npm 命令 create-react-app 失败

Question

我正在尝试在我的计算机上测试 reactjs (mbp pro 2017) 运行 OsX sierra 10.12.6。我已遵循 Facebook 教程：

确保您安装了 Node.js 的最新版本。 （完成）
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

但是我在第二步遇到了问题！

我没有使用代理。
我的网络没问题
存储库设置为 registry.npmjs.org
我可以阅读 url : https://registry.npmjs.org/create-react-app
但是即使在外部 DNS 上也找不到这个域 wsg.intra.corp.grp

我被卡住了，任何帮助都会很好！

Answer 1

您似乎在使用公司代理，正如日志中提到的 wsg.intra.corp.grp:8080。

您需要像 this guide 中所示配置代理。

希望对您有所帮助！

Answer 2

在 Github 上关注 this post，并在我的 /etc/hosts 中添加“104.18.95.96 registry.npmjs.org”解决了我的问题。

Answer 3

如果您仍然遇到问题，请按照以下步骤操作：

转到“设置”>“网络和 Internet”>“代理”并找出地址和端口
根据您的机器转到命令提示符或终端（提示：按 Win + R 并键入 cmd）。在命令提示符中键入以下命令

npm 配置设置代理 http://usernamepassword@proxy-server-url:port

npm 配置设置 https 代理 http://usernamepassword@proxy-server-url:port

10 次中有 9 次确实不需要用户名和密码，最后 2 次就足够了。 Proxy-server-url是你的地址，你的端口是端口号。一旦设置关闭命令提示符并重新打开它。瞧！您现在可以安装所有软件包

Answer 4

我解决了这个问题，转到设置 > 网络和 Internet > 代理，然后在 Windows 上的自动代理设置下关闭自动检测设置。然后安装正常。

Answer 5

运行命令提示符下的命令。确保安装了 node 和 npm。

npm config rm proxy

npm config rm https-proxy

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

运行下面的命令设置注册表。

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