"API fatal error handler returned after process out of memory on the background thread" 在构建 angular 电子应用程序时

Question

我们正在使用 angular 10.2、electron 4.2、electron-builder 22.9 和节点 10.16.0。此外，每次发出 Pull 请求时，我们都会执行一个 jenkins 管道。此管道创建一个 AWS windows 实例 (t2.large) 以下载代码并构建一个 .exe 文件。问题是编译代码时，弹出此错误： Fatal error # API fatal error handler returned after process out of memory on the background thread.

节点变量--max_old_space_size value is 4191.868721008301 MB。如果手动启动 AWS windows 实例，运行 npm install 并手动构建代码，没有错误被触发并且构建完全成功。该错误仅在以下情况发生 jenkins 启动 AWS windows 实例。

在 --max_old_space_size=1.5GB 的 mac 环境中，构建过程完全成功。同样，当在 windows 和 --max_old_space_size=1.5GB 中手动测试时，构建也很好。如果变量设置为 --max_old_space_size=512MB 构建失败并出现不同的错误 Javascript 堆内存不足。

我猜是不是与 jenkins 线程内存有关？但我还没有找到如何增加线程内存。

任何想法，提示都会有所帮助。

        deleteDir()

        checkout scm

        bat """
        cd app
        call npm run node-memory
        call node -v
        call npm --no-git-tag-version version \"${version}\"
        call npm install
        REM call npm run test - tests disabled on Windows for now (they run on Mac OS)
        call npm run build"""
    }
}

Package.json 构建脚本： "build": "npm run download-translations && ng build --prod && electron-webpack && electron-builder --publish=never",

由于这个问题从 angular 9 and 10 as well 开始，我们创建了一个 linux slave 来执行构建过程，然后在 mac 和 windows slaves 中存储文件和取消存储.

node('nvm-slave') {
        // Wipe the workspace so we are building completely clean
        deleteDir()

        checkout scm

        nvm(nvmInstallURL: 'https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh', nvmIoJsOrgMirror: 'https://iojs.org/dist', nvmNodeJsOrgMirror: 'https://nodejs.org/dist', version: '10.16.0') {
            sh '''cd app
            npm install
            npx ng build --prod
            '''
        }

        stash name: "folder-to-stash", includes: "path/to/folder/to/stash/**"
}

stage ('Build Windows app') {
    node('windows-electron') {
        // Wipe the workspace so we are building completely clean
        deleteDir()

        checkout scm

        unstash "folder-to-stash"

        bat """
        cd app
        call node -v
        call npm --no-git-tag-version version \"${version}\"
        call npm install
        REM call npm run test - tests disabled on Windows for now (they run on Mac OS)
        call npm run postbuild"""

        archiveArtifacts 'app/dist/*.exe'
    }
}

Package.json 脚本：

"build": "ng build --prod",
"postbuild": "electron-webpack && electron-builder --x64 --publish=never",
