尝试在ubuntu上使用sudo安装elm时出现权限被拒绝错误

Question

我正在尝试在我的机器上安装elm (Ubuntu16.04.2LTS)。

按照该链接上的说明运行$ npm install -g elm，我得到一个权限错误。所以我再次尝试使用sudo，即$ sudo npm install -g elm。

这会产生另一个权限错误，即

$ sudo npm install -g elm

如何继续安装Elm？

Answer 1

理想情况下，/usr/local/lib/node_modules/上的权限是这样的:您不需要根权限就可以在那里安装某些东西。

如果这是不可能的，您需要告诉npm，is不应该删除其根权限(这是一个安全保护，以防止流氓安装脚本以根权限运行)：

$ sudo npm install --unsafe-perm -g elm
