#测试办法：
go install sigs.k8s.io/controller-tools/cmd/controller-gen@v0.9.0

Had the same issue using wsl, completely remove go and reinstall solves the problem

sudo rm -rf /usr/local/go
自己去/home下remove path from .bashrc
sudo tar -C /usr/local -xzf go1.20.6.linux-amd64.tar.gz
#add PATH back to .bashrc solves the problem
#在linux中，bashrc文件在“/home”目录下，也即用户的主目录下；该文件是一个隐藏文件，用于存储并加载系统的终端配置和环境变量，可以用“ls -a”命令查看，用“find -name .bashrc”命令查找文件在什么位置。
