ERESOLVE无法解析依赖树。带有vue js的.net核心3.1

Question

我正在尝试构建我的应用程序，但是出现了以下错误

npm ERR! code ERESOLVE
  npm ERR! ERESOLVE unable to resolve dependency tree
  npm ERR!
  npm ERR! While resolving: clientapp@0.1.0
  npm ERR! Found: vue@2.6.14
  npm ERR! node_modules/vue
  npm ERR!   vue@"^2.6.12" from the root project
  npm ERR!
  npm ERR! Could not resolve dependency:
  npm ERR! peer vue@">=3.0.0" from vue-chartkick@1.1.0
  npm ERR! node_modules/vue-chartkick
  npm ERR!   vue-chartkick@"^1.0.0" from the root project
  npm ERR!
  npm ERR! Fix the upstream dependency conflict, or retry
  npm ERR! this command with --force, or --legacy-peer-deps
  npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

不管怎么说，我都错过了

错误MSB3073:命令“”与代码1一起退出。

Answer 1

起作用的是删除%appdata%\漫游\npm-缓存文件夹本地node_modules文件夹

Answer 2

从错误来看，您似乎安装了Vue 2，但是包vue-chartckick正在寻找Vue 3。

此外，一揽子自述文件指出：

最新版本适用于Vue 3。对于Vue 2，使用版本0.6.1和这个自述https://github.com/ankane/vue-chartkick/blob/v0.6.1/README.md。

因此，解决方案要么使用该包的推荐版本，要么将Vue升级到版本3。
