Subsequent ember fastboot is failing with "directory not empty"

[dustinfarris]

Summary

This does not happen in a fresh app, seems to be specific to my project.

Running ember fastboot multiple times starts failing with this error:

Build successful - 7367ms.

Error: ENOTEMPTY: directory not empty, rmdir '/Users/dustin/Developer/industrymaps-web/dist/node_modules/encoding/'
    at Error (native)

To reproduce (in my project)

• Run ember fastboot
• Visit localhost:3000 in browser
• Stop fastboot server
• Run ember fastboot again

The directory is not always "encoding", but it's the same error each time.

Running rm -rf dist fixes it once, but can be reproduced again by following above steps.

Updated: this seems to be specific to my project

[dustinfarris]

Going to close this until I can do a better job triaging. Possible this stems from one of the addons I have installed.

I'm also having this problem. @dustinfarris Could you share what was the problem for you?

[dustinfarris]

@josemarluedke I was told on Slack that this is a known problem with fastboot. It doesn't seem to affect the production build, just the local server.

Also having this problem, seems like a big enough productivity killer that its worth fixing. I can try to figure out steps to reproduce if no one else has been able to figure out exactly whats causing it.

@dustinfarris Did your slack conversation shed any light on what might be causing this?

[dustinfarris]

I don't remember it well sorry. I think it was some sort of race condition but not sure at all.

ping @tomdale @rwjblue

Looks like this is a duplicate of issue #246

[steveszc]

This can probably be closed again in favor of #246 and #247

[tomdale]

Sorry this is taking so long to fix, we've got some improvements to the overall way the build works that should address this but it's taking longer than I anticipated. Thanks for your patience! I will close this issue in favor of #246.
