如何使用 Pyinstaller 创建的可执行 python 解决“jinja2.exceptions.TemplateNotFound: html.tpl”

Question

我使用 Pyinstaller 为我的脚本创建了一个 exe，在运行该 exe 时它会引发以下错误，就好像我运行 .py 文件没有发现问题一样。

Traceback (most recent call last):
  File "myApplication.py", line 12, in <module>
  File "<frozen importlib._bootstrap>", line 983, in _find_and_load
  File "<frozen importlib._bootstrap>", line 967, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 677, in _load_unlocked
  File "PyInstaller\loader\pyimod03_importers.py", line 540, in exec_module

  File "jinja2\loaders.py", line 249, in get_source
jinja2.exceptions.TemplateNotFound: html.tpl
[18152] Failed to execute script myApplication

这里，[File "myApplication.py", line 12, in ] 在我的脚本中是 "import dataframe_image as dfi"。

我没有直接在我的脚本中使用 jinja2 模块。

我尝试了构建选项 --hidden-import=dataframe_image，它不适用于此问题。

Pyinstaller=4.3 Python=3.7.7

提前感谢您的帮助！

解决方案，pyinstaller --add-data path-to-site-packages\pandas\io\formats\templates\html.tpl;pandas\io\formats\templates 解决了上述错误，但出现了另一个错误。

Exception in Tkinter callback
Traceback (most recent call last):
  File "tkinter\__init__.py", line 1705, in __call__
  File "myApplication.py", line 374, in main
  File "dataframe_image\_pandas_accessor.py", line 24, in export

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\***\\AppData\\Local\\Temp\\_MEI252882\\dataframe_image\\static\\style.css'

这里，File "myApplication.py", line 374, in main 是 dataframe_image.export(style, 'myTable.png')

这是捆绑包中包含熊猫模板的问题。 pandas 开发团队报告了两个问题：

• https://github.com/pandas-dev/pandas/issues/39733
• https://github.com/pandas-dev/pandas/issues/38775

还有一个向 pyinstaller 团队报告：

• https://github.com/pyinstaller/pyinstaller/issues/5360

如果它对您不起作用，请检查此答案以解决问题：

这不是最好的，因为需要编辑熊猫代码，但无论如何。
