Since the commit [Use Yarn to manage dependencies, cleanup unused bootstrap libs (#6436) · discourse/discourse@dc8a16b · GitHub](https://github.com/discourse/discourse/commit/dc8a16b43bf264b9001e3515aaba9dc9d5143228), running `npm install` fails.
Looking at the log file …
```plaintext
880 silly fetchPackageMetaData error for jquery.autoellipsis@git+https://github.com/pvdspek/jquery.autoellipsis.git premature close
881 silly fetchPackageMetaData error for favcount@git+https://github.com/chrishunt/favcount.git premature close
882 silly fetchPackageMetaData error for jquery-resize@git+https://github.com/cowboy/jquery-resize.git premature close
```
… installation fails for dependencies whose version is a git repository instead of a semantic version string. In particular, they fail if in the repostitory, there is no `package.json` file.
Discourse’s dependencies from `package.json`:
```json
"dependencies": {
"ace-builds": "1.4.1",
"bootbox": "3.2.0",
"chart.js": "2.7.2",
"favcount": "https://github.com/chrishunt/favcount",
"handlebars": "4.0.5",
"htmlparser": "https://github.com/tautologistics/node-htmlparser",
"jquery": "3.3.1",
"jquery-color": "1.0.0",
"jquery-resize": "https://github.com/cowboy/jquery-resize/",
"jquery.autoellipsis": "https://github.com/pvdspek/jquery.autoellipsis",
"jquery.cookie": "1.4.1",
"jquery-tags-input": "1.3.5",
"magnific-popup": "1.1.0",

"pikaday": "1.7.0",
"resumablejs": "1.1.0",
"spectrum-colorpicker": "1.8.0"
}
```
Is `npm install` still supposed to work or is Yarn the only option here?

This is a development question, not an install question, yes?

Is it? I wasn’t quite sure. Are these dependencies only relevant for Discourse’s testing? Then the category was wrong indeed. Sorry about that.

@pmusaraj any tips here? Also … why are you using npm, we only really test using yarn and only support yarn for dev.

I think the error you’re getting is due to our `package.json` using yarn syntax for referencing Github versions of dependencies. So, use `yarn install` instead of npm. Also, `yarn install` is only required for running frontend (qunit) tests or when a developer is upgrading one of the Discourse dependencies listed in `package.json`.

I wonder if there is some entry we can add to our `package.json` that would force `npm install` to explode with a “sorry, npm is not supported use yarn”
Ultra low priority though.

@pmusaraj that seems like a good track to follow:

I did not know that only Yarn is supposed to be used here. I saw a package.json and run `npm install` a short while ago to run my plugin tests. Now, `npm install` doesn’t work.
~~It looks like Yarn and NPM use incompatible syntax for referencing remote git repositories via URL so there is no nice common ground.~~
Yarn does seem to support this as per [git+ssh install protocol is not used correctly · Issue #2500 · yarnpkg/yarn · GitHub](https://github.com/yarnpkg/yarn/issues/2500)
However, the missing package.json in these repositories makes npm fail.

@kleinfreund there is absolutely no need to run `npm install`. And as Sam and Joffrey point out, we will shortly block running `npm install` on the repo. (Just use `yarn install`.)

I get it. It’s just that I didn’t previously need Yarn, so I have to install it. That’s not a big deal though.

This commit adds a preinstall hook that stops `npm install` and outputs “NPM is not supported, please use Yarn instead.” to the user.
