PyInstaller ImportError：DLL 加载失败

【问题标题】：PyInstaller ImportError: DLL load failedPyInstaller ImportError：DLL 加载失败
【发布时间】：2017-07-24 16:57:17
【问题描述】：

我对 Python 还是很陌生。我正在使用：

  • Windows 10、64 位
  • Python 3.5.3
  • PyInstaller 3.2.1

我尝试使用 PyInstaller 打包我的第一个 GUI 测试应用程序。我用过

pyinstaller --onedir testgui.py

为此。生成的应用程序没有运行。当我尝试通过命令提示符运行.exe 文件时，它返回了以下消息：

C:\PythonProjects\firstGUI\dist\testgui>testgui.exe
Traceback (most recent call last):
  File "site-packages\PyInstaller\loader\rthooks\pyi_rth_qt5plugins.py", line 46, in <module>
  File "c:\users\xyz\appdata\local\programs\python\python35\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 573, in load_module
    module = loader.load_module(fullname)
ImportError: DLL load failed: [Module not found in german....] .
Failed to execute script pyi_rth_qt5plugins

这些是我在非常短的脚本中所做的所有导入：

import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *

我做错了什么？如果有帮助，我可以发布我在打包过程中收到的所有警告行。

编辑：

在打包过程中，我在日志中收到了一些 WARNING: lib not found 条目。这是完整的打包日志：

【问题讨论】：

  • github.com/pyinstaller/pyinstaller/wiki/If-Things-Go-Wrong
  • @StephenRauch 谢谢，但我已经看过了，并没有发现它很有帮助。也许我只是没有足够的经验，也许我只是厚，但我不知道如何确切地“使用 .spec 文件”或“实现一个新的钩子”。我将不胜感激任何帮助我的实际尝试。我以前从未这样做过。
  • 好的，我可以尝试提供帮助，但需要链接中注明的具体信息。在上述情况下，它无法找到 DLL。您是否在构建的同一台机器上运行？还要知道 QT 是通常难以正确处理的模块之一。还建议您查看 pyinstaller 错误跟踪器，看看是否有任何对您的情况有价值的东西。
  • @StephenRauch 感谢您的尝试！是的，我试图在我构建它的同一台机器上运行它。该程序本身在 Python 中运行良好。它实际上只是一个带有一些文本字段和几个按钮的小部件。我在上面的原始帖子下方发布了包装日志。我将尝试检查所有内容是否按照他们网站上描述的方式打包并报告。

【解决方案1】：

在您的驱动器上搜索丢失的文件并将其文件路径添加到您的环境变量路径数据（控制面板→系统→高级系统设置→环境变量）或构建：

pyinstaller --paths yourpathshere app.py

比如我的项目找到Qt5Core.dll和co如下：

pyinstaller --paths C:\Users\MYUSERNAME\AppData\Local\Programs\Python\Python35-32\Lib\site-packages\PyQt5\Qt\bin app.py

【讨论】：

  • 我遇到了与 OP 相同的问题并尝试搜索这些文件，但在系统上找不到它们。
