本地gulp安装后缺少node_modules

Question

I ran into an issue today mid-class. I was showing my class how to install and use gulp.js, so I had to show the process on a projector.

I've installed node.js and gulp.js globally with npm install -g gulp and it all works fine.

But when I try to install gulp locally in the project folder I am working on, it looks like gulp is installed, but the node_modules folder is never created.

I tried refreshing, I tried running the command prompt as admin, I've checked for hidden folders, nothing works. --- I even restarted and tried again, cause Windows.

I am working on windows 10.

Transcript of command line output:

Note: npm is in my PATH.

Answer 1

You need either package.json or folder named node_modules in the current directory. If you are not going to have one, npm will look for either one in the parent directories. Check answer to NPM Installs Package Outside Current Directory for more details.

Also it is advised to start with npm init which will create package.json for you.
