angular-cli 全局全新安装后找不到@angular-devkit/core 模块 [英] @angular-devkit/core module not found after angular-cli global fresh install

问题描述

使用 npm，我已经全局安装了 angular-cli，命令 npm install -g @angular/cli.

Using npm, I have installed angular-cli globally, with the command npm install -g @angular/cli.

安装成功后，包括ng -v在内的每个命令都返回相同的错误:

After installing it succesfully, every command including just ng -v, returns the same error:

Error: Cannot find module '@angular-devkit/core'

推荐答案

@angular-devkit is required by @angular/cli 因为依赖可能是 npm 出了问题安装.

@angular-devkit is required by @angular/cli as dependency maybe something went wrong with npm install.

所以卸载 @angular/cli :

npm uninstall -g @angular/cli

然后使用以下命令清除 npm 缓存:

Then clear the npm cache with:

npm cache clean --force

然后重试安装.
