How to Solve Cocoapods Installation Failure

The scene appears

Recently, I replaced a 512 large hard disk and re installed MacOS 10.15. When installing cocoapods, the following error occurred

Building native extensions. This could take a while...
ERROR:  Error installing cocoapods:
    ERROR: Failed to build gem native extension.

Solution:

    1. it may be the problem of system version, which is not compatible with the latest version, so install the old version directly. I encountered the problem is 2021.07.06, the latest version is 1.10.1, find a 1.9.32020.05 release, should be compatible with 10.15
# Specify version to install
sudo gem install -n /usr/local/bin cocoapods -v 1.9.3
      1. use brew to install
brew install cocoapods
