npm 命令 create-react-app 失败

Question

我正在尝试在运行 OsX sierra 10.12.6 的计算机（mbp pro 2017）上测试 reactjs。我遵循了 Facebook 教程：

1. 确保您安装了最新版本的 Node.js。（完毕）
2. 按照安装说明创建一个新项目。https://facebook.github.io/react/docs/installation.html#creating-a-new-application

但是我在这第二步上遇到了问题！

• 我不支持代理。
• 我的网络没问题。
• 存储库设置为 registry.npmjs.org
• 我可以阅读网址：https : //registry.npmjs.org/create-react-app
• 但是即使在外部 DNS wsg.intra.corp.grp上也找不到该域

我被卡住了，任何帮助都会很好！

Answer 1

正如wsg.intra.corp.grp:8080日志中提到的那样，您似乎在公司代理后面。

您需要像本指南中显示的那样配置代理。

希望这可以帮助！

Answer 2

在命令提示符下运行以下命令。确保已安装 Node 和 npm。

npm config rm proxy

npm config rm https-proxy

在浏览器中打开此链接：https ://registry.npmjs.org/

运行以下命令来设置注册表。

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

希望有帮助:)
