macOS 10.12升级到icu4c 67.1失败

如何解决macOS 10.12升级到icu4c 67.1失败

我使用的是较旧的iMac，无法将macOS升级到10.12以上。 当我冲煮升级fontforge时，它在升级的fontforge依赖项icu4c上失败。以下是部分日志。

Google搜索没有返回太多信息，任何人都有类似的问题并且知道如何解决它？

==> Installing fontforge dependency: icu4c
==> ./configure --prefix=/usr/local/Cellar/icu4c/67.1 --disable-samples --disable-tests --enable-static --with-library-bits=64

解决方法

好吧，似乎有一个为此lib提供更新公式的分支：https://github.com/dotysan/homebrew-core/tree/icu4c-cplusplus14，我能够安装它来克隆该分支（您实际上只能下载所需的公式），并明确将brew指向该版本：

git clone https://github.com/dotysan/homebrew-core/
cd homebrew-core/
git checkout -b icu4c-cplusplus14 origin/icu4c-cplusplus14
brew reinstall --build-from-source ./Formula/icu4c.rb
