Question

我真的很茫然。我为我的应用程序安装了ngx-translate，但它需要我更新我的@ angular / core和rxjs。我决定使用https://angular-update-guide.firebaseapp.com/完全更新Angular。它告诉我：

npm install @angular/animations@'^5.0.0' @angular/common@'^5.0.0'
@angular/compiler@'^5.0.0' @angular/compiler-cli@'^5.0.0' @angular/core@'^5.0.0' 
@angular/forms@'^5.0.0' @angular/http@'^5.0.0' @angular/platform-browser@'^5.0.0' 
@angular/platform-browser-dynamic@'^5.0.0' 
@angular/platform-server@'^5.0.0' @angular/router@'^5.0.0'typescript@2.4.2 rxjs@'^5.5.2'

当我将其粘贴到我的控制台并点击回车时，我收到以下错误：

我还试图只更新@ angular / core和rxjs，但是当我举例npm install @angular/core@5.0.0时，我收到了以下消息：

+-- @angular/cli@1.2.0
| `-- rxjs@5.5.6
|   `-- symbol-observable@1.0.1
+-- UNMET PEER DEPENDENCY @angular/core@5.0.0
`-- UNMET PEER DEPENDENCY  (rxjs) invalid error: ENOENT: no such file or directory, open 'c:\pdws-view-v2\node_modules\rxjs\package.json

还有一堆像这样的警告：

npm WARN @angular/animations@4.4.4 requires a peer of @angular/core@4.4.4 but none was installed.

此外，在尝试安装这些后，我的应用程序将不再编译，给我这个错误：

Failed to compile.

./~/@angular/core/@angular/core.es5.js
Module build failed: Error: ENOENT: no such file or directory, open 'c:\pdws-view-v2\node_modules\@angular\core\@angular\core.es5.js'
    at Error (native)
 @ ./src/main.ts 1:0-47
 @ multi webpack-dev-server/client?http://localhost:4200 ./src/main.ts

此时我该怎么办？感谢。

清除缓存并重新安装

npm cache clean
npm install @angular/animations@'^5.0.0' @angular/common@'^5.0.0'
@angular/compiler@'^5.0.0' @angular/compiler-cli@'^5.0.0' @angular/core@'^5.0.0' 
@angular/forms@'^5.0.0' @angular/http@'^5.0.0' @angular/platform-browser@'^5.0.0' 
@angular/platform-browser-dynamic@'^5.0.0' 
@angular/platform-server@'^5.0.0' @angular/router@'^5.0.0'typescript@2.4.2 rxjs@'^5.5.2'

使用npm更新Angular时出错
