There is a branch without-e2e-cypress, the cli-service work fine on serve and build.

[duduluu]

This only happens when the project is in workspaces.

Some times it will Error: Cannot find module '@babel/parser', it may be about other plugins, but I cannot reproduce at present.

Duplicate of #2599
As a workaround you can manually add babel-loader to your dependencies.

[duduluu]

It resolved.
But there is another error about PostCSS Config.
@sodatea

[haoqunjiang]

Thanks for your report. I think it's also been reported before #2572

[haoqunjiang]

The two issues can be solved by adding these lines to vue.config.js:

const path = require('path')

module.exports = {
  css: {
    loaderOptions: {
      postcss: {
        path: __dirname
      }
    }
  },
  chainWebpack: config =>
    config.resolveLoader.modules.add(
      `${path.dirname(require.resolve('@vue/cli-plugin-babel'))}/node_modules`
    )
}

[haoqunjiang]

Update: the original module path is wrong, I've updated it in the previous comment (should wrap the require.resolve call with path.dirname).

super thx
