Pyinstaller - 找不到 Flask 模板“bootstrap/base.html”

Question

我正在尝试制作一个可分发的烧瓶应用程序。在本地运行时一切正常。当使用 pyinstaller 生成可执行文件时，它会给我错误：

 Traceback (most recent call last):
  File "site-packages\flask\app.py", line 2446, in wsgi_app

  File "site-packages\flask\app.py", line 1951, in full_dispatch_request
  File "site-packages\flask\app.py", line 1820, in handle_user_exception

  File "site-packages\flask\templating.py", line 120, in _render
jinja2.exceptions.TemplateNotFound: bootstrap/base.html

我正在使用烧瓶引导程序，如图所示here。

创建一个名为“hook-flask_bootstrap.py”的新python文件，在此粘贴以下内容：

from PyInstaller.utils.hooks import collect_data_files
datas = collect_data_files('flask_bootstrap')

现在，当您运行 pyinstaller 时，请提供此“hook-flask_bootstrap.py”文件的路径：

--additional-hooks-dir=PATH (If relative path, just use .)
