npm 在 linux 上安裝失敗

Question

剛開始學習vue的課程，所以對node完全不熟悉。 我所知道的是，當我第一次克隆課程的 repo 時，我按照說明進行操作，一切順利，運行沒有問題。 由於錯誤地運行 npm 構建，這弄亂了我克隆的文件夾結構，所以我刪除了整個文件夾並重新克隆它，現在 npm 安裝失敗，我無法弄清楚發生了什么。

這是我運行 npm 安裝時返回的內容，我可以確認我在正確的文件夾中：

我可以看到 python2.7 命令試圖運行，但我不知道為什么，我的 linux 盒子上的 python 來自 Anaconda3，它經常更新，過去 10 年來一直是我的主要 python3。 上次沒有失敗，所以我懷疑問題實際上是我安裝的 node.js，因為這是唯一真正的未知數，因為我對節點一無所知，只需按照 vue.js 站點上的安裝說明安裝節點，以下是我安裝的版本：

node --version
v14.15.4

npm --version
6.14.10

vue --version
@vue/cli 4.5.11

最后是我為課程克隆的 git 存儲庫：

任何有關發生的事情的見解將不勝感激。

我通過清除緩存找到了解決此問題的方法，如下所示：

npm cache clean --force

manually deleting node modules package-lock.json

npm 安裝然后按預期工作。
