最近在运行ernibe-bot researcher的时候出现了下面的问题：
OSError: no library called "cairo-2" was found
no library called "cairo" was found
no library called "libcairo-2" was found
cannot load library 'libcairo.so.2': dlopen(libcairo.so.2, 0x0002): tried: 'libcairo.so.2' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibcairo.so.2' (no such file), '/Users/wugaosheng/miniconda3/envs/researcher39/bin/../lib/libcairo.so.2' (no such file), '/usr/lib/libcairo.so.2' (no such file, not in dyld cache), 'libcairo.so.2' (no such file), '/usr/local/lib/libcairo.so.2' (no such file), '/usr/lib/libcairo.so.2' (no such file, not in dyld cache). Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo.so.2'
解决方法
conda install cairo pango
