从 ionic 4 更新到 5 ionic cordova android livereload 错误-复制插件

Question

我正在尝试将我的 angular ionic 4 应用程序更新为 ionic 5。我使用了以下链接：

https://ionicframework.com/docs/reference/migration

npm install @ionic/angular@latest @ionic/angular-toolkit@latest --save

尝试进行 livereload 时出现以下错误：

ionic cordova run android -l
[INFO] Hardware device(s) found for android. Using --device.
> ng run app:ionic-cordova-serve --host=localhost --port=8100 --platform=android
[ng] An unhandled exception occurred: Invalid options object. Copy Plugin has been initialized using an options object that does not match the API schema.
[ng]  - options[0] misses the property 'patterns'. Should be:
[ng]    [non-empty string | object { from, to?, context?, globOptions?, toType?, force?, flatten?, transform?, cacheTransform?, transformPath?, noErrorOnMissing? }, ...] (should not have fewer than 1 item)
[ng] See "/private/var/folders/1k/dwr2csfs5lnfrs7xq7520v_w0000gq/T/ng-OE3Uo3/angular-errors.log" for further details.

[ERROR] ng has unexpectedly closed (exit code 127).
        
        The Ionic CLI will exit. Please check any output above for error details.

然后我跑了 ionic doctor 看看是否有任何问题。 没有。

有趣的是，我可以成功构建一个.apk 并使用ionic cordova build android --prod --release运行它

即使在成功构建之后 livereload 命令仍然失败并出现相同的错误。

ionic cordova run android -l

该错误确实指向日志文件以获取更多信息。 这是我发现的：

error] ValidationError: Invalid options object. Copy Plugin has been initialized using an options object that does not match the API schema.
 - options[0] misses the property 'patterns'. Should be:

它指向许多 node_modules：

node_modules/copy-webpack-plugin - version - 6.0.3
node_modules/@ionic/angular-toolkit
node_modules/@angular-devkit

我的离子信息是：

   Ionic CLI                     : 6.11.0 (/Users/b/.nvm/versions/node/v12.18.3/lib/node_modules/@ionic/cli)

更新：然后我创建了一个全新的基于 angular 的 Ionic 5 项目。

然后我使用以下命令添加了 cordova android 平台：

ionic cordova platform add android

我运行以下命令来进行 livereload：

ionic cordova run android -l

仍然看到错误。

我创建了一个仓库 https://github.com/ASHBAW/test_livereload

还有人看到这个吗？

回购在您的系统上工作吗？

任何帮助将不胜感激。

谢谢

对我来说，解决方案（解决方法）是将@ionic/angular-toolkit回滚到以前的版本，似乎与v2.3.1 。

npm i @ionic/angular-toolkit@2.3.0 -E -D

更新

新版本的@ionic/angular-toolkit似乎解决了这个问题，尝试安装最新版本：

npm i @ionic/angular-toolkit@latest -D
