Question

我正在执行使用“ npm测试”以打字稿编写的量角器测试用例。现在它不断抛出致命错误：接近堆限制的无效标记压缩-分配失败-JavaScript堆内存不足。有什么办法可以解决它，以及如何调试此类问题。

在Windows 10中运行我的脚本，尝试在package.json的脚本部分内添加--max-old-space-size = 4096，但它不起作用。也可以通过在窗口环境中设置NODE_OPTION来尝试

我的package.json：

{
    "name": "proex",
    "version": "0.0.1",
    "description": "Protractor , Jasmine and typescript",
    "main": "config.js",
    "dependencies": {
        "@types/jasmine": "^2.8.11",
        "@types/node": "^10.12.8",
        "browserstack-local": "^1.3.4",
        "exceljs": "^1.7.0",
        "log4js": "^3.0.6",
        "properties": "^1.2.1",
        "properties-reader": "0.0.16",
        "protractor": "^5.4.1",
        "protractor-fail-fast": "^3.1.0",
        "shelljs": "^0.8.2"
    },
    "devDependencies": {
        "protractor-beautiful-reporter": "^1.2.7"
    },
    "scripts": {
        "pretest": "npm run tsc",
        "test": "protractor ConvertedJSFiles/config.js",
        "tsc": "tsc"
    },
    "types": [
        "jasmine",
        "jasminewd2",
        "node"
    ],
    "keywords": [
        "Protractor",
        "Typescript"
    ]
}

以前它能够加载应用程序，但现在它正在抛出
