npm install時出錯

Question

我是一名初學者，我正在嘗試學習Angular，所以我正在嘗試使用angular-seed安裝一個新項目。但是，當我做npm安裝時，我得到一個錯誤，我不知道從哪裏來。我安裝了節點。版本是5.5.0。廣告這是我在控制檯中得到的錯誤。

Answer 1

「請嘗試以root/Administrator身份再次運行此命令。」

嘗試sudo npm install。

Answer 2

也許來不及回答，但這是一個權限問題。您必須修復此目錄的權限，並在沒有sudo的情況下運行npm install。

cd your_working_directory 
sudo chown -R $(whoami):$(whoami) . 
sudo chmod -R 755 . 
npm install 

Answer 3

ISSUE：你（用戶）沒有一套正確的目錄權限。

即時解決方法是使用sudo運行npm install，但這可能會導致相同的錯誤或安裝不當。

解決方案/建議：改變故宮的默認目錄（來自官方docs）

備份您的計算機前進了。

（可選）如果你有一個錯誤的安裝，先卸載它：

npm uninstall <package-name> # use sudo if you used it while installation 
npm cache verify # or, npm cache clean for npm version below 5.x.x 

1. 建立一個目錄全球安裝：

   mkdir ~/.npm-global

2. 配置NPM使用新的目錄路徑：

   npm config set prefix '~/.npm-global'

3. 打開或創建一個~/.profile或~/.bash_profile文件，加入這一行：

   export PATH=~/.npm-global/bin:$PATH

4. 回到命令行上，更新系統變量，或重新啓動終端：

   source ~/.profile

5. （可選）測試：在不使用sudo的情況下全局下載軟件包。

   npm install -g jshint
