在 Visual Studio 代码中调试量角器测试时出现 Cucumber 错误，但在运行模式下一切正常

Question

我在“视觉工作室代码”中对量角器黄瓜进行了基本设置，当我从终端运行它时，一切正常。但是，当我通过 Visual Studio 代码调试它时，它给了我版本错误。我还没有在全球范围内安装 Cucumber。我通过本地目录中的 npm install 安装了它，但错误消息仍然说我保留了两个不同的版本。怎么可能呢？

此错误消息也应该在运行模式下出现，为什么它只在调试模式下出现。请参阅下面的错误。

You appear to be executing an install of cucumber (most likely a global 
install)
that is different from your local install (the one required in your support 
files).
For cucumber to work, you need to execute the same install that is required 
in your support files.
Please execute the locally installed version to run your tests.

以下是运行“npm install”后安装的 package.json 的依赖项

{
"devDependencies": {
"babel-cli": "^6.26.0",
"babel-preset-es2015": "^6.24.1",
"babel-register": "^6.26.0",
"chai": "^4.1.2",
"chai-as-promised": "^7.1.1",
"cucumber": "^3.2.1",
"cucumber-html-report": "^0.6.2",
"cucumber-html-reporter": "^3.0.4",
"cucumberjs-allure-reporter": "^1.0.3",
"mkdirp": "^0.5.1",
"protractor": "^5.2.0",
"protractor-cucumber-framework": "^4.1.1"
},

            "program": "${workspaceRoot}/node_modules/protractor/bin/protractor",
        "stopOnEntry": false,
        "args": [
            "${workspaceRoot}/config/config.js"
        ],
    }
]
}

Answer 1

在您的调试配置中添加"cwd": "${workspaceFolder}",后面"name": "Launch Program",，然后重试。
