import PIL.ImageGrab

im = PIL.ImageGrab.grab()
im.show()

在Pycharm中工作，不构成命令行。尝试了很多事情，可以在下面看到，不确定还有什么要改变的。

C:\Users\a.b>C:\Users\a.b\AppData\Local\Continuum\anaconda3\python.exe C:\Users\a.b\PycharmProjects\emlekezteto\screenshot.py

我检查过的事情：

1. Pycharm解释器是相同的。在Pycharm和命令行中：

C:\Users\a.b\AppData\Local\Continuum\anaconda3\python.exe 

2.即使工作目录相同，即将下面的内容放在代码中，仍然是相同的问题。默认情况下，这是在Pycharm中运行表单时的工作目录。

os.chdir(r'C:\Users\a.b\PycharmProjects\emlekezteto') 

3.对于Pycharm，sys.path是不同的：

['C:\\Users\\a.b\\PycharmProjects\\emlekezteto', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\pydev', 'C:\\Users\\a.b\\PycharmProjects\\emlekezteto', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\pycharm_display', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\third_party\\thriftpy', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\pydev', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\python37.zip', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\DLLs', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3', 'C:\\Users\\a.b\\AppData\\Roaming\\Python\\Python37\\site-packages', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32\\lib', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\Pythonwin', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\pycharm_matplotlib_backend', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\IPython\\extensions', 'C:\\Users\\a.b\\PycharmProjects\\emlekezteto', 'C:/Users/a.b/PycharmProjects/emlekezteto']

在cmd中：

['', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\python37.zip', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\DLLs', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3', 'C:\\Users\\a.b\\AppData\\Roaming\\Python\\Python37\\site-packages', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32\\lib', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\Pythonwin']

即使当我用硬编码在代码中的所有Pycharm sys.path扩展sys.path时，它仍然会给出相同的错误。

 import os
    print (os.getcwd())
    os.chdir(r'C:\Users\a.b\PycharmProjects\emlekezteto')
    print (os.getcwd())

    import sys; print(sys.path)

sys.path.extend(['C:\\Users\\a.b\\PycharmProjects\\emlekezteto', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\pydev', 'C:\\Users\\a.b\\PycharmProjects\\emlekezteto', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\pycharm_display', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\third_party\\thriftpy', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\pydev', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\python37.zip', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\DLLs', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3', 'C:\\Users\\a.b\\AppData\\Roaming\\Python\\Python37\\site-packages', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32\\lib', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\Pythonwin', 'C:\\Program Files\\JetBrains\\PyCharm 2019.3\\plugins\\python\\helpers\\pycharm_matplotlib_backend', 'C:\\Users\\a.b\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\IPython\\extensions', 'C:\\Users\\a.b\\PycharmProjects\\emlekezteto', 'C:/Users/a.b/PycharmProjects/emlekezteto'])

    print (sys.path)
    import PIL.ImageGrab
    im = PIL.ImageGrab.grab()
    im.show()
