按下CTRL+C时，npm错误代码为ELIFECYCLE

Question

我已经构建了一个web抓取工具，主要使用用于后端的puppeteer和用于CLI的inquirer.js。我希望最终用户能够通过按下CTRL+C来无错误地退出进程。这在运行node built/index.js时非常有效，但在运行npm start时，按下CTRL+C会导致错误：

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:
npm ERR!     C:UsersAndiAppDataRoamingnpm-cache_logs2020-07-28T09_46_38_541Z-debug.log

关于如何解决这个问题有什么想法吗？(我使用的是Windows 10 64位btw，以防相关。(

Answer 1

我知道答案可能很晚了，但我刚刚遇到了这个问题。我认为问题出在您使用的节点版本上。在我的案例中，我使用node v12，将版本更改为node v14.7.0，然后删除节点模块rm -r node_modules，运行npm install，然后运行npm start，这对我很有效。
