果是：

express
forever
fstream
fstream-ignore
generator-keystone
http-server
keystone
node-debug
node-gyp
node-inspector
npm
yo

该命令完全适用于本地安装的模块。

添加npm config ls -l的结果，可能会有更多帮助。

所以我以一种残酷的方式解决了这个问题，但是在答案的最后，你会发现对你的机器更温和的建议。

我实际上重新安装了节点。在这样做之前，我删除了前面安装的所有内容，就像其他一些帖子中所建议的那样。

这里是上一篇文章中建议的脚本的直接链接。

至于其余部分，您应该已经知道如何安装Node了。

经验教训:始终使用nvm，并在安装/卸载-g选项之前考虑几次。

现在，npm ls -g --depth=0成为了一种魅力：

/usr/local/lib
├── generator-keystone@0.3.9
├── npm@2.14.7
└── yo@1.5.0

那时，我对配置文件的更改感到好奇。

我又跑了：npm config ls -l

它的开头类似：

; cli configs
long = true
user-agent = "npm/2.14.7 node/v4.2.2 darwin x64"

然后又出现了这些新的线条，它们是缺失的：

; globalconfig /usr/local/etc/npmrc
prefix = "/usr/local"

然后保持原样：

; default values
access = null
[..]

因此，一个更合适的答案是如下所示。

最后我还没有测试它，但是如果默认情况下安装了所有的东西，那么/usr/local/etc中就会有一个文件npmrc。为了使它指向正确的位置，您应该运行：

npm config set globalconfig /etc/npmrc

希望大家都这么想。
