python - 文本摘要 : failed with exit code 127//windows 10//pdftotext

Question

当我尝试运行我的(在使用 pyinstaller 部署之后)程序以读取和转换 PDF 文件并将其输入到 google 表格中时。我收到下图中显示的错误。但是我似乎无法弄清楚问题是什么:

Exception in Tkinter callback

During handling of the above exception, another exception occurred:

Answer 1

您似乎遇到了 FileNotFoundError。如果您查看错误，正在运行的命令是:

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

这里有几件事我会看看。首先，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，但路径中没有引号。这第二部分意味着 pdftotext 会将其读取为几个单独的命令参数，而不是一个。您可以通过格式化子进程调用以将文件用引号括起来来解决此问题，如下所示:

pdftotext "example file path.pdf" -
