Python 找不到我的包 :

Question

我已经能够从 IDE 运行我在 Bottle 中编写的 Web 应用程序。它工作得很好，当我尝试将它移动到新系统时，它坏了(找不到我在 lib 文件夹中编写的文件)。

如何让它找到我的 lib 文件？我找到了这个瓶子:

bottle.TEMPLATE_PATH.insert(0,'/absolut/path/to/templates/')

我认为这将有助于解决丢失的 .tpl 文件，但一般来说我该如何为 python 做到这一点？我可以在 main.py 中添加某种 python.PATH.insert() 吗？

这是我的目录结构:

DEV
├───.idea
│   ├───inspectionProfiles
│   └───scopes
└───myProject *(Also has a .py file I need)*
    ├───output
    │   └───processed
    └───webapp
        ├───src
        │   ├───lib
        │   │   └───*(All my .py files I need)*
        │   ├───static
        │   │   ├───css
        │   │   ├───files
        │   │   ├───img
        │   │   └───js
        │   └───views *(All the .tpl files I need)*
        │       ├───main
        │       ├───popup
        │       └───reports
        └───main.py *(The file that acesses the .py files)*

也许您忘记将 __init__.py 文件放入 lib 文件夹中。 Here's why you need the __init__.py file :

The init.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, init.py can just be an empty file, but it can also execute initialization code for the package or set the all variable, described later.
