NPM安裝引發錯誤錯誤：無效的協議

Question

您好我是新來的節點JS，我試圖按照書中的樣品，並嘗試做NPM安裝我收到以下錯誤時：

任何幫助將是高度讚賞

我的節點JS的配置是

C:\Developer\NODE_JS>npm config list 
; cli configs 
registry = "http://registry.npmjs.org/" 

; userconfig C:\Users\<uname>\.npmrc 
https-proxy = "proxy.<comp>.com:8080" 
proxy = "proxy.<comp>.com:8080" 
registry = "http://registry.npmjs.org/" 

; builtin config undefined 
prefix = "C:\\Users\\puppalap\\AppData\\Roaming\\npm" 

; node bin location = C:\Program Files\nodejs\\node.exe 
; cwd = C:\Developer\NODE_JS 
; HOME = C:\Users\<uname> 
; 'npm config ls -l' to show all defaults. 

Answer 1

後，我設置以下兩個屬性的問題得到了解決：

npm config set proxy http://usr:pwd@host:port 
npm config set https-proxy http://usr:pwd@host:port 

Answer 2

問題是由於設置了windows http_proxy環境變量;而我不使用代理。

如果設置了http_proxy，將顯示命令提示符中的以下命令;

set http 

如果設置刪除變量與下面的命令和問題解決。

set http_proxy= 

Above command will remove the http_proxy from the current command line. However, if you need to permanently remove it, just remove it from System Properties>Advanced Tab>Environment Variables dialog box.

想和大家分享的方法，我也跟着的方式，尋求解決辦法，

My error: was ERR! Error: Invalid protocol : myusername:

[以前代理的用戶名]

在我的.npmrc文件 包含註冊表=「http://registry.npmjs.org/」 和其他變量[前綴，密碼，主頁]

因爲我不是代理的背後，除去代理變量 還是得到了同樣的錯誤

when looked into request.js[/usr/lib/node_modules/npm/node_modules/request/request.js] file it is using the old proxy values

因此，我加入的init（）request.js的

self.proxy="http://registry.npmjs.org/" //at the start of method 

然後它開始行加工！！！

PS：一旦安裝命令後，刪除此行，它繼續工作。 嘗試這個，如果沒有其他選項正在工作
