webpack: [webpack-cli] TypeError: cli.isMultipleCompiler is not a function

I’m getting TypeError: cli.isMultipleCompiler is not a function when running an app via docker. The node modules are installed, I’m using

"webpack": "5.72.1",
"webpack-cli": "4.9.2",
"webpack-dev-server": "4.8.0"

Any ideas what could be causing it?

Here’s the full error

Please upgrade to the latest version of webpack-cli that is 4.10.0

Duplicate of https://github.com/webpack/webpack-cli/issues/3294, fix is-

   "webpack": "5.72.1",
-  "webpack-cli": "4.9.2",
+  "webpack-cli": "4.10.0", 
   "webpack-dev-server": "4.8.0"

Found the answer! Here is how you update your webpack-cli for anyone else who was curious.

First, check your version of webpack by running this command in the terminal of your IDE: webpack --version. You should see a list that appears like this: webpack: 5.71.0 webpack-cli: 4.10.0
webpack-dev-server 4.8.0

If your webpack-cli reads anything below 4.10.0, then you need to update it to the latest version for npm to run properly on your localhost with JHipster. Here’s how to update it.

Run this command in the terminal of your IDE: npm install webpack-cli@4.10.0

[Right now, the latest version is 4.10.0, but for the future updates when you run this command, change the version at the end of the command line to updated to that current version: npm install webpack-cli@(INSERT NEW VERSION DIGITS HERE).

Then re-run webpack --version, and see if your webpack has updated to the version that you entered above.


EXTRA NOTES:

Why did you have this error? According to webpack.js.org: “Note that this is not a recommended practice. Installing globally locks you down to a specific version of webpack and could fail in projects that use a different version.”

So, if you ran a command like this: npm install --global webpack, then there is a good chance that you were locked down to a specific version. This might have been the error. That’s what I believe happened to me anyway. I ran npm install -g, or something of that nature.

Hope this helps! Best of blessings to ya!
