无法解决创建新角度项目的依赖树错误 [英] unable to resolve dependency tree error for creating new angular project

问题描述

所以今天我想使用命令 ng new 创建一个新的 Angular 项目，但我收到了这个错误:

so today I wanted to create a new Angular project using the command ng new <projectname> and I got this error:

npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: project-name@0.0.0
npm ERR! Found: jasmine-core@3.6.0
npm ERR! node_modules/jasmine-core
npm ERR!   dev jasmine-core@"~3.6.0" from the root project
npm ERR!
npm ERR! Could not resolve dependency:

npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

我真的尝试了一切，我更新了npm，再次安装了Angular cli，再次下载并安装了node，npm audit，还有很多其他的事情，但什么也没发生.

I literally tried everything, I updated npm, installed Angular cli again, download and installed node again, npm audit, and a lot of other things but nothing happened.

此外，正如您所看到的，错误告诉我将命令与 --force 一起使用，我尝试过但没有任何反应，并且使用 --legacy-peer-deps，我收到错误为未知选项.

Also as you can see error told me to use the command with --force, I tried but nothing happened, and with --legacy-peer-deps, I get the error as unknown option.

最让我烦恼的是昨晚一切正常，我什么都没做，但今天突然出现了这个错误.

What is bothering me the most is that everything was working completely right last night and I changed nothing at all but suddenly I'm getting this error today.

推荐答案

打开您使用 ng new 创建的文件夹并打开 package.json 文件.在 devDependencies 中更改jasmine-core"的版本；3.6.0 到 3.7.1 和karma-jasmine-html-reporter"从 1.5.0 到 1.6.0 并保存.然后返回终端并转到您的项目并运行 npm install.现在它可以工作了，您可以运行 ng serve.

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. Then go back to Terminal and go to your project and run npm install. Now it works and you can run ng serve.
