Question

我是React-native的新手，并试图使用Windows版Android Studio中的本地本机构建android应用。安装react-navigation之后，请按照react-navigation文档中的所有步骤操作，运行react-native run-android，然后在命令行中收到此错误：

PS C:\Users\comp\Desktop\work\reactnative\dansapp> react-native run-android
Starting JS server...
Building and installing the app on the device (cd android && gradlew.bat installDebug)...

FAILURE: Build failed with an exception.

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

有人知道这个错误是什么以及如何解决？按照以下步骤安装react-navigation之后，似乎会发生这种情况：https://reactnavigation.org/docs/en/getting-started.html

我已经遵循了这些步骤，包括更改mainActivity.java文件。我也不知道gradle是什么。

任何帮助将不胜感激！

已知的问题（请参阅：bug with react-native link in android and windows），有望很快得到解决。

跳转到 / dansapp / android / 中的settings.gradle文件并替换...

<template>
  <div class="console" v-html="html">
  </div>
</template>

<script>
import AnsiUp from 'ansi_up'

export default {
  name: 'shell',
  props: ['socket'],
  data () {
    return {
      ansi: undefined,
      content: ''
    }
  },
  computed: {
    html () {
      // Ensures we have some semblance of lines
      return this.ansi.ansi_to_html(this.content).replace(/\n/gm, '<br>')
    }
  },
  watch: {
    socket () {
      this.socket.on('data', data => {
        this.content += data
      })
      this.socket.send('ready')
    }
  },
  beforeMount () {
    this.ansi = new AnsiUp()
  },
  updated () {
    // auto-scroll to the bottom when the DOM is updated
    this.$el.scrollTop = this.$el.scrollHeight
  }
}
</script>

<style lang="scss" scoped>
.console {
  font-family: monospace;
  text-align: left;
  background-color: black;
  color: #fff;
  overflow-y: auto;
}
</style>

...与...

project(':react-native-gesture-handler').projectDir = new File(rootProject.projectDir, '..\node_modules\react-native-gesture-handler\android')

安装React Navigation和手势处理程序后发生错误
