Webpack adding duplicates of runtime into bundle

问题

Does anyone know why I am getting duplicates of the webpack runtimes in the bundle?

It's adding multiple numbers after the ? and the browser is seeing them as new files.

• dev-server.js?
• dev-server.js?52d4
• dev-server.js?53d4*

See the file tree on the left:

Why is it doing this? I just want one copy of the file in the bundle.

回答1:

Webpack sets up a client/server pair for each entry by design. That's why you are seeing all of those prints. Given each entry happens to depend on jwt-decode, you also get those warnings.

Here's the relevant code. The code was introduced as a part of a bug fix.
