我一直在寻找这个问题的答案，但找不到，所以就在这里。 我正在尝试使用以下方式将tesserocr安装到MacOS X Mojave（Python 3.6）中：
$ pip install tesserocr
然后我得到以下错误：
gcc -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3 -Wall
-Wstrict-prototypes -I/anaconda3/include -arch x86_64 -I/anaconda3/include -arch x86_64

P.s。我已经安装了最新版本的Xcode和Xcode CLI。
谢谢。
