我试图创建新的 Angular 项目，但遇到了这个错误。我在这里粘贴了我的错误和 angular 的版本及其使用的依赖项（ng 版本）。我使用安装程序安装 Node.js，使用 cmd 命令安装 angular cli。但是我无法创建新项目（ng new project-name）请帮我解决这个问题。提前致谢

Answer 1

这是一些过时包在 angular-cli 中的错误，已在 github 的存储库中解决，但尚未发布到 npmjs，您可以解决有两种方式：

安装包时使用“--legacy-peer-deps --force”
像 https://github.com/angular/angular-cli/commit/b34ed5c4007f9ef08b370219081b4d23f9f24fb8

这是 angular-cli github repo https://github.com/angular/angular-cli/issues/20719

上此错误的未决问题

Answer 2

您还可以使用 npm install -g npm@6 将 npm 从 7 降级到 6 来解决这个问题

如果您在安装过程中遇到其他问题，请删除 npm 和 npm-cache in: \AppData\Roaming 然后重试

Answer 3

检查，是同一个问题。

Open the folder you create with ng new and open the package.json file. In devDependencies change the version of "jasmine-core" 3.6.0 to 3.7.1 and "karma-jasmine-html-reporter" from 1.5.0 to 1.6.0 and save it. Than go back to Terminal and go to your project and run npm install. Now it works und you can run ng serve.

Answer 4

更新或新安装@angular/cli

npm install -g @angular/cli

Answer 5

我遇到了类似的错误，所以我选择了一个使用 n 库的较新节点版本，如下所示：https://nkaushik.com/nodejs/nodejs-version-manager-n/

然后我更新了我的 angular 版本：

install -g @angular/cli

哦，别忘了关闭你的 VPN

Answer 6

解决方法

启动新的 Angular 项目有一个解决方法：

ng new project --skip-install

cd project

npm install（或者如果失败 npm install --force）

我在 angular-cli github repo 上的这个错误的未解决问题的评论中发现了这一点，Ammar M Mashfj 在他们的回答中链接到： https://github.com/angular/angular-cli/issues/20719#issuecomment-835810313
