create-react-app 命令失败，如何撤消 npm set registry 命令

Question

我不小心在我的终端 npm set registry 上运行了这个命令：

• http://localhost:4873/
• https://www.npmjs.com/package/react-native-cli

在探索 react-native 时，它​​现在与我的 create-react-app yarn 命令（创建反应启动器应用程序）搞砸了，我知道这一点，因为我收到了这个错误

FetchError：对http://localhost:4873/yarn 的请求失败，原因：连接 ECONNREFUSED 127.0.0.1:4873 ...

关于如何修复它的任何建议。我的版本npm、yarn、node

• npm -v6.4.1
• 节点 v10.14.2
• yarn v1.12.3
• brew v1.8.6 homebrew-core#cdd30, homebrew-cask#580d7

这是我尝试重新安装 create-react-app cli 时的完整错误代码

npm install -g create-react-app yarn

我遇到了类似的问题，我注册了http（不安全）。对我有用。

$ npm config set registry http://registry.npmjs.org/
$ npm config set strict-ssl false

Answer 2

尝试删除~/.npmrc（如果存在）。当您运行 npm set registry 时，它通常会将设置保存到该文件中。
