mac 创建React Native项目遇到的问题

React Native创建项目遇到的问题

1.创建项目时提示：

⠧ Processing templateUsage Error: The nearest package directory (/Users/huang/Documents/develop/RN/myRn) doesn't seem to be part of the project declared in /Users/huang.

- If /Users/huang isn't intended to be a project, remove any yarn.lock and/or package.json file there.

看提示是缺少yarn.lock文件，进到目录内创建一个yarn.lock

huang@huangdeMacBook-Pro RN % cd myRn                          
huang@huangdeMacBook-Pro myRn % touch yarn.lock   

2.创建项目时提示需要到ios目录执行 bundle install 、 bundle exec pod install 命令，执行 bundle install 后提示没有权限

huang@huangdeMacBook-Pro ios %  bundle install  
There was an error while trying to write to
`/Users/huang/.bundle/cache/compact_index/rubygems.org.443.29b0360b937aa4d161703e6160654e47/versions.15001.tmp`.
It is likely that you need to grant write permissions for that path.

.bundle/设置读写权限后，再执行就成功了。

huang@huangdeMacBook-Pro ios % sudo chmod -R 777 /Users/huang/.bundle/
Password:
huang@huangdeMacBook-Pro ios % bundle install  

3. bundle exec pod install 报错，是没有安装依赖引起的。

huang@huangdeMacBook-Pro ios % bundle exec pod install
[!] Invalid `Podfile` file: [!] /Users/huang/.nvm/versions/node/v20.12.0/bin/node -p require.resolve(
    "react-native/scripts/react_native_pods.rb",
    {paths: [process.argv[1]]},
  ) /Users/huang/Documents/develop/RN/myRn/ios

node:internal/modules/cjs/loader:1146
  throw err;
  ^

}

返回项目主目录，执行 yarn install 安装按成后，再回到ios目录， 执行bundle exec pod install命令，就可以正常安装了

huang@huangdeMacBook-Pro myRn % cd ..
huang@huangdeMacBook-Pro myRn % yarn install

huang@huangdeMacBook-Pro myRn % cd ios
huang@huangdeMacBook-Pro ios % bundle exec pod install
