端口8081在“react-native run-ios”中已经在使用

是的我已经读过这个但仍然不知道如何使它工作.
react native – Port 8081 already in use, packager is either not running or not running correctly Command /bin/sh failed with exit code 2

最初我是这样做的

1. react-native init Hello
2. react-native run-ios

然后点击“已使用的端口8081”.

读过反应文件,https://facebook.github.io/react-native/docs/troubleshooting.html

1. cannot kill the process using 8081, it keeps on coming back,
   and i don't want to kill it
2. react-native start --port=8088
3. update node_modules/react-
native/React/React.xcodeproj/project.pbxproj file. Did it.

应该在哪里和哪一步运行“react-native start –port = 8088”？

顺便说一句,我是一名普通的工程师,但如果我不能在2小时内运行第一反应本机样本,我就看不出它是如何飞行的,这非常烦人.

在RN 0.55中,你可以解决这个问题：

react-native start –port = 1234

然后在另一个窗口：

react-native run-ios –port 1234

版本：

✗ react-native --version
react-native-cli: 2.0.1
react-native: 0.55.4
