Yeoman error: "Errno::EACCES on line ["897"] of C: Permission denied"

Question

I upgraded my hardware yesterday and fresh installed Win 8.1. This error is killing me since then. I already lost full day of work trying to figure out what's going on. I never encountered this on my Mac or in my old Win 7 machine.

Setting up a new project with yo webapp using Bootstrap and Modernizr works great. Server would fire-up and I can see my updates livereload. But, setting up a new project with Compass and SASS included would prevent me from starting local server and throw this error:

D:\test>grunt serve
Running "serve" task

Running "clean:server" (clean) task

Running "concurrent:server" (concurrent) task

Running "copy:styles" (copy) task

Done, without errors.

I updated Compass and SASS to latest version, reinstalled Yeoman & Ruby, and tried bunch of other small tweaks. Nothing worked.

Any ideas what else I could try?

Answer 1

I have found solution for this issue. I guess this might help with other similar problems running grunt server. This is what did it for me:

Uninstall SASS

gem uninstall sass

Uninstall COMPASS

gem uninstall compass

Install --pre COMPASS version

gem install compass --pre

Install --pre SASS version

gem install sass --pre

For some reason only running task in this order worked for me. I hope this helps.

Answer 2

Issue is solved in SASS 3.2.19 Try gem update compass
