Question

所以我一直在开发离子应用程序，当我构建它时，我得到了 this error。这是图像的完整代码。

        Re-running this command with the --verbose flag may provide more information.

似乎我的node_modules中缺少调度程序/操作模块。通过执行以下操作，我搜索了一个答案并得到了一个解决方案，这是一个临时解决方案：

npm install rxjs@^6.0.0 --save

然后：

npm install --save rxjs-compat

通过执行这些命令，我可以构建我的应用程序。但是经过一些构建后，错误又回来了，我不得不重新执行这两个命令。

here is a log whit some warnings that i get after the comands

我认为问题出在我一天前的最新更新中。我试图更新angular，angularCLI和rxjs，但我认为我做错了。

这是我的应用程序的package.json及其相关版本

我想知道如何解决模块问题。我认为我必须正确更新我的angular和rxjs或安装一些angular和rxjs依赖项，但是我根本不知道从哪里开始，也不想弄乱我的应用程序。

谢谢你，如果我做错了事，这是我的第一个问题。

Answer 1

经过了一整天的解决方案后，我重新将角度和cli重新安装到最新版本

npm install -g @angular/cli@latest

然后执行了该命令

npm i rxjs@6 rxjs-compat@6 promise-polyfill --save

这使问题消失了。
