from PIL import Image
from subprocess import Popen, PIPE
scr = Image.open(Popen.communicate(Popen(['import','-w','0x02a00001','png:-'], stdout=PIPE))[0])错误：
File "/usr/lib/python3/dist-packages/PIL/Image.py", line 2258, in open
fp = builtins.open(filename, "rb")

首先尝试将原始数据加载到BytesIO容器中：
from io import BytesIO
from PIL import Image
from subprocess import Popen, PIPE
data = Popen.communicate(Popen(['import','-w','0x02a00001','png:-'], stdout=PIPE))[0]
scr = Image.open(BytesIO(data))页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
