如何修复 ERESOLVE 无法解析 npm install 的依赖关系树

Question

我目前对角度和自学还比较陌生。以前一切都工作正常，直到我决定将很多新东西导入到我的项目中。简而言之，我发现我可以删除 node_modules 并运行 npm install。删除它后，当我运行 npm install 时出现以下错误。

npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: appla-katta@0.0.0
npm ERR! Found: @angular/common@12.2.16

我不确定该错误意味着什么，但我认为我有不同的版本，因为我猜存在依赖错误。我尝试跑步npm install @angular/cdk@latest，ng update @angular/common但没有结果。我什至找到了更多解决方案，例如删除节点模块，但package_lock.jsonnpm install 不起作用。

我尝试强制 npm install 但由于其他原因我的项目没有运行，所以我希望解决这里的错误本身

谢谢

以下是我的 package.json 内容

另外，我还有 package-lock.json，现在已将其删除。

删除node_modules和package-lock.json.

然后试试这个：

npm install --legacy-peer-deps
