部署ionic应用程序时如何解决“运行子进程ng时发生错误”？

Question

我最近制作了一个离子应用程序，当我尝试使用它进行部署时

ionic cordova build android

我收到以下错误：

An unhandled exception occurred: [BABEL] C:\Users\dipes\OneDrive\Documents\GitHub\demoapp\www\focus-visible-15ada7f7-js-es2015.js: Could not find plugin "proposal-numeric-separator". Ensure there is an entry in ./available-plugins.js for it. (While processing: "C:\\Users\\dipes\\OneDrive\\Documents\\GitHub\\demoapp\\node_modules\\@babel\\preset-env\\lib\\index.js")
See "C:\Users\dipes\AppData\Local\Temp\ng-8Jt401\angular-errors.log" for further details.
[ERROR] An error occurred while running subprocess ng.

在日志文件中，我得到
