Question

我已经有在4版本中运行过的Angular项目。在安装新项目时，不幸的是我已经安装了6版本的cli。这在运行以4版本运行的旧项目中运行ng serve命令时抛出错误“您的全局Angular CLI版本大于您的本地版本”。我再次尝试更新我的anglar本地版本。但是现在我遇到了错误。此版本的CLI仅与Angular 5.0.0或更高版本兼容。我的package.json如下：

 {

  }
}

有人可以解决此错误。从过去的2天开始尝试我，但是我找不到任何合适的解决方案。

Answer 1

我认为这就是您要寻找的。其他答案只是忘记了包含-g参数。

npm install -g @angular/cli@1.4.9

全部都在错误本身中说明。您没有在全球安装它；）希望这能解决您的问题。

更新：要将Angular CLI更新到新版本，必须同时更新全局软件包和项目的本地软件包。

全局软件包：

npm uninstall -g @angular/cli
npm cache verify // If npm version is < 5 then use `npm cache clean`
npm install -g @angular/cli@latest

本地项目包：

// Use rmdir /S/Q node_modules dist in Windows Command Prompt; 
// Use rm -r -fo node_modules, dist in Windows PowerShell

rm -rf node_modules dist 
npm install --save-dev @angular/cli@latest
npm install

有关更多info的信息，请查看GitHub上的自述文件。

将CLI版本1.4.9与角度4一起使用。

npm install @angular/cli@1.4.9

"devDependencies": {
    "@angular-devkit/build-angular": "~0.7.0",
    "@angular/cli": "1.4.9",
    ....
    ....
  }

Answer 3

您可以通过运行以下方法解决问题：

npm install --save-dev @angular/cli@latest
