Python無法找到我的軟件包：

Question

我已經能夠運行我從IDE寫入瓶中的Web應用程序。它運行良好，當我試圖將它移動到一個新的系統時，它打破了（找不到我在lib文件夾中寫入的文件）。

如何找到我的lib文件？我發現這對瓶：

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

而且我認爲，這將與丟失.tpl文件的幫助，但我怎麼一般這樣做的蟒蛇？我可以在main.py中添加某種python.PATH.insert()嗎？

這裏是我的目錄結構：

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)*

也許你已經忘了放了__init__.py文件在您lib文件夾。 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.
