javascript - React-Native(构建失败)

Question

我正在尝试构建一个 React native 应用程序，但我似乎总是遇到许多开发人员目前面临的相同问题。创建应用后

1. react-native init HelloWorld
2. cd HelloWorld
3. react-native run-ios(进入终端)

弹出这样的错误并终止运行:

** BUILD FAILED **


The following commands produced analyzer issues:
	Analyze /Users/JemmaMarie/Documents/CareerCenter/Exercises/Ex_Files_Learning_React_Native/Exercise\ Files/Ch02/start/HelloWorld/node_modules/react-native/ReactCommon/yoga/yoga/YGNodeList.c

(2 commands with analyzer issues)

The following build commands failed:

我已经尝试过堆栈溢出的这些解决方案，但没有成功: 环境:

节点:8.2.1 守望者:4.7.0 代码:8.3.3 react native cli:2.0.1 react native :未知

1. 升级的 xCode 现在版本8.3.2

2. 升级了 react native 并再次运行 react native run-ios

3. 转到系统首选项并在 xcode IDE 上选择 xcode 版本

4. 我删除了 node_modules 以查找另一个人发现的“拼写错误”并运行了 react-native run-ios 但仍然不起作用

5. 尝试使用 rm -r 删除构建文件夹 ios/build 并运行 react-native run-ios

6. 按照 https://github.com/facebookincubator/create-react-app 的步骤尝试了另一个样板文件 create-react-native-app HelloWorld

但是得到这个错误:

module.js:487
    throw err;
    ^

Error: Cannot find module 'semver'

    at Module.load (module.js:503:32)
    at tryModuleLoad (module.js:466:12)
    at Function.Module._load (module.js:458:3)

到目前为止，有没有人找到一个非常可靠的解决方案？

提前致谢。

我遇到了那个错误，我通过了这些步骤，终于成功构建了。

1) delete 'ios' and 'android' folder.
2) delete 'node_module'
3) npm i
4) react-native eject
5) react-native-git-upgrade  #this step is important
6) react-native run-ios
