Build errors on Windows, v1.1.4 not on npm

[vlascik]

v1.1.4 is not on npm, so the build still breaks on Windows, probably because of missing fix that was merged after 1.1.3.
Build then breaks on 1.1.4 if \tmp folder already exists, so it has to be deleted manually before each build, error is:

EEXIST: file already exists, mkdir 'C:\Project\tmp'

After publishing v1.1.5 on npm we've got this problem (i suppose this should be not only ours problem) when we trying to create new ember application via ember init command (ember application uses ember-cli and ember-cli-qunit which are depends on last version of symlinc-or-copy).
So after creating a new ember application most ember commands fails with above-described error.
Will this problem be fixed?

we are facing a similar problem and expecting urgent fix asap.

@feanor07 @ehaberev actually your bug is the result of the fix for this issue.

[stefanpenner]

this was momentarily released, but had to be reverted do to: ember-cli/ember-cli#6156

We will need to investigate why + fix before we can release again
