serve -s build 指定端口号 [英] serve -s build specify port number

问题描述

我正在尝试从 DigitalOcean droplet 提供 react-app 的构建文件夹.

I'm trying to serve a react-app's build folder from a DigitalOcean droplet.

运行 yarn build 后，脚本告诉我运行

After I run yarn build, I get told by the script to run

yarn 全局添加服务服务 -s 构建

但是，当我运行 serve -s build 时，它说它在 http://localhost 上运行:5000.我希望它在 localhost:3000 上运行，因为我有另一台服务器在端口 5000 上运行.如何指定端口号，以便 serve -s build 在端口 3000 上运行?

However, when I run serve -s build, It say's it's running on http://localhost:5000. I would like it run on localhost:3000 instead, as I have another server running on port 5000. How can i specify the port number such that serve -s build runs on port 3000?

推荐答案

从输入serve --help，我发现

-l, --listen listen_uri            
Specify a URI endpoint on which to listen

For TCP ports on hostname "localhost":

$ serve -l 1234

在你的情况下，你可以使用

In your case, you can just use

serve -l 3000 -s build

指定您要在端口 3000 上提供应用程序

to specify that you want to serve the app on port 3000
