preface

This article is not a complete installation of Cocoapods, but rather an analysis of some of the error messages. At present, I have only a little knowledge and may not be able to provide you with a correct and effective solution.

Having been working on iOS for a few years, Cocoapods is naturally one of the must-have development components on your computer. Every time you change a computer, you need to go through the installation process again. Roughly, it has been installed for at least 5 times. Although each time is not very smooth, there are all kinds of warnings and errors, but with the help of the search engine to complete the installation, and then enter the subsequent development process. But this one was special, and it made me doubt my life.

The development environment

  • OS: macOS Catalina 10.15.7

  • Xcode: 12.4 (12 d4e)

  • CocoaPods

    • Podfile.lock: 1.9.1 (the lowest version of pod required by the project)
    • Currently installed POD: 1.5.2
    • Purpose: You need to upgrade the local POD version, at least1.9.1Can only be
