全新的 react/node.js 项目不会在 opensuse 上运行

Question

我目前正在学习 Express 和 react，并且最初能够运行 react 应用程序。在启动一个新的网络应用程序时（昨天），我无法阻止一个新创建的反应应用程序崩溃。

My OS:
openSUSE 20180522 <br>
Kernel: x86_64 Linux 4.16.9-1-default

错误：

$ npm start

 > movieapp@0.1.0 start 
 /home/knosence/Templates/syntelBootCamp/react/movieapp
 > react-scripts start

 Attempting to bind to HOST environment variable: linux-gz59
 If this was unintentional, check that you haven't mistakenly set it 
 in your shell.

如果有人能帮我解决这个问题，我们将不胜感激！！如果有人需要更多信息，请告诉我，我会提供。谢谢！

Answer 1

我遇到了同样的问题并使用

修复了它

HOST=localhost npm start

希望对其他人有所帮助！

Answer 2

你的机器可能有一个全局的 HOST 环境变量，所以 Create React App 会尝试在它上面找到一个开放的端口，而不是默认的 localhost。删除环境变量，它应该可以正常工作。

也许这个答案会对你有所帮助。
