I'm not very familiar with webpack, so there may be missing fixes.

Switching project build to vue-cli 4 may come first

@nsano-rururu merged already! Thanks, but I think most of the babel plugins included are unnecessary

@nsano-rururu I have a bad news here, these days I found that the vue2 branch has some problem. (vue3 branch is okay)

I get Error: Can't find intersection (probably https://github.com/babel/minify/issues/904) in terminal each time I modify src/At.vue

If I tried to revert recent merged PRs, it will work again -- try-to-fix-webpack-reload (w/ old deps requires node<=14.x, or you can optionally upgrade sass and sass-loader and use node>=14.x)

Seems this #138 PR introduced the problem I meet, do you have the same problem?

@fritx

I didn't notice the problem because I wasn't using the OSS I maintain with the version that pulled in 138 pull requests. Since I was using 2.5.0-beta.2. . .

@nsano-rururu never mind. The users won't be affected. It's just a local developing issue (the webpack reload breaks) I've recently met. I'm not sure if you guys are also coming across it.

The error looks like:
