我正在嘗試建立我的應用程序，但出現以下錯誤

npm ERR! code ERESOLVE
  npm ERR! ERESOLVE unable to resolve dependency tree
  npm ERR!
  npm ERR! While resolving: [email protected]

我缺少什麼想法

Answer 1

從錯誤來看，您似乎安裝了 Vue 2，但軟體包 vue-chartckick 正在尋找 Vue 3。

此外，套件自述文件指出：

因此，解決方案是使用建議版本的軟體包或將 Vue 升級到版本 3。

Answer 2

有效的是刪除 %appdata%\Roaming\npm-cache 資料夾本機的node_modules資料夾
