安装角度问题！ npm在安装时显示2条警告

Question

命令行文本：

C:\Users\User\Desktop>npm install -g @angular/cli

npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

npm WARN deprecated har-validator@5.1.5: this library is no longer supported

C:\Users\User\AppData\Roaming\npm\ng -> C:\Users\User\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng

@angular/cli@10.1.7 postinstall C:\Users\User\AppData\Roaming\npm\node_modules\@angular\cli

node ./bin/postinstall/script.js

@angular/cli@10.1.7
added 276 packages from 206 contributors in 333.421s

C:\Users\User\Desktop>ng new contacts
'ng' is not recognized as an internal or external command,
operable program or batch file.

已经尝试：

1. 在路径变量中添加了角度。
2. 手动删除AppData / Roaming中的npm目录
3. npm清理缓存--force

Answer 1

首先，您必须安装最新的节点软件包，然后无需在本地安装angular软件包

在每个命令中，在ng之前仅使用npx

npx ng new newApp
npx ng serve
npx ng generate component login
npx ng ...

这将为您工作。
