`analyzerMode: 'static'` doesn't seem to be working anymore.

Issue description

analyzerMode: 'static' doesn't seem to be working anymore. No report file is generated and the web server is started.

Technical info

• Webpack Bundle Analyzer version: 3.8.0
• Webpack version: 4.43.0
• Node.js version: 14.0.0
• npm/yarn version: 16.14.5
• OS: Ubuntu 19.10

Debug info

How do you use this module? As CLI utility or as plugin?

Plugin

If CLI, what command was used? (e.g. webpack-bundle-analyzer -O path/to/stats.json)

If plugin, what options were provided? (e.g. new BundleAnalyzerPlugin({ analyzerMode: 'disabled', generateStatsFile: true }))

new BundleAnalyzerPlugin({ analyzerMode: 'static'})

What other Webpack plugins were used?

• CleanWebpackPlugin
• HtmlWebpackPlugin
• Dotenv

It would be nice to also attach webpack stats file. It can be generated using these options:

new BundleAnalyzerPlugin({
  analyzerMode: 'disabled',
  generateStatsFile: true,
  // Excludes module sources from stats file so there won't be any sensitive data
  statsOptions: { source: false }
})

stats.json will be created in Webpack bundle output directory.

Can you test which earlier version of webpack-bundle-analyzer does work for you?

Same issue here. Downgrading to 3.7 and 3.6 didn't work either. I'm running the build with webpack-dev-server.

After some debugging, I don't know it this is a regression issue but what I saw is this:

viewer.js

          fs.writeFileSync(reportFilepath, reportHtml);

I think this is not supposed to work with webpack-dev-server, right? Is webpack-bundle-analyzer only emitting files with the fs module? Isn't it a webpack plugin api for emitting files to the output directory? (for loaders, I known at least there is this.emitFile) I'm using webpack-bundle-analyzer as a plugin like this:

const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;

const webpackConfig = {
    //...
    plugins: [
        //...
        new BundleAnalyzerPlugin({
          analyzerMode: 'static',
          openAnalyzer: false,
        }),
    ]
}

So the question is:

• Can this plugin work with webpack-dev-server (with ram files) or only with webpack cli?
• If it can, then how? Am I missing docs with specific instructions somewhere?

• Can this plugin work with webpack-dev-server (with ram files) or only with webpack cli?

No, it can't work with WBA (virtual file system).

@yursha does this issue still valid? I so, could you please create a reproduction repo.

Closing as there hasn't been a reproduction.
