Webpack-dev-server: Webpack peer dependency 1.3 or higher yet there is no webpack version 1.3

Created on 18 Dec 2015 · 40Comments · Source: webpack/webpack-dev-server

Hi,

I see that there is a peer dependency to require webpack 1.3 or higher that has been checked in for over a year.
"webpack": ">=1.3.0 <3"

As far as I can tell, there is no webpack version 1.3 as the highest is 1.12.9.
Can this peer dependency version be fixed so it does not require a non-existent version?

It is causing these warnings when I install:
angular2-webpack-starter$ npm install --global webpack-dev-server
/Users/beyondenergy/.npm-packages/bin/webpack-dev-server -> /Users/beyondenergy/.npm-packages/lib/node_modules/webpack-dev-server/bin/webpack-dev-server.js
/Users/beyondenergy/.npm-packages/lib
├── UNMET PEER DEPENDENCY webpack@>=1.3.0 <3
└─┬ [email protected]
└── UNMET PEER DEPENDENCY webpack@>=1.0.0 <3

npm WARN EPEERINVALID [email protected] requires a peer of webpack@>=1.3.0 <3 but none was installed.
npm WARN EPEERINVALID [email protected] requires a peer of webpack@>=1.0.0 <3 but none was installed.

I think the solution is to install both webpack and webpack-dev-server at the same time. If you already have webpack installed, you don't need to uninstall it first. This was the solution for me.

npm install --global webpack webpack-dev-server

I'm also receiving this error, Would this cause an internal issues with webpack?

Same issue and solved.
It's not about the version, just DO NOT use -g or --global, and install it into local project, it works.
Though I still want to install it globally...

It looks like the version of webpack that is installed by npm by default is too old and doesn't meet the version requirements (webpack@>=1.0.0 <3). Omitting -g has no effect for me.

Peer Dependencies are no longer implicitly install as of node 5 check here. The latest version is Webpack is being installed through the devDependences. The peerDependencies code in package.json just hasn't been removed yet.

Thanks @lenell16. So if:

[t]his shifts the responsibility for fulfilling peer dependencies from library / framework / plugin maintainers to application authors

Shouldn't the latest version of webpack and webpack-dev-server just install with the basic install commands on the latest node and npm versions, and the beta non-resolving libraries be for edge developers?

For example using node 5.6.0 and npm 3.6.0 and run npm install webpack webpack-dev-server --save-dev on a brand new project I get unmet dependency errors.

Updates package.json:

  "devDependencies": {
    "webpack": "^2.1.0-beta.1",   // If I set this manually to the latest non-beta tag
                                  // "^1.12.13" it works fine.
    "webpack-dev-server": "^1.14.1"
  }

And gives the following npm console output:

Same here...Ubuntu 14.04.3 LTS...

Same here using npm 3.6.0 and node 5.7.1

douglascorrea on 16 Mar 2016

+1 on this issue! Got the same problem on the stable versions using the -g flags, without those it seem to work.

Using: webpack 1.12.14
and webpack-dev-server: 1.14.1

Can't use this combination global even though they are the last stable releases. Which seems to me like a bug, or should be explained somewhere if there is a reason why it cannot be used global.

cablegunmaster on 22 Mar 2016

Same issue here.
For betas it's because webpack@>=2.0.3-beta resolves to webpack@^1.12.14 and etc. Looks like an old bug in npm. Even there http://semver.npmjs.com/ it just gives no results. Funny, but e.g. >=1.0.0-beta1 works fine.
Interested in beta (e.g. @mummybot) you should try this commit (isn't released at the moment) https://github.com/webpack/webpack-dev-server/commit/202165717b974392c3048e52fad1e83468129438. It works.

I was having the same issue, and came across this other closed PR (https://github.com/webpack/webpack-dev-server/issues/429). Not quite expert-level enough to say why this works, but it does. Possibly it's because my global npm dir has always been ~/.npm (back long before npm was 3.x when they changed some dependency management)??

bigdawggi on 28 Mar 2016

+1 No error installing it locally, but globally.
webpack version is 1.12.14, though npm install -g webpack-dev-server tells

/usr/local/bin/webpack-dev-server -> /usr/local/lib/node_modules/webpack-dev-server/bin/webpack-dev-server.js

Fix:

$ npm install -g webpack
$ npm install -g webpack-dev-server    <- will error
$ webpack-dev-server                   <- seems to work fine reguardless

Nice link to http://semver.npmjs.com/ @arantir ! The reason >=1.0.0-beta1 works fine is that it is excluding the offending beta tag 2.0.0-beta, not sure why given there is no ^ to fix it to the major versions and 2 is greater than 1.

Generally I am not keen on installing webpack and webpack-dev-server globally. IMHO it is better to have all environmental packages included as part of a project so that setup for different developers is a known quantity.

My question to the webpack-dev-server dev contributors: why the have published the beta as the latest tag on npm such that npm install webpack-dev-server installs this rather than the latest stable release 1.14.1?

I think the solution is to install both webpack and webpack-dev-server at the same time. If you already have webpack installed, you don't need to uninstall it first. This was the solution for me.

npm install --global webpack webpack-dev-server

@janaagaard75 That suppressed the warning, but did not resolve the version missmatch. You'll get the same result installing them seperately, only diff is the warning.

Same issue here. Ubuntu 16.04, Nodejs v4.2.6, Npm v3.5.2.

Weirdly enough it works in Win7 just fine.
node 6.2.1
npm 3.9.3

So, what the heck is wrong with webpack? is this a zombie project or how come no one from the contributors seem to comment about getting it fixed?

Having the same problem

Fixed my my problem. I was using fish in my command line shell with webstorm after removing it all seems to work fine but not quite sure why. But I hope this helps someone.

I was able to fix this problem by installing the last version of webpack as a dev dependency too.

$ npm install [email protected] --save-dev

Dupe of #363.

SpaceK33z on 21 Aug 2016

For me, the update of npm solved:
sudo npm install -g npm

@Ahren110, your errors are not relevant to this specific issue, it's about npm problem. See https://github.com/npm/registry/issues/255 for reference

yrtimiD on 6 Jan 2018

This is my solution. Install 3 packages together.

npm install -g webpack webpack-dev-server webpack-cli

No @bakkujp , it doesn't solve it.
Whenever I try to install " npm install && bower install " , I get this error .
Can anyone please suggest a solution

Hey guys,
I got the same error message. I found this on Stack Overflow, and it works.

run this on the command line --> npm i -D webpack@latest

Here is the solution that worked for me. All too often you either have a hidden dependency issue or in other cases you have a corrupt package/file.

ERROR MESSAGE:
npm WARN [email protected] requires a peer of webpack@^1 || ^2 || ^3 but none is installed. You must install peer dependencies yourself.

SOLUTION 1:

Install NPM check updates module. Note this is a global utility.
sudo npm install -g npm-check-updates
Once install run it
ncu -u
Run npm update
npm update

SOLUTION 2 (not recommended but sometimes it is the only option):
If the problem continues you might have a problem module or a file. In that case I delete the local app node_modules directory and the package-lock.json (NOT!! THE package.json file as you will lose your config). Then run npm install to reinstall modules and dependencies.
