I met this problem too. How to solve it?

Hi,
I also met this problem. After hours of debugging, I found the error may lie in the orgnization of the project. In my case, I created the __inti__.py in a folder to make it as a package（say my_package). When I using a module in this package (say my_module), I forgot to add the package name when writing the import statement.

Specificlly, I wrote from my_module import my_function , but the right way is from my_package.my_module import my_function.

Hope it helps.

Flask-Bootstrap does not provide a template called bootstrap/nav.html, I guess you are using Bootstrap-Flask since the latter has the bootstrap/nav.html template and the render_nav_item macro.
