我尝试运行sudo ARCHFLAG=-Wunused-command-line-argument-hard-error-in-future pip install Pillow，但它失败了，输出如下：
cc -bundle -undefined dynamic_lookup -arch x86_64 -arch i386 -Wl,-F. build/temp.macosx-10.9-intel-2.7/_imaging.o build/temp.macosx-10.9-intel-2.7/decode.o ... continued ...

clang: error: no such file or directory: 'build/temp.macosx-10.9-intel-2.7/decode.o'
...etc...
