react native笔记-个人记录-初始化工程遇到的问题

使用Expo工具

在mac上安装expo，如果是权限问题可以参考以下解决方法
https://blog.csdn.net/testcs_dn/article/details/78869419
https://jingyan.baidu.com/article/9c69d48ff88b3813c9024e9d.html

这是第二条链接的说明：对于Mac OS X 10.11 El Capitan用户，由于系统启用了SIP(System Integrity Protection), 导致root用户也没有权限修改/usr/bin目录。按如下方式可恢复权限。
屏蔽方法：重启Mac，按住command+R,进入recovery模式。选择打开Utilities下的终端，输入：csrutil disable并回车，然后正常重启Mac即可。

报错： react native fsevents unavailable (this watcher can only be used on Darwin)

解决的办法参考链接
npm r -g watchman
brew install watchman
注意：这里我使用npm install watchman还是有问题的，但是换成brew安装后没有问题

react-native run-ios报错

Could not find iPhone 6 simulator参考链接

Command+shift+.可以显示/隐藏以"."开头的文件或者文件夹

解决 React-Native mac 运行报错 error Failed to build iOS project. We ran “xcodebuild” command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app, by ope

地址，如果按照以上的还有问题使用sudo跑下https://www.cnblogs.com/stevexu/archive/2019/04/21/10745769.html

如果显示像下面图片一样，但是模拟器没有安装程序，可能需要kill一下进程，下面的链接很详细的说明了各种情况

解决升级到Xcode10，react native项目运行报错问题

我遇到的错误是下面这个或者没有config.f的，**

这个链接很有用**

错误一：Xcode 10: Build input file double-conversion cannot be found
error: Build input file cannot be found: '../node_modules/react-native/third-party/double-conversion-1.1.6/src/strtod.cc'
configure: error: in `../node_modules/react-native/third-party/glog-0.3.4'

完美解决：＂library not found for - ＂

该文章提供了很多的解决方案：https://blog.csdn.net/liujia216/article/details/53112709
我也遇到了该问题，但是项目的这个库是别人封装的，所以我暂时是把该库移除了

修改模拟器

react-native run-ios --simulator "iPhone X" //iPhone X是需要使用的模拟器

真机调试链接

真机调试查看连接的设备

adb devices

注意：需要确保你的电脑和手机设备在同一个Wi-Fi环境下，要不然我的会出现闪退
真机调试修改和查看

把就项目放到android studio报错

Error:(24, 0) Could not find method implementation() for arguments [directory ‘libs’] on object of t

这种方式会有警告，告诉你compile过时了，你可以选择升级gradle，解决链接

Android Studio 报错：Could not find com.android.support:appcompat-v7:28.0.0-beta01.

加上google()，解决链接

AManifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).Suggestion: add ‘`tools:replace="android:appComponentFactory`"’ to element at AndroidManifest.xml:5:5-20:19 to override.
