PyScreeze崩溃: OSError: winll.gdi32.GetPixel失败:返回-1

试图检查像素的颜色：
while True:
x, y = 1742, 979
r,g,b = pyautogui.pixel(x, y)
if b == 106:
#some more code完整的回溯：

raise WindowsError("windll.gdi32.GetPixel failed : return {}".format(color))
OSError: windll.gdi32.GetPixel failed : return -1
During handling of the above exception, another exception occurred:

OSError: windll.user32.ReleaseDC failed : return 0公认的答案here说：“这是PyScreeze 0.1.28中已经解决的问题，所以您只需要通过运行pip install -U pyscreeze来更新它。”
我上的是PyScreeze 0.1.28，所以不是这样的。公认的答案here谈到手动释放所有DC，但当我直接使用.pixel函数而不是win32时，我不知道如何做到这一点。

解决方法，直到管理包的人回复。不修复错误，只需使用try和except处理它。

if b == 106:
#some more code
except:
x, y = 1742, 979
r,g,b = pyautogui.pixel(x, y)
if b == 106:
