推荐答案

可以通过以下更改来解决:

只需转到Ionic中的以下文件

plugins/cordova-universal-links-plugin/hooks/lib/android/manifestWriter.js

plugins/cordova-universal-links-plugin/hooks/lib/android/manifestWriter.js

我通过如下更改pathToManifest来解决此问题:

var pathToManifest = path.join(cordovaContext.opts.projectRoot, 'platforms', 'android', 'cordovaLib', 'AndroidManifest.xml');

到

var pathToManifest = path.join(cordovaContext.opts.projectRoot，平台"，'安卓'，'应用程序'，'src'，'主要的'，'AndroidManifest.xml');

var pathToManifest = path.join( cordovaContext.opts.projectRoot, 'platforms', 'android', 'app', 'src', 'main', 'AndroidManifest.xml');
