安装 Angular CLI 时收到错误警告

问题描述

我是这个平台的新手.

我安装了 Node.js 但是当我尝试运行命令 npm install -g @angular/cli我收到此错误:

I installed Node.js but when I try to run command npm install -g @angular/cliI received this error:

**npm WARN deprecated [email protected]: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)
npm WARN deprecated [email protected]: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN rollback Rolling back @schematics/[email protected] failed (this is probably harmless): EPERM: operation not permitted, lstat 'C:\Users\Vivek\AppData\Roaming\npm\node_modules\@angular\cli\node_modules\@sche**

此外，当我尝试运行版本的命令时

Also when I try to run command for version

它显示了我

**C:\Users\Vivek>ng v
internal/modules/cjs/loader.js:985
  throw err;
  ^
Error: Cannot find module 'C:\Users\Vivek\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng'**

推荐答案

试试这个...

要将所有软件包更新到新的主要版本，请全局安装 npm-check-updates 软件包:

To update to a new major version all the packages, install the npm-check-updates package globally:

npm install -g npm-check-updates

然后运行 ​​ncu:

then run ncu:

ncu -u  --packageFile package.json

这会将 package.json 文件中的所有版本提示升级到依赖项和 devDependencies，因此 npm 可以安装新的主要版本.您现在已准备好运行更新:

this will upgrade all the version hints in the package.json file, to dependencies and devDependencies, so npm can install the new major version.You are now ready to run the update:

npm update

忽略任何审核建议并再次运行安装...

ignore any audit suggestions and run install again...

npm install

这应该是弃用警告.
