Build Instructions (Windows)
Follow the guidelines below for building Electron on Windows.
- Windows 7 / Server 2008 R2 or higher
- Visual Studio 2015 Update 3 - download VS 2015 Community Edition for free
- Python 2.7
If you don't currently have a Windows installation, dev.microsoftedge.com has timebombed versions of Windows that you can use to build Electron.
Building Electron is done entirely with command-line scripts and cannot be done with Visual Studio. You can develop Electron with any editor but support for building with Visual Studio will come in the future.
Note: Even though Visual Studio is not used for building, it's still required because we need the build toolchains it provides.
Getting the Code
$ git clone https://github.com/electron/electron.git
The bootstrap script will download all necessary build dependencies and create
the build project files. Notice that we're using
ninja to build Electron so
there is no Visual Studio project generated.
$ cd electron $ python script\bootstrap.py -v
Build both Release and Debug targets:
$ python script\build.py
You can also only build the Debug target:
$ python script\build.py -c D
After building is done, you can find
target) or under
out\R (release target).
To build for the 32bit target, you need to pass
running the bootstrap script:
$ python script\bootstrap.py -v --target_arch=ia32
The other building steps are exactly the same.
Visual Studio project
To generate a Visual Studio project, you can pass the
$ python script\bootstrap.py --msvs
To clean the build files:
$ npm run clean
See Build System Overview: Tests
Command xxxx not found
If you encountered an error like
Command xxxx not found, you may try to use
VS2015 Command Prompt console to execute the build scripts.
Fatal internal compiler error: C1001
Make sure you have the latest Visual Studio update installed.
Assertion failed: ((handle))->activecnt >= 0
If building under Cygwin, you may see
bootstrap.py failed with following
Assertion failed: ((handle))->activecnt >= 0, file src\win\pipe.c, line 1430 Traceback (most recent call last): File "script/bootstrap.py", line 87, in <module> sys.exit(main()) File "script/bootstrap.py", line 22, in main update_node_modules('.')

This is caused by a bug when using Cygwin Python and Win32 Node together. The
solution is to use the Win32 Python to execute the bootstrap script (assuming
you have installed Python under
$ /cygdrive/c/Python27/python.exe script/bootstrap.py
LNK1181: cannot open input file 'kernel32.lib'
Try reinstalling 32bit Node.js.
Error: ENOENT, stat 'C:\Users\USERNAME\AppData\Roaming\npm'
Simply making that directory should fix the problem:
$ mkdir ~\AppData\Roaming\npm
node-gyp is not recognized as an internal or external command
You may get this error if you are using Git Bash for building, you should use PowerShell or VS2015 Command Prompt instead.
