Running in Windows 7 Enterpise with administrator right

[rwz]

I do not own a Windows machine and can't fix this issue. Any help here would be welcome.

[nruth]

http://www.ember-cli.com/#symlinks-on-windows says it's an access control policy issue, i.e. run as admin, or failing that have the plugin fall back on copying files when symlinking isn't available.

[rwz]

@nruth this issue has nothing to do with ember-cli

[swelham]

The issue here is that windows doesn't support symlinks in the same way. See my PR #136 which solves this issue (based on my tests) using the mklink windows command.

[nruth]

@rwz OK, I'll leave you to it then.

[rwz]

I can create a branch and start working on windows support. However I need people to voluntarily help me testing it since I don't own a Windows machine.

[JanJacobs]

I want to volunteer for testing on Windows.

I am currently using it and had to make changes to ember-cli-rails-0.3.5 to make it work on Windows.

I had to implement #114 with a change to ember-cli\app_win.rb
OLD:

@ember_path ||= app_path.join

NEW:

ember_path ||= Rails.root.join

I also had change to the ember-cli\runner.rb because Process.getpgid is not supported on Windows.
OLD:

    def still_running?
      Process.getpgid app.pid
      true
    rescue Errno::ESRCH # no such process
      false
    end

NEW:

   def still_running?
      Process.kill 0, app.pid
      true
    rescue TypError #Errno::ESRCH - no such process, Errne::EPERM
      false
    end

We're sorry that this issue has sat for so long.

The project is now maintained by thoughtbot, and we're declaring an issue bankruptcy of sorts.

We're closing this issue. If what you've described is still a problem, please comment on this issue and we'll reopen.

@JanJacobs those changes look promising, would you mind opening a PR to help with windows support?

Thanks for your patience.

👍 Still have this problem on windows 7 using Rails 4.2.4 and ember-cli-rails 0.5.3 with corresponding ember-cli-rails-addon
