"TypeError: Path must be a string" after break from project #2463

kingscott · 2016-05-10T00:48:55Z

I updated packages and all seemed fine. I took a week break from the project, ran npm install and cannot seem to figure out the cause of this error. It's on this repo.

For convenience here is the error message and specs:

ERROR in ./src/app.js

and my packages:

    "webpack": "^1.13.0",

If you check out the repo, you can see my server.js and webpack.config.js.

Thanks.

Could you try upgrading to standard 7? Feels like a standard related bug to me.

kingscott · 2016-05-10T03:54:30Z

The error persists. I've swapped out some of my code (new build processes for old etc), updated/downgraded packages. And not sure what it is.

bebraw · 2016-05-10T03:57:34Z

Ok. The next step would be digging into ESLint. Maybe logging near the offending line would give better insight. It might stem from standard-loader configuration somehow so that's another place to inspect.

kingscott · 2016-05-10T04:31:24Z

Hmm, we'd have to dig into ESLint even if I'm not explicitly using ESLint?

bebraw · 2016-05-10T05:34:45Z

See processText at the trace.

bebraw · 2016-05-10T05:58:11Z

What command do I have to run to repro? I tried a few, no luck. I see

ERROR in ./src/app.js
Module not found: Error: Cannot resolve 'file' or 'directory' ../backgrounds.js in ../king/src
 @ ./src/app.js 25:21-49

though.

kingscott · 2016-05-10T13:31:07Z

I can include that file. I excluded it from source control and would prefer to have it not on GitHub. I can email you the file, and then you would just checkout the nasa-update branch and run:

➜  ~  npm install
➜  ~  npm start

bebraw · 2016-05-10T13:37:25Z

Works for me.

king [nasa-update] $ npm start

Maybe I'm missing something. Running on OS X so that could be it. There's some difference.

kingscott · 2016-05-10T13:40:35Z

If you navigate to localhost:2020 what do you get?

bebraw · 2016-05-10T13:40:57Z

It shows some photo background and time(?) then.

kingscott · 2016-05-10T13:44:40Z

Hmm weird. I was getting the same error on OS X as well as Linux.

bebraw · 2016-05-10T13:47:26Z

It's really hard for me to say anything concrete. You would have to look at the stack trace and go from there. Perhaps someone else can repro.

In any case, this might fit Stack Overflow better as it seems the issue is somewhere else than webpack core.

kingscott · 2016-05-10T13:49:22Z

I am slightly confused as to why you cannot replicate the bug, what version of node and npm are you running?

bebraw · 2016-05-10T13:51:01Z

king [nasa-update] $ node -v
v5.10.1
king [nasa-update] $ npm -v
3.8.3

bebraw · 2016-05-10T13:51:36Z

I've seen some weird Node 6 reports so maybe that's it?

kingscott · 2016-05-10T13:53:58Z

Must be a node problem. Downgraded to node 5.11.1 and it works. Thanks for the help, you can close.

👍

bebraw · 2016-05-10T13:55:20Z

Ok. You could consider reporting this upstream to standard-loader.

kingscott · 2016-05-10T13:55:44Z

I'll give it a shot, thanks @bebraw.

felix-d · 2016-05-15T18:57:35Z

Had the same issue and no stack trace to help me debug this whatsoever. Downgraded from node 6 to 5 and... success! Thanks!

wiiiim · 2016-05-15T22:14:58Z

same here 👍

kingscott · 2016-05-15T22:26:22Z

Hey @felix-d @wiiiim, this helped me in the end!

Cheers!

JohnnyMa · 2016-06-04T07:11:43Z

Great! It helps me to resolve the same issue. Thanks! 👍

jkomyno · 2016-06-08T21:15:07Z

Thank you guys!

yarhtut · 2016-06-26T01:04:03Z

Thanks you guys

dace · 2016-07-09T06:21:42Z

Yeah, downgraded from Node 6.2 to 5.12 and this resolved the issue for me. Thanks!!

jcubic · 2016-10-20T08:12:52Z

@binarious did you try to update node-sass or sass-loader?

binarious · 2016-10-20T08:14:35Z

@jcubic both are at their latest versions.

binarious · 2016-10-20T08:36:13Z

Seems to be a bug somewhere else: webpack-contrib/sass-loader#285

ximet · 2016-11-05T09:39:28Z

I have the same problem. Env: node.js version: 7, "webpack": "1.13.3", "babel-loader": "6.2.7", "react-hot-loader": "1.3.0", "babel-core": "6.18.2". Other loader is missing.

flyskywhy · 2016-11-25T01:58:27Z

This issue is resolve in taofed/react-web#136 :

use node 5.x instead of node 6

or

add a key 'publicPath' to the webpack config output node

output:{
    publicPath:''
}

bolivar · 2017-01-25T14:50:09Z

Upgrading npm solved my problem but thanks a lot guys!!!

bpartridge · 2017-02-28T20:39:45Z

For anyone who hasn't upgraded NPM recently, use npm install -g npm per @bolivar's suggestion.

ehsankhf · 2017-03-08T08:49:58Z

Webpack update was the perfect solution for this issue. I'd like just to add a comment on how to update the npm packages easier. You'd need to run the following three commands in your project's root directory:

npm i -g npm-check-updates
npm-check-updates -u
npm install

ruoru · 2017-06-27T07:06:38Z

i meet the same question

➜  ~ node -v
v8.1.0
➜  ~ npm -v
5.0.4

the error message

ERROR in ./app/index.js
Module build failed: TypeError: Path must be a string. Received undefined

and i update my babel-core version to 6.11.4, it`s work well
@yorkie Great! It helps me.

29er · 2017-07-11T03:11:03Z

I had to downgrade to node 6.11 ( I was on 8 ) and upgrade to babel-core to 6.11.4 and it worked.
doing one or the other did NOT work. FYI

greygatch · 2017-07-27T16:56:05Z

Had to downgrade to node v5.12 and babel-core is at v6.25.

Annoying that I can't even use the LTS version of Node.

Pie4kaiz · 2017-08-10T08:31:36Z

I got it working now after using ncu (npm-check-updates) to fetch the latest versions:

react-redux          ^5.0.5  →  ^5.0.6
eslint-plugin-react  ^7.1.0  →  ^7.2.0
webpack              ^3.5.1  →  ^3.5.2
webpack-dev-server   ^2.7.0  →  ^2.7.1

Node: v8.2.1
NPM: 5.3.0

pkerpedjiev · 2018-09-05T18:03:31Z

I get this error using:

NPM: 5.6.0
NODE: 9.9.0
webpack-dev-server: 2.6.1

It disappears if I remove the devtool: 'cheap-source-map' option from my webpack.config.js.
