构建说明 | Electron
1 下载depot_tools
（1）安装depot_tools用于获取 Chromium 及其依赖项的工具集：地址
WINDOWS
Download the depot_tools bundle and extract it somewhere.
(2)在 Windows 上，您需要设置环境变量 DEPOT_TOOLS_WIN_TOOLCHAIN=0。为此，打开Control Panel→ System and Security→ System→Advanced system settings并添加一个 DEPOT_TOOLS_WIN_TOOLCHAIN值为 的系统变量0。这告诉depot_tools您使用本地安装的 Visual Studio 版本（默认情况下，depot_tools将尝试下载只有 Google 员工才能访问的 Google 内部版本）
(2)depot_tools添加到系统环节变量path
2 下载代码
$ mkdir electron && cd electron
$ gclient config --name "src/electron" --unmanaged https://github.com/electron/electron
$ gclient sync --with_branch_heads --with_tags
# This will take a while, go get a coffee.慢慢等......
git - error: RPC failed; curl 92 HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1) - Stack Overflow
git config --global http.version HTTP/1.1 
git config --global http.postBuffer 524288000
git config --global http.maxRequestBuffer 524288000
git config --global core.compression 0还报错的话：
clone时出现RPC failed； curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errfno 10054
，输入命令行输入输入以下3个命令：
git init
git config http.postBuffer 524288000
git config http.sslVerify "false"如果报错：Hook 'python3 -c 'import os, subprocess; os.chdir(os.path.join("src", "electron")); subprocess.check_call(["python3", "script/lib/npx.py", "yarn@1.15.2", "install", "--frozen-lockfile"])
我重启了一下电脑就好了
3 编译
构建
设置chromium build tools的环境变量
在命令行中输入
cd src
set CHROMIUM_BUILDTOOLS_PATH=%cd%\buildtools生成 Electron 的 Release build 配置
gn gen out/Release --args="import(\"//electron/build/args/release.gn\")"
编译
ninja -C out/Release electron
