这是因为没有权限打开createinstallmedia，修改权限即可:
swaedeMacBook-Pro:~ swae$ chmod +x /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia
修改完成权限后，重置制作u盘启动即可：
/Volumes/Install macOS Catalina/ is not a valid volume mount point.
swaedeMacBook-Pro:~ swae$ sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Catalina/
Ready to start.
To continue we need to erase the volume at /Volumes/Catalina/.
If you wish to continue type (Y) then press return: Y
