React native 安装问题

这周打算玩下React native  , 真是看着官方教程简单,安装起来各种问题,属于是把坑踩完了,

完全不知道这玩意儿这么累,几次都想放弃了,

这里记录一下自己的采坑

1.安装用最新版的,要配置JDK11

2.安装源速度慢,那就必须得切换,不然就速度非常慢

在你的C盘 C:\Users\34300\.gradle 创建一个文件 init.gradle,配置了之后下载就很快了,可是第一次也没跑起来,第二次才跑起来

allprojects{
    repositories {
        def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/central/'
        def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/public/'
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('http://repo1.maven.org/maven2')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                    remove repo
                }
                if (url.startsWith('https://jcenter.bintray.com/') || url.startsWith('http://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                    remove repo
                }
            }
        }
        maven {
            url ALIYUN_REPOSITORY_URL
            url ALIYUN_JCENTER_URL
			url 'https://maven.aliyun.com/repository/google/'
			url 'https://maven.aliyun.com/repository/gradle-plugin/'
        }
    }
 
 
    buildscript{
        repositories {
            def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/central/'
            def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/public/'
            all { ArtifactRepository repo ->
                if(repo instanceof MavenArtifactRepository){
                    def url = repo.url.toString()
                    if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('http://repo1.maven.org/maven2')) {
                        project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                        remove repo
                    }
                    if (url.startsWith('https://jcenter.bintray.com/') || url.startsWith('http://jcenter.bintray.com/')) {
                        project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                        remove repo
                    }
                }
            }
            maven {
                url ALIYUN_REPOSITORY_URL
                url ALIYUN_JCENTER_URL
				url 'https://maven.aliyun.com/repository/google/'
				url 'https://maven.aliyun.com/repository/gradle-plugin/'
            }
        }
    }
}

 3.安装模拟器会占用C盘,C盘尽量腾出地方来,我记得是大于7G

反正是一番折腾
