npm install works but npm prune throws "Error: Cannot find module 'klaw'"

[awayken]

I'm using PhantomJS with PhantomCSS. With the release of npm5, I decided to go through and update my projects. With this particular project, npm install works just fine. Here is my output:

C:\Sites\acx\vertical_responsive [feature/npm5 +0 ~2 -0]> npm install

But, if I run npm prune, PhantomJS throws an error:

This could be some sort of bug in npm, but I'm starting here. Any ideas? What information do you need from me?

I just tried to install a new package to my project, and I got the klaw error above.

C:\Sites\acx\vertical_responsive [feature/npm5 +0 ~2 -0]> npm install gulp-imagemin

I'm really not sure why PhantomJS is involved in this install command. It's already installed without issue.

Hello,

I noticed the exact same behavior, using NPM5, npm prune && npm i is failing with the same error.

Any idea?

Got the same error while trying to install the express-winston library. Is there any solution ?

[bichotll]

Got the same problem using https://github.com/saguijs/sagui

I should say that I've since reverted to npm4, and I didn't have these same issues. Even more recently, I've been using Yarn almost exclusively, and I don't see this issue. It very much seems to be a bug of some sort in npm5.

I'm also having this now.

Steps that I followed: npm install --save react-native-push-notification react-native link <<<------- this triggers the error

This is my config: "react": "16.0.0-alpha.12", "react-native": "^0.46.4",

npm -v 5.0.3

Adding fs.extra solved the problem for me. in package.json : "fs.extra": "^1.3.2"
