Python 3.6-使用pyinstaller创建exe-错误

我正在寻找一种从pdf文件中获取文本的方法，并找到了一个pdfminer库，在github上有一个工作示例。 我稍微修改了它以传递参数，当我使用python执行脚本时，它工作得很好。但是我想要一个exe文件。 我使用pyinstaller创建了exe，不幸的是，当我尝试运行该文件时，出现以下错误：

Traceback (most recent call last):
  File "onlypdfminer.py", line 5, in <module>
  File "<frozen importlib._bootstrap>", line 971, in _find_and_load
