Question

我构建了一个Web抓取工具，主要使用puppeteer作为后端，使用CLI的inquirer.js。我希望最终用户能够通过按CTRL + C退出程序而不会出现错误。这在运行node built/index.js时非常有效，但是在运行npm start时，按CTRL + C会导致错误：< / p>

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! jmtool@1.0.0 start: `node built/index.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the jmtool@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

关于如何解决此问题的任何想法？（如果相关，我正在使用Windows 10 64位btw。）

我知道答案可能太晚了，但是我刚遇到这个问题。我认为问题出在您使用的节点版本上。就我而言，我正在使用node v12，将版本更改为node v14.7.0，然后删除了node_modules rm -r node_modules，运行了npm install，然后运行了npm start ，并且对我有用。

按下CTRL + C时出现npm错误代码ELIFECYCLE
