While trying to install karma, npm fails with the error shasum check failed for ... (some path). It is not the same place every time, but it is always "around" the package nan or zeparser.
shasum check failed for ... (some path)
I created this gist with the full output: https://gist.github.com/bendiksolheim/6726702
I can provide the debug log if necessary, but it does not seem to include any more information about this issue.
It does not appear to be a network issue, as this works on my Mac on the same network. We do have two Windows machines where it is not working. Tried both 32bit version and 64bit version, with the same result.
The weird thing is that this did work about a week ago. I have not upgraded node or npm since then, but it could be that the OS has been upgraded in the meantime.
