NPM不会安装哈巴狗吗？

Question

Can anyone help me decipher what this message is about? I have another app with pug installed, yet now I cannot create a new module installation for some reason.

I'm installing pug local to the app into node_modules

I'm just trying to get work done, so if I have missed something simple, my stress level has not been helpful with keeping precise vision.

My system is for ongoing development so I don't muck around with upgrades, which historically has broken all kinds of other stuff.

My other app works fine.

# npm install --save pug@2.0.0-beta4 <= Because the working app uses this one

Answer 1

You may need to install using sudo, ie - sudo npm install ... . This will prompt you for your root password.

It looks like root privileges are required to install the package you're looking for. Though this shouldn't really be the case, you can fix this.... check out this link

Answer 2

After some prodding by @zillaofthegods, it turns out some of directories in ~/.npm were owned by root. In particular the wordwrap module directory.

Changed the permissions and npm installed it fine.

One of those things I would not have caught without some prodding, so thanks.
