问题描述
我对 angular 很陌生,我正在从几个月前开发的一个项目中学习.
I'm very new to angular and i am learning from a project that has been developed some months back.
节点 v 是 12.13.1npm v 是 6.12.1
node v is 12.13.1npm v is 6.12.1
- 我在 Windows 操作系统中工作.
- 当我尝试 ng --version 或 ng -v 或 ng v 时,它显示术语 ng 未被识别为 angular 中的 cmdlet 名称".
- 但是使用 npm list -global --depth 0 告诉我@angular/cli@8.3.21.
- 使用 npm start 运行应用程序,因为 ng serve 不起作用.
我尝试按照以下链接中给出的步骤更新 angularCli,但仍然相同.https://www.npmjs.com/package/@angular/cli
I tried Updating angularCli by following the steps given in the below link but still the same.https://www.npmjs.com/package/@angular/cli
请帮我解决这个问题.提前致谢.
please help me to solve this issue.Thanks in advance.
推荐答案
Open Node JS 命令提示
Open Node JS command Prompt
首先全局卸载angular cli
First uninstall angular cli globally
npm uninstall -g @angular/cli
npm 缓存清理 --force
安装最新的 angular cli
Install latest angular cli
npm install -g @angular/cli
您将只能在 Node JS 命令提示符下访问 ng 变量.如果您使用任何其他终端,例如 windows CMD 或 bash ng 命令将不起作用.要使其工作,您需要设置 npm 环境变量.要设置环境变量,您需要管理员权限.
You will be able to access ng variable in Node JS command prompt only. If you are using any other terminal such as windows CMD or bash ng command will not work. To make it work you need to set npm environment variables. To set environment variables you need admin access.
