Python无法找到我的包：

Question

I have been able to run a web app I wrote in bottle from my IDE. It works well, and when I tried to move it to a new system, it broke (couldn't find the files I wrote in the lib folder).

How do I get it to find my lib files? I found this for bottle:

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

And I think that will help with the missing .tpl files, but how do I do this for python in general? Can I add some sort of python.PATH.insert() to my main.py?

Here is my dir structure:

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)*

Perhaps you have forgotten to put the the __init__.py file in your lib folder. 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.
