npm install显示无法解析ERESOLVE消息

Question

当我npm install某事时，我看到这个错误消息:

code ERESOLVE
npm ERR! ERESOLVE could not resolve
npm ERR! 
npm ERR! While resolving: @angular-devkit/build-angular@12.2.17
npm ERR! Found: @angular/compiler-cli@14.0.3

虽然我知道我可以用--force或--legacy-peer-deps安装它，但我想解决根本问题，我应该具体安装哪个包?在错误消息中，我看到问题是来自@angular/compiler-cli@"^12.0.0,@angular-devkit/build-angular@12.2.17，但哪一个是它，在一个更广泛的问题中，我如何解释这个错误消息?

Answer 1

在我看来，没有angular 12.2.17版本。我找到的最后一个版本是12.2.16(出自v12)分支。如果我试图找到版本12.2.17的@angular/core，我找不到它(https://www.npmjs.com/package/@angular/core/v/12.2.17 ->404)CLI的版本似乎是12.2.17

你可以尝试用ng update更新你的依赖项。Angular cli会尝试将你的依赖项更新到最新版本，并配置你的package.json编辑:您可以使用ng update @angular/cli@^12 @angular/core@^12只升级到版本12的最新更新(在这里找到->https://angular.io/cli/update)

如果你不想要最新版本(目前是v14)，因为你不能迁移，尝试将所有angular包更改为v.12.2.16。它们应该都匹配最好使用cli和ng update @angular/cli@^12 @angular/core@^12来匹配你的包
