如何在運行 Node JS 應用程序時解決 NPM 代理問題

Question

我已經安裝了 Noed JS 和 NPM。我已經從 git 克隆了 repo 並嘗試在本地運行該應用程序。 但是我在運行應用程序時面臨以下代理問題。

 npm install nodemon npm ERR: code ENOTFOUND npm ERR. errno ENOTFOUND npm ERR..network request to https,//registry:npmjs.com/nodemon failed. reason, getaddrinfo ENOTFOUND 28 npm ERR..network This is a problem related to.network connectivity: npm ERR!.network In most cases you are behind a proxy or have bad.network settings. npm ERR!.network npm ERR!.network If you are behind a proxy, please make sure that the npm ERR!.network 'proxy' config is set properly. See: 'npm help config'`

我已經檢查過代理，它被設置為 below.network。

 Pinging proxy.internal.domainname.com with 32 bytes of data: Reply from <ip address="">: bytes=32 time=2ms TTL=247 Reply from <ip address="">: bytes=32 time=2ms TTL=247 Reply from <ip address="">: bytes=32 time=2ms TTL=247 Reply from <ip address="">: bytes=32 time=2ms TTL=247 Ping statistics for <ip address="">: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 2ms, Maximum = 2ms, Average = 2ms

我嘗試使用以下命令將代理設置為https://registry.npmjs.com/nodemon 。

npm config set registry "http://registry.npmjs.org/ 

當我在此之后運行 npm install 時，我再次遇到同樣的錯誤。

 npm --proxy http://registry.npmjs.org/ install npm npm ERR: code ENOTFOUND npm ERR. errno ENOTFOUND npm ERR..network request to http,//registry:npmjs.org/npm failed. reason, getaddrinfo ENOTFOUND 28 npm ERR..network This is a problem related to.network connectivity: npm ERR!.network In most cases you are behind a proxy or have bad.network settings. npm ERR!.network npm ERR!.network If you are behind a proxy, please make sure that the npm ERR!.network 'proxy' config is set properly. See: 'npm help config'`

我已經嘗試了谷歌的許多其他解決方法，但仍然面臨同樣的代理問題。 我只是想在本地運行這個應用程序，這樣我就可以在部署之前在本地測試我的代碼。 我在這里錯過了什么嗎？

編輯：

運行npm config ls命令返回以下結果：

 ; cli configs metrics-registry = "http://registry.npmjs.org/async-each" scope = "" user-agent = "npm/6.13.4 node/v12.14.0 win32 x64"; userconfig C:\Users\username\.npmrc https-proxy = "http://registry.npmjs.org/" https://registry.npmjs.com/nodemon = "" key = "" registry = "http://registry.npmjs.org/" strict-ssl = false; builtin config undefined prefix = "C:\\Users\\username\\AppData\\Roaming\\npm"; node bin location = C:\Program Files\nodejs\node.exe; cwd = H:\IRB PMX Services\core\src; HOME = C:\Users\username; "npm config ls -l" to show all defaults.

編輯 2：

我現在運行以下命令來刪除錯誤的配置鍵，即https://registry.npmjs.com/nodemon = ""部分：

npm config delete https://registry.npmjs.com/nodemon

並再次運行npm install命令。 但再次出現如下代理錯誤：

 npm ERR..network request to registry.npmjs,org/async-each/@types%2fnode failed: reason. read ECONNRESET npm ERR..network This is a problem related to.network connectivity, npm ERR..network In most cases you are behind a proxy or have bad.network settings. npm ERR..network npm ERR!.network If you are behind a proxy, please make sure that the ...

Answer 1

這為我修好了：

npm config delete proxy

npm config delete http-proxy

npm config delete https-proxy

快樂編碼！

Answer 2

我已經通過以下步驟解決了這個問題：

1. 確保您有互聯網連接：ping 8.8.8.8
2. 確保您的 DNS 解析器正常工作：ping www.google.com
3. 確保您可以訪問 registry.npmjs.org：ping registry.npmjs.org
4. 確保您可以通過 https 連接。

在 npm 命令提示符或 Visual Studio Code 終端中運行以下命令。

npm config rm proxy

npm config rm https-proxy

在瀏覽器中嘗試： https : //registry.npmjs.org/

確保您嘗試連接到：

registry.npmjs.org

而不是：

“registry.npmjs.org registry.npmjs.org:443”

使用以下命令設置注冊表。

npm config set registry https://registry.npmjs.org/

如果您使用代理訪問 Web，那么您還必須配置 npm 才能使用它。 用：

npm config set proxy http://username:password@proxyname:8080

npm config set https-proxy http://username:password@proxyname:8080

設置以上兩個值時要記住的要點：

1. 您需要與您公司的網絡團隊核對代理名稱。 在以上 2 個值中輸入該代理 URL。
2. 如果您的密碼包含任何特殊字符，則將其替換為編碼字符。 在此命令中，您不能提供帶有特殊字符的密碼。 僅替換特殊字符而不是 .（點）。

   例如：密碼是：Welcome@12# 那么它就會像 Welcome%4012%23。

然后嘗試運行您的 npm install 命令，它應該可以工作。
