# Build Instructions (Windows)
|
|
|
|
Follow the guidelines below for building Electron on Windows.
|
|
|
|
## Prerequisites
|
|
|
|
* Windows 10 / Server 2012 R2 or higher
|
|
* Visual Studio 2017 15.7.2 or higher - [download VS 2017 Community Edition for
|
|
free](https://www.visualstudio.com/vs/)
|
|
* [Python 2.7.10 or higher](http://www.python.org/download/releases/2.7/)
|
|
* Contrary to the `depot_tools` setup instructions linked below, you will need
|
|
to use your locally installed Python with at least version 2.7.10 (with
|
|
support for TLS 1.2). To do so, make sure that in **PATH**, your locally
|
|
installed Python comes before the `depot_tools` folder. Right now
|
|
`depot_tools` still comes with Python 2.7.6, which will cause the `gclient`
|
|
command to fail (see https://crbug.com/868864).
|
|
* [Python for Windows (pywin32) Extensions](https://pypi.org/project/pywin32/#files)
|
|
is also needed in order to run the build process.
|
|
* [Node.js](https://nodejs.org/download/)
|
|
* [Git](http://git-scm.com)
|
|
* Debugging Tools for Windows of Windows SDK 10.0.15063.468 if you plan on
|
|
creating a full distribution since `symstore.exe` is used for creating a symbol
|
|
store from `.pdb` files.
|
|
* Different versions of the SDK can be installed side by side. To install the
|
|
SDK, open Visual Studio Installer, select
|
|
`Change` → `Individual Components`, scroll down and select the appropriate
|
|
Windows SDK to install. Another option would be to look at the
|
|
[Windows SDK and emulator archive](https://developer.microsoft.com/en-us/windows/downloads/sdk-archive)
|
|
and download the standalone version of the SDK respectively.
|
|
* The SDK Debugging Tools must also be installed. If the Windows 10 SDK was installed
|
|
via the Visual Studio installer, then they can be installed by going to:
|
|
`Control Panel` → `Programs` → `Programs and Features` → Select the "Windows Software Development Kit" →
|
|
`Change` → `Change` → Check "Debugging Tools For Windows" → `Change`.
|
|
Or, you can download the standalone SDK installer and use it to install the Debugging Tools.
|
|
|
|
If you don't currently have a Windows installation,
|
|
[dev.microsoftedge.com](https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/)
|
|
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.
|
|
|
|
## Building
|
|
|
|
See [Build Instructions: GN](build-instructions-gn.md)
|
|
|
|
## 32bit Build
|
|
|
|
To build for the 32bit target, you need to pass `target_cpu = "x86"` as a GN
|
|
arg. You can build the 32bit target alongside the 64bit target by using a
|
|
different output directory for GN, e.g. `out/Release-x86`, with different
|
|
arguments.
|
|
|
|
```powershell
|
|
$ gn gen out/Release-x86 --args="import(\"//electron/build/args/release.gn\") target_cpu=\"x86\""
|
|
```
|
|
|
|
The other building steps are exactly the same.
|
|
|
|
## Visual Studio project
|
|
|
|
To generate a Visual Studio project, you can pass the `--ide=vs2017` parameter
|
|
to `gn gen`:
|
|
|
|
```powershell
|
|
$ gn gen out/Debug --ide=vs2017
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### Command xxxx not found
|
|
|
|
If you encountered an error like `Command xxxx not found`, you may try to use
|
|
the `VS2015 Command Prompt` console to execute the build scripts.
|
|
|
|
### Fatal internal compiler error: C1001
|
|
|
|
Make sure you have the latest Visual Studio update installed.
|
|
|
|
### LNK1181: cannot open input file 'kernel32.lib'
|
|
|
|
Try reinstalling 32bit Node.js.
|
|
|
|
### Error: ENOENT, stat 'C:\Users\USERNAME\AppData\Roaming\npm'
|
|
|
|
Creating that directory [should fix the problem](https://stackoverflow.com/a/25095327/102704):
|
|
|
|
```powershell
|
|
$ 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.
|
|
|
|
### cannot create directory at '...': Filename too long
|
|
|
|
node.js has some [extremely long pathnames](https://github.com/electron/node/tree/electron/deps/npm/node_modules/libnpx/node_modules/yargs/node_modules/read-pkg-up/node_modules/read-pkg/node_modules/load-json-file/node_modules/parse-json/node_modules/error-ex/node_modules/is-arrayish), and by default git on windows doesn't handle long pathnames correctly (even though windows supports them). This should fix it:
|
|
|
|
```sh
|
|
$ git config --system core.longpaths true
|
|
```
|
|
|
|
### error: use of undeclared identifier 'DefaultDelegateCheckMode'
|
|
|
|
This can happen during build, when Debugging Tools for Windows has been installed with Windows Driver Kit. Uninstall Windows Driver Kit and install Debugging Tools with steps described above.
|
|
|
|
### ImportError: No module named win32file
|
|
|
|
Make sure you have installed `pywin32` with `pip install pywin32`.
|
|
|
|
### Build Scripts Hang Until Keypress
|
|
|
|
This bug is a "feature" of Windows' command prompt. It happens when clicking inside the prompt window with
|
|
`QuickEdit` enabled and is intended to allow selecting and copying output text easily.
|
|
Since each accidental click will pause the build process, you might want to disable this
|
|
feature in the command prompt properties.
