如何在特定目錄中安裝NPM？

Question

我知道有一個duplicate here。但無論有多少變化試試，我不斷收到一個錯誤信息：
Error: ENOENT, stat 'd:\wamp\www\test\js\

我已經試過：

npm install --prefix video.js ./wamp/www/test/js 
npm install --prefix video.js ./wamp/www/test/js -g 
npm install video.js ./wamp/www/test/js/video.js 
npm install --localapp video.js ./wamp/www/test/js 
npm install video.js D:\wamp\www\test\js -g 
npm install --prefix video.js D:\wamp\www\test\js 

什麼是用於安裝的Video.js正確的語法？

運行npm install --prefix video.js ./wamp/www/test/js創建下列錯誤日誌：

Answer 1

我覺得你混合相對和絕對路徑。你的日誌文件顯示如下：

... 
error Error: ENOENT, stat 'D:\wamp\www\test\js\wamp\test\js' 
... 

這會導致你想要使用兩次的路徑。

要麼你需要給出一個絕對路徑：

npm install --prefix video.js d:/wamp/www/test/js 

或保持相對：

npm install --prefix video.js ./
