由于我的gcc缺少标准库，我遇到了一个问题。

最初我有一个不同的问题。关于找不到类型 copying blpapi/schema.py -> build/lib.macosx-10.7-x86_64-3.7/blpapi

的事情。并且Sample screenshot from modal window建议删除uint8_t中的文件。这就是现在的原因。这是因为现在没有标准库。我安装了此/usr/local/include/，现在/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg中有标准库。我将其复制到/usr/include无济于事。 /usr/local/indclude/告诉我：
brew link gcc如何解决此问题？
