2 錯誤詳解

該錯誤發生在修改npm的全局安裝路徑之后，再執行npm install 包 -g或是npm install 包時發生，但是在管理員身份下運行cmd，均能執行成功。

2.1 修改npm全局安裝：

1.命令行：

npm config set prefix "D:\NodeJS\node_global"
npm config set cache "D:\NodeJS\node_cache"

在C盤User/用戶名/下有一個.npmrc的文件

2.將上述node_global文件夾的路徑加入環境變量

2.2 導致該安裝問題的原因

沒有管理員權限，無法在node_global和node_cache兩個文件夾下進行一些必要的操作

2.3 修復方法

• 刪除用戶下的.npmrc文件，即不改變全局安裝的路徑（不夠好，本質問題仍沒有解決，全局還是會安裝在C盤）

• 每次都用管理員身份運行命令行（不夠方便，vscode 下的命令行默認也不是管理員身份運行的）

• 直接修改node_global和node_cache文件夾的權限：

右鍵文件夾，打開屬性，切換到安全選項卡

選擇編輯，將沒有打鉤的位置全部打上鉤（即將其它用戶的權限設置為與管理員相同），應用即可。

3 運行測試

安裝webpack測試，成功！

npm i webpack webpack-cli -g
npm i webpack webpack-cli --save-dev
