Library not loaded: /opt/homebrew/opt/icu4c/lib/libicui18n.71.dylib

报错

dyld[98585]: Library not loaded: /opt/homebrew/opt/icu4c/lib/libicui18n.71.dylib  Referenced from: /opt/homebrew/Cellar/php@7.0/7.0.33_6/bin/php  Reason: tried: '/opt/homebrew/opt/icu4c/lib/libicui18n.71.dylib' (no such file), '/usr/local/lib/libicui18n.71.dylib' (no such file), '/usr/lib/libicui18n.71.dylib' (no such file), '/opt/homebrew/Cellar/icu4c/70.1/lib/libicui18n.71.dylib' (no such file), '/usr/local/lib/libicui18n.71.dylib' (no such file), '/usr/lib/libicui18n.71.dylib' (no such file)[1]    98585 abort      php -v

查看了/opt/homebrew/opt/icu4c/lib/目录下是libicui18n.70.dylib

第一次解决

$brew switch icu4c 71Error: Unknown command: switch

回滚

#切换目录cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula #git查看提交版本git log --follow icu4c.rb #回滚到71版本，没有看到71的提交记录，选择了最初的一个提交版本回滚git checkout -b icu4c-71.1 xxxx(版本号) #brew重新安装icu4cbrew reinstall ./icu4c.rb

失败
又参考了记录一次brew 回滚 icu4c 操作仍然不行

最后解决

brew update && brew upgrade
