pod trunk push --allow-warnings 更新报错
找到的解决方案是：
解决方案就是去xcode设置里面，将Command line Tools设置一下，在Xcode>preferences>Locations里面，设置之后再运行终端即可
但是
操作失败！
选择框下面的提示：
Command line tools like 'xcodebuild will use this version of the tools. Change this setting above or use 'xcode-select' from the command line.
终端
查看当前使用xcode版本路径
xcode-select -p /Library/Developer/CommandLineTools
查看xcode-select 版本
xcode-select -v xcode-select version 2354.
重置默认的command line tools
xcode-select -r xcode-select: error: --reset must be run as root (e.g. sudo xcode-select --reset).
切换
sudo xcode-select -s /Applications/Xcode9.4.1.app
更多的命令
xcode-select -h
Usage: xcode-select [options]
Print or change the path to the active developer directory. This directory
controls which tools are used for the Xcode command line tools (for example,
xcodebuild) as well as the BSD development commands (such as cc and make).
Options:
| -h, --help | print this help message and exit |
| -p, --print-path | print the path of the active developer directory |
| -s
| set the path for the active developer directory |
| --install | open a dialog for installation of the command line developer tools |
| -v, --version | print the xcode-select version |
| -r, --reset | reset to the default command line tools path |
