brew update
brew upgrade
brew install go --cross-compile-common

英文:
Try running
brew update
brew upgrade
brew install go --cross-compile-common

brew update 可能会警告您有多个过时的库，所以：
如果您想检查所有过时的库：
brew update
brew outdated
要升级单个库（比如这个例子中的 go）：
brew update
brew upgrade go
要升级所有库：
brew update
brew upgrade
英文:
brew update may warn you about multiple outdated libraries, so:
if you want to check ALL outdated libraries:
brew update
brew outdated
To upgrade a SINGLE library (like go in this case):
brew update
brew upgrade go
To upgrade ALL libraries:
brew update
brew upgrade
