node.js - 为什么无法列出全局安装的 npm 模块？

Question

我正在运行:

npm ls -g 

它没有显示任何内容。

我很确定我已经安装了模块。如果我运行:

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

该命令完美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，但在答案的最后，你会发现对你的机器更加温和的建议。

我实际上重新安装了 Node 。在执行此操作之前，我按照其他post中的建议删除了以前安装的所有内容。 .

Here是上一篇文章中建议的脚本的直接链接。

对于其余部分，您应该已经知道如何安装 Node。

经验教训:始终使用 nvm 并在使用 -g 选项安装/卸载之前三思而后行。

现在npm ls -g --depth=0 可以发挥作用:

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

当时我对配置文件的更改感到好奇。

我再次运行: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"

然后是这些缺失的新行:

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

然后保持不变:

; default values
access = null
[..]

因此，更合适的答案如下。

我最终还没有测试它，但是如果你默认安装了所有内容，那么/usr/local/etc 中会有一个文件 npmrc 。要使其指向正确的位置，您应该运行:

npm config set globalconfig /etc/npmrc

希望大家都是这样。
