Problems running bootstrap.py on Windows

[Tyriar]

I'm trying to build Electron on Windows to investigate #10188 but I'm running into a problem in bootstrap.py. Here's the error:

>python script\bootstrap.py -v

I believe I have all the prerequisites installed:

• Windows 10 version 1703, OS build 15063.540
• Visual Studio Professional 2015 Update 3
  
• Python 2.7.13
• Node.js 7.9.0
• Git 2.13.2.windows.1

@Tyriar I just tried the build instructions and it went smooth on my Win10 box. However, I remember seeing issues like that previously where the bootstrap was not finishing correctly.

My setup:

• Python 2.7
• node.js 6.9.4
• Windows 10 version 1703 OS build 15063.540)
• Visual Studio Community Edition 2015 Update 3 (same version as you)

One downside of #10188 is that I cannot reproduce from the debug version, only the release version...

Same issue here. Same prerequisites.

[DiegoBM]

Same issues here

Anything on this anyone? Completely unable to build electron on windows

@DiegoBM @jcgalindo I had this issue a couple of days ago on Windows, and the issue was actually to do with crazy long filenames which git config --system core.longpaths true fixed for me. Make sure to delete all previously created files from failed bootstrap attempts.

Hope this helps!

[DiegoBM]

Thank you @taha, it was worth the shot, but unfortunately in this case it seems to be something else. I tried what you suggested but I keep getting the same result

[taha]

@DiegoBM can you post your full error here? Possibly the full log till the error happened.

[DiegoBM]

log.txt
By all means, this is the second attempt to build, but I deleted the whole built and run both clean commands before trying your fix

[taha]

Can you attempt bootstraping from a fresh clone of the repo? And possibly post the log here as well.

Running the clean commands doesn't actually clear out the git submodules synced at the beginning of bootstrap.py script. The error your getting is most likely due to something that went wrong during the process of syncing the git submodules, since the files that are missing are in fact in the electron/node repo. The fact that they're missing means that an error stopped git from finishing the update/sync process of the node submodule.

[DiegoBM]

You were absolutely correct @taha, it worked flawlessly on a fresh new clone, after applying your suggestion. You are the man!

P.S: Sorry for the delay to reply, it took a good chunk of time to bootstrap twice (like with zombies, always double check) and confirm successful build
