Python全路径导入无法在包树中的各个分支上正常工作 [英] Python full path import not working across branches in package tree

问题描述

我具有以下项目结构:

Project
  - GUI
    - ...Modules
  - Data
    - Database
      - ...Modules
    - Files
      - ...Modules
  - Utilities
    - ...Modules

我正在尝试在包装边界上进行一些导入，例如:

And I am trying to do some imports over package borders, for example:

我尝试导入Project.Utilities.Conversions.如果我使用像import Project.Utilities.Conversions这样的完全指定的导入，则此操作将失败，它将与import Utilities.Conversions一起使用，即，我不能指定比其他部分更多的路径.但是，我想使用完全指定的路径，一个原因是eclipse中的pydev更喜欢它们(否则，它向我显示一个错误)，第二个原因是我发现这样做令人困惑.

in the file(Module) Project.Database.dbdriver I try to import Project.Utilities.Conversions. If I use a fully specified import like import Project.Utilities.Conversions this fails, it works with import Utilities.Conversions, i.e. I can not specify more off the path than those part that differ. However I would like to use fully specified paths, one reason beeing that pydev in eclipse likes them better (otherwise it shows me an error), the second reason is I find it confusing not to do so.

我偶然发现了这个问题，但是认为它是错误的/不需要这里

I have stumbled over this but think it is wrong/not needed here How do I create a namespace package in Python?

问题:当在包装结构中交叉子支路时，如何使用完全指定的包含物?

Question: how can I use fully specified includes when crossing subbranches in a package structure?

推荐答案

由于python(或jython)的当前工作目录设置为Project，因此完全指定的导入失败.您可以:

The fully specified import failed because the current working directory of python(or jython) was set to Project. you can:

将Project的父目录添加到您的python lib

add the parent directory of Project to your python lib

import sys
sys.path.append('/parent/of/project')

或者只是在调试设置中将jython的工作目录更改为Project的父目录.(我不知道如何做，因为我不使用pydev.)

or just change the working directory of jython to the parent of Project in the debug settings.(I don't know how to do it because I don't use pydev.)
