As you can see, I actually build several “apps” with one config, and app is an env variable. Interestingly, only one of these variables fail. The only difference I can see is that pdf app uses this file. This makes me wonder if that should be filed against worker-loader, but it is nowhere mentioned in this particular error stack.
The first two lines of call stack are the most interesting ones – as you can see, it actually seemed to jump from one webpack to another, and indeed react-pdf has webpack 3.x in its dependencies. Interestingly, this caused another error:

Now we have a problem in worker-loader instead. Double checked the version and it’s the newest 1.1.1 that should be supporting Webpack 4.x. What’s going on?
What is the expected behavior?
- Webpack should not jump to another copies of itself if found somewhere else in the directory tree (perhaps the issue here is with using symlinks).
- worker-loader should be working okay with Webpack 4.x
Please mention other relevant information such as the browser version, Node.js version, webpack version, and Operating System.
Node.js: 9.x
Webpack:
affected: 4.1.1
not affected: 3.11.0
OS: Windows 10 Spring Creators Update
Easy reproduction: for me it started to happen when I added
MiniCssExtractPlugin(and its loader) in combination withthread-loader.@niieani Try put MiniCssExtractPlugin.loader before thread-loader, it works for me.
I also have this issues when using MiniCssExtractPlugin with HappyPack
Also using MiniCssExtractPlugin with HappyPack, can relate (falling back to not using HappyPack for the time being)
尝试使用这种方式解决了
Exactly the same for me:
use: [ "thread-loader", MiniCssExtractPlugin.loader, "css-loader", "postcss-loader" ]
