如何在更新和升级 Homebrew 后修复丢失的库

Question

我决定在周五下午更新和升级 Homebrew（因为为什么不呢），它似乎导致缺少一个库，这影响了我运行几乎所有东西的能力（PHP , Laravel Valet, Node, etc...) 每个错误信息都是一样的，所以我希望这是一个简单的修复，但我不确定从哪里开始。

他们似乎都在寻找 /usr/local/opt/icu4c/lib/libicui18n.61.dylib

中的图书馆

** 编辑 **

我运行 Styx 建议的 brew 命令，这里是输出：

Chriss-MacBook-Pro-2:~ chris$  brew link icu4c
Warning: Refusing to link macOS-provided software: icu4c
If you need to have icu4c first in your PATH run:
  echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
  echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.bash_profile

For compilers to find icu4c you may need to set:
  export LDFLAGS="-L/usr/local/opt/icu4c/lib"
  export CPPFLAGS="-I/usr/local/opt/icu4c/include"

将 icu4c 添加到我的路径很容易，但我不确定如何处理要求我设置

的第二部分

** 更新 **

这是运行ning ls -l /usr/local/opt/icu4c/lib/

的输出

Answer 1

看来你的icu4c已经升级了，但是你的php/node仍然是旧版本。

您可以：

重新安装依赖[=12=]的软件:

brew uses --installed icu4c | xargs brew reinstall

切换到使用旧版本 icu4c:
```
brew switch icu4c 61.2
```
