Linting in the "preLoader" phase breaks when using Jade templates about webpack HOT 5 CLOSED

If you do exactly the same steps above, but instead of using the latest vue-webpack-template, you use a past version, it will work. As I have done a tiny pull request recently, GitHub automatically created a fork. The master branch of my fork "is 16 commits behind vuejs-templates:master" at this moment. So, in the "steps to reproduce" above, you can simply change vue init call to:

$ vue init jbruni/webpack my-project

Performing the exact same steps, this is the successfull result:

> my-project@ build /home/jbruni/TT/boo/my-project
> rimraf dist && webpack --progress --hide-modules --config build/webpack.prod.conf.js

Hey... I just found that if I remove the preLoaders from webpack.base.conf.js, the result is successful.

And if I add !eslint back to the loaders, I get the linting back, up & running, and the result is also successful.

      {
        test: /\.vue$/,
        loader: 'vue!eslint'
      },
      {
        test: /\.js$/,
        loader: 'babel!eslint',
        exclude: /node_modules/
      },

So, the issue is related to linting in the "preLoader" phase.

I've read the rationale at http://vuejs.github.io/vue-loader/workflow/linting.html, but I will revert bab75ff in my project until this is resolved.

Thank you.

Thanks for the detailed report. So after investigation, this is actually caused by ESLint/espree monkey-patching Acorn (which is in turn depended by Jade)... it has already been fixed in espree and should expect a new patch release any time: eslint/espree#250

[email protected] is out, update your eslint and it should work :)

Indeed. It works now. Great! Thanks.

Meanwhile, I've faced another (unrelated) issue, which made me remove "plugins": ["transform-runtime"] from .babelrc (at least temporarily, while they don't fix it): https://phabricator.babeljs.io/T7127
