Python无法找到我的软件包：

Question

我已经能够运行我从IDE写入瓶中的Web应用程序。它运行良好，当我试图将它移动到一个新的系统时，它打破了（找不到我在lib文件夹中写入的文件）。

如何找到我的lib文件？我发现这对瓶：

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

而且我认为，这将与丢失.tpl文件的帮助，但我怎么一般这样做的蟒蛇？我可以在main.py中添加某种python.PATH.insert()吗？

这里是我的目录结构：

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)*

      processing_cursor = col.queue.find({"status":"processing"}).limit(my_limit) 
      if not processing_cursor.count(): 
       queued_cursor = col.queue.find({"status":"queued"}).limit(my_limit)

       # print col.queue.update({"status":"queued"}, {"$set":{"status":"processing"}}).limit(10) 
        processing_cursor = col.queue.find({"status":"processing"}) 
      if processing_cursor.count(): 
       time.sleep(1)

        new_file_name = ona_sum_tool.run_summary(dt_ona_sum_format(doc['start']), dt_ona_sum_format(doc['end']))

        old_id = doc['_id'] 
        # print old_id 
        doc['_id'] = str(new_file_name) 
        doc['status'] = 'done' 

        insert_result = col.queue.insert(doc) 
        if(insert_result): 
         col.queue.remove({"_id":old_id})

也许你已经忘了放了__init__.py文件在您lib文件夹。 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.
