Textract：失败，退出代码127 // Windows 10 // pdftotext

问题描述

当我尝试运行我的程序（使用pyinstaller部署后）时，用于读取和转换PDF文件并将其输入到Google工作表中。我收到下图中显示的错误。但是我似乎无法弄清楚问题出在哪里：

Exception in Tkinter callback
Traceback (most recent call last):

During handling of the above exception,another exception occurred:

解决方法

您似乎得到了FileNotFoundError。如果您看到此错误，则正在运行的命令是：

pdftotext //Mac/Home/Desktop/Wickey Einkauf Test/Rekeningen/Lekkerkerker_ - 
 0803471.pdf -

在这里我要看几件事。首先，在文件路径的开头有一个额外的斜杠，这似乎是错误的。其次，文件路径中有空格，但是路径中没有引号。第二部分意味着pdftotext将把它读为几个单独的命令参数，而不是一个。您可以通过格式化子流程调用的格式来解决此问题，以使文件用引号引起来，如下所示：

pdftotext "example file path.pdf" -

,

您需要使用pip安装pdftotext。 要安装它，您需要具有Microsoft Visual C ++ 14或更高版本。
