我在 Ubuntu 18.10 上使用 mss 时遇到错误(如果重要的话)。这是我的代码(取自他们在文档中的示例,加上一些额外的错误输出):
import mss
with mss.mss() as sct:
try:
filename = sct.shot(mon=-1, output='fullscreen.png')
print(filename)
except Exception as e:
print(e, "\n", e.details)
这是我使用 python 3.7 运行代码时看到的输出。
XGetImage() failed
{'retval': <mss.linux.LP_XImage object at 0x7fc72d567bf8>, 'args': (<mss.linux.LP_Display object at 0x7fc72db7d1e0>, <mss.linux.LP_Display object at 0x7fc72d567950>, 0, 0, 1920, 1080, 16777215, 2)}
如果它有帮助,如果我没有捕获异常,这里是输出(stacktrace)
Traceback (most recent call last):

我在虚拟环境中运行它,其中我的 Pipfile.lock 报告 mss version 4.0.2
。
我曾尝试以 root 身份运行它,但给出了相同的输出。我无法在 Google 中找到类似的问题。我还尝试在 tmux 之外运行它,但也没有结果。
