Additional context

I used the node native module，But it seems to have failed

This is a problem with webpack and private class features in a 3rdparty library you use in your project. (https://github.com/npm/make-fetch-happen/blob/cd1ddb4aa73c44a082d3f1d6076b08534c6d9853/lib/pipeline.js#L6)

I can not help you much with this. Check the following to figure out the solution.
webpack/webpack#10216

Probably similar, not the same, solution required as #1833

Thank you，brother.

It doesn't seem to work ，I spent the whole day with no clue

After all, this problem points to an environment where C++ compilation is not configured correctly
