can't find gem cocoapods (>= 0.a) with executable pod (react-native pod install)

I just start a react-native project. However, this question had me for a day.I tried all possible way to solve it. For example,

sudo gem uninstall cocoapodsrvm uninstallbrew install cocoapods

However, there is no luck for me.I would like to point out that I can pod --version under other path but issue occur when I try to pod under my project path. I also tried to set rvm default version to 2.7.5 but issue still happen.Also, I am not using Apple M1
