用简单的新角度cli项目投掷错误 [英] ng serve throwing errors with simple ng new angular cli project

问题描述

我是 angular-cli 的新用户，并使用 ng new angular2 命令创建了一个角度为2的项目。现在，当我尝试使用 ng serve 运行它时，它只会因某些错误而崩溃。

I am new to a angular-cli and have created an angular 2 project with ng new angular2 command. Now when I try to run it with ng serve, it just crashes with some errors.

日志：

ERROR in [default] C:\Users\user\desktop\angularcli\node_modules\@types\jasmine\index.d.ts:39:37
A parameter initializer is only allowed in a function or constructor implementation.

ERROR in [default] C:\Users\user\desktop\angularcli\node_modules\@types\jasmine\index.d.ts:39:45
Cannot find name 'keyof'.

ERROR in [default] C:\Users\user\desktop\angularcli\node_modules\@types\jasmine\index.d.ts:39:51

         Asset     Size  Chunks       Chunk Names
    index.html  2.81 kB       0
webpack: Failed to compile.

我不知道为什么我得到这个跟踪，因为我没有对文件做任何更改。
有谁知道为什么会出现这个错误或者之前有人遇到过它。

I don't know why I get this trace as I haven't made any changes in the files. Does anyone know why this error occurs or someone might have encountered it before.

分享我运行的配置 ng --version -

Sharing the config that I get on running ng --version-

angular-cli: 1.0.0-beta.18
node: 6.9.5
os: win32 x64

感谢您的帮助。

推荐答案

我有同样的问题，你仍然使用角度cli的beta版本 - 他们现在有一个RC版本。升级将解决您的问题。另外值得注意的是，该项目已在NPM中移动，现在 @ angular / cli 而不是 angular-cli 。

I had this same problem, you are still using the beta version of angular cli - they have now have an RC version. Upgrading will fix your issue. Also worth noting that the project has moved in NPM it is now @angular/cli instead of angular-cli.

本页将向您展示如何升级 - 它提供了有关如何全局升级以及如何升级单个项目的说明（您需要同时进行升级）。

This page will show you how to upgrade - it gives instructions on how to upgrade globally and also how to upgrade individual projects (you will need to do both).

注意：不是必需但如果您没有运行节点6.9 +

Note: Not essential but it will also give you warnings if you aren't running Node 6.9 +
