Question

我正在Windows 7系统上安装Angular新项目，我在安装时遇到问题有什么办法解决这个问题吗？

我创建了一个新的角度项目它给出了错误我也尝试在旧项目中安装npm，但无法再次使用，我也尝试再次安装打字稿，我也尝试删除package-lock.json并再次安装npm，然后我尝试了ng v

当ng v得到这个

Angular CLI: 8.0.3
Node: 10.16.0
OS: win32 ia32
Angular: <error>
... animations, cli, common, compiler, compiler-cli, core, forms
... language-service, platform-browser, platform-browser-dynamic
... router

Package                         Version
---------------------------------------------------------
@angular-devkit/architect       0.800.3 (cli-only)
@angular-devkit/build-angular   <error>
@angular-devkit/core            8.0.3 (cli-only)
@angular-devkit/schematics      8.0.3 (cli-only)
@schematics/angular             8.0.3 (cli-only)
@schematics/update              0.800.3 (cli-only)
rxjs                            6.4.0 (cli-only)
typescript                      <error>

我希望运行该程序创建新的角度项目时会收到此错误消息

有什么办法解决这个问题？

Answer 1

这似乎是您的 node / npm 的问题，而不是 Angular CLI 的问题。

第1步：以管理员身份卸载angular / cli和nodejs。

第2步：从%appdata%（npm，npm-cache）中删除文件夹，或使用以下命令npm cache clean

第3步：从程序和文件中删除“ nodejs”文件夹

第4步：重新启动

第5步重新启用最新版本的节点

Setp 6：安装angular / cli
