我正在尝试将包含模块pdftotext的python脚本转换为独立的.exe。当我在我的anaconda环境中测试.exe应用程序时，它工作正常，但当我在另一台设备上测试它时，它会给我这个错误：
File "main.py", line 3, in <module> #line 3 is import pdftotext
"ImportError: DLL load failed: The specified module could not be found"
[7300] Failed to execute script main
我确信这个问题与模块pdftotext有关，因为我尝试了下面的简单脚本，并且工作正常：
a=input("Start")
print("Hello world")
b=input("End")
如果我转换这个脚本，就会出现错误：
import pdftotext
a=input("Inserisci")
print("Hello world")
b=input("Fine")
对不起，我的英语不好，我来自意大利。我希望我能把自己说清楚，感谢的每一个人
编辑1。我发现问题可能与poppler(pdftotext使用的库(有关，但目前我不明白哪个文件连接到导入poppler
编辑2。经过一些工作，我发现了两件可能有助于更好地了解我的情况的事情：
.exe应用程序在我的设备上运行(甚至在我安装了poppler和pdftotext的anaconda env之外(，但在其他设备上不运行(我尝试了两台不同的windows笔记本电脑，错误相同(；没有"pdftotext"的脚本在每个设备上工作
在dist文件夹(由pyinstaller构建(中，出现一个包含名称pdftotext：文件是"pdftotext.cp37-winamd64.pyd"(我是不确定是什么(。在我的anaconda env中只有两个文件包含字符串"pdftotext"：文件为"pdftotext.cp37-win_amd64.pyd"one_answers"pdftotext.exe">
编辑3在不同的设备上运行main.exe时出现完全错误：
Traceback (most recent call last):
File "main.py",line 1, in <module>
ImportError: DLL load failed: The specified module could not be found
[7140] Failed to execute script main

您需要的是PyInstaller的挂钩文件。引用文件：
总之，一个"hook"文件扩展了PyInstaller，使其适应Python包所使用的特殊需求和方法。。。它们帮助分析阶段查找所需的文件。
官方钩子文档可以在https://pyinstaller.readthedocs.io/en/stable/hooks.html.
编辑：以下操作应该有效：
创建此目录结构：
- yourcode.py
- hooks
- hook-pdftotext.py
在挂钩文件中放入以下内容：
from PyInstaller.utils.hooks import collect_all
datas, binaries, hiddenimports = collect_all('pdftotext')
然后构建：
$ pyinstaller --additional-hook-dir=hooks yourcode.py
