reactjs - ruby 错误模棱两可的选项：-s (OptionParser::AmbiguousOption) 服务反应应用程序时

问题描述

为什么在尝试运行我的 react-app 的构建时出现此错误？

尝试为我的 React 应用程序提供“构建”服务时出现以下错误：

命令：

serve -s build

返回：

Traceback (most recent call last):
        4: from -e:1:in `<main>'
        3: from /Users/johnelbasha/.rbenv/versions/2.6.6/lib/ruby/2.6.0/un.rb:324:in `httpd'
        2: from /Users/johnelbasha/.rbenv/versions/2.6.6/lib/ruby/2.6.0/un.rb:41:in `setup'

在收到此错误之前，我使用了以下命令：

命令：

npm run build

返回：

> my-app@0.1.0 build /Users/johnelbasha/code/my-app
> react-scripts build

The project was built assuming it is hosted at /.
You can control this with the homepage field in your package.json.

The build folder is ready to be deployed.
You may serve it with a static server:

  yarn global add serve
  serve -s build

解决方案

如果你\在它之前运行它，它会工作，因为它将运行非别名serve（你的纱线之一）

\serve -s 构建
