我想安裝 ReactJs。我已經安裝了 Nodejs，然后嘗試創建 ReactJs 項目文件夾，我使用
npx create-react-app my-app根據 ReactJs 文檔但這是我得到的錯誤：-

Answer 1

Go轉

C:\Users\username

然后搜索

.npmrc

使用記事本打開.npmrc文件並刪除所有內容和過去

http_proxy=http://domain:8080

這對我有用。

Answer 2

基於錯誤消息中的這一行：

npm ERR! network request to https://registry.npmjs.org/webpack-dev-server/-/webpack-dev-server-3.11.0.tgz failed, reason: getaddrinfo ENOTFOUND proxy.company.com

...您已將proxy.company.com設置為某處的代理。 找到它並將其修復為您實際需要的設置，或者如果您不需要代理（這是標准/典型情況）則將其刪除。 在后一種情況下，使用npm config delete proxy ，然后嘗試安裝。

也許您正在按照https://jjasonclark.com/how-to-setup-node-behind-web-proxy/或在其示例中使用proxy.company.com的相關教程中的說明進行操作。
