NPM is telling you 5.0.0 doesnt exist. change your package.json to one of the suggested release candidates like 5.0.0-rc.0. There is a good chance they aren't all exactly that either so read the npm error it is actually helpful in this case.

NPM 告诉你 5.0.0 不存在。将您的 package.json 更改为建议的候选版本之一，例如 5.0.0-rc.0。很有可能它们也并非完全如此，因此请阅读 npm 错误，它在这种情况下实际上很有帮助。

回答by Nimish goel

As Now, angular 5 has been released officially on 1st Novemebr 2017, So for those who want to update your old angular applications to angular 5:

现在，angular 5 已于 2017 年 11 月 1 日正式发布，因此对于那些想要将旧的 angular 应用程序更新为 angular 5 的人：

1) The Angular team has also put a handy toolto make upgrading from any version to angular 5, as simple as possible.

1) Angular 团队还提供了一个方便的工具，使从任何版本升级到 angular 5 尽可能简单。

2) You will have to upgrade all of your angular packages to version 5.0, run the following command:

2) 您必须将所有 angular 包升级到 5.0 版，运行以下命令：

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 zone.js@^0.8.4 @angular/upgrade@^5.0.0 [email protected] rxjs@^5.5.2

3) Angular 5 now also depends on TypeScript 2.4.2 and RxJS 5.5.2, so you'll have to upgrade those package as well.

3) Angular 5 现在也依赖于 TypeScript 2.4.2 和 RxJS 5.5.2，所以你也必须升级这些包。

npm install [email protected] --save-exact

4) If you rely on the date, currency, decimal, or percent pipes, in 5 you will see minor changes to the format. For applications using locales other than en-us you will need to import it and optionally locale_extended_fr from @angular/common/i18n_data/locale_fr and registerLocaleData(local). For more information on pipes breaking changes: https://stackoverflow.com/a/47263949/2810015

4) 如果您依赖日期、货币、小数或百分比管道，则在 5 中您将看到格式的细微变化。对于使用 en-us 以外的语言环境的应用程序，您需要从@angular/common/i18n_data/locale_fr 和 registerLocaleData(local) 导入它和可选的 locale_extended_fr。有关管道中断更改的更多信息：https: //stackoverflow.com/a/47263949/2810015

5) Use of implements instead of extends with any lifecycle events : Ensure you don't use extends OnInit, or use extends with any lifecycle event. Instead use implements .

5) 在任何生命周期事件中使用实现而不是扩展：确保您不使用 extends OnInit，或将扩展与任何生命周期事件一起使用。而是使用 implements 。

6) Switch from HttpModule and the Http service to HttpClientModule and the HttpClient service. HttpClient simplifies the default ergonomics (You don't need to map to json anymore and remove any map(res => res.json())calls, which are no longer needed.) and now supports typed return values and interceptors.

6）从HttpModule和Http服务切换到HttpClientModule和HttpClient服务。HttpClient 简化了默认的人体工程学（您不再需要映射到 json 并删除任何map(res => res.json())不再需要的调用。）并且现在支持类型化返回值和拦截器。

7) The recommended way of importing operators in RxJS 5.5 is from rxjs/operators.

7) RxJS 5.5 中推荐的操作符导入方式是从 rxjs/operators。

import { map, filter, mergeMap, tap } from 'rxjs/operators';

I got the same error even when pasting the command from the Angular upgrade guide.

即使粘贴来自Angular upgrade guide的命令，我也遇到了同样的错误。

In the end, I just changed the versions to the latest and it worked.

最后，我只是将版本更改为最新版本并且它起作用了。

npm install @angular/animations@latest @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest rxjs@latest --save

npm install [email protected] --save-exact

I'm unsure why this error is occurring because even when I type in

我不确定为什么会发生这个错误，因为即使我输入

 npm view @angular/core versions --json

I can see that the version actually exists. My only theory is maybe it's cause I'm on Windows and the Windows version of NPM doesn't like those version numbers...

我可以看到该版本确实存在。我唯一的理论可能是因为我在 Windows 上并且 NPM 的 Windows 版本不喜欢这些版本号......

Before updating, rename your template tags to ng-template.

在更新之前，将您的模板标签重命名为 ng-template。

Update all of your dependencies to the latest Angular and the right version of TypeScript. If you are using Windows, you can use:

将所有依赖项更新到最新的 Angular 和正确版本的 TypeScript。如果您使用的是 Windows，则可以使用：

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' [email protected] rxjs@'^5.5.2'
