简而言之…

首先，为什么npm建议仅以非root用户身份运行它？我不相信高，每一个其他的包管理器（apt，yum，gem，pacman）是错误的，需要sudo的。

其次，当我遵循他们的建议（并npm install以非超级用户身份运行）时，它将不起作用（因为非超级用户没有对/ usr / local /
lib的许可）。我如何遵循他们的建议？我不会去chown -R $USER /usr/local/lib，因为这对我来说似乎是个坏主意。

详细描述…

我通过（自述文件中的说明）安装了npmcurl http://npmjs.org/install.sh | sudo sh。

当我运行时sudo npm install mongoose，npm告诉我不要以root身份运行它：

npm ERR! sudon't!
npm ERR! sudon't! Running npm as root is not recommended!
npm ERR! sudon't! Seriously, don't do this!
npm ERR! sudon't!

但是当我npm install mongoose不使用sudo 运行时，我得到以下信息：

npm info it worked if it ends with ok
npm info using npm@0.2.17
npm info using node@v0.4.0-pre
npm info fetch http://registry.npmjs.org/mongoose/-/mongoose-1.0.7.tgz

npm not ok

因此它告诉我我不应该使用sudo，如果我遵循他们的建议，那么它就不起作用。

这导致了我上面的最初问题。
