从 pydev 中的另一个项目导入 [英] Importing from another project in pydev

问题描述

我一直在四处寻找，但我找不到答案.类似的问题与第三方库的一些棘手案例有关，但我的情况似乎很简单.尽管如此，我还是无法弄清楚这是如何工作的.

I've been looking around for quite some time but I just can't find the answer. Similar questions relate to some tricky cases with third party libraries and all, but my situation seems to be textbook-simple. Nevertheless I can't figure out how this works.

我使用的是 Eclipse 3.5.2、Pydev 2.2.0，在 Ubuntu 11.04 机器上运行.

I'm using Eclipse 3.5.2, Pydev 2.2.0, running on an Ubuntu 11.04 machine.

我的情况看起来很简单:我想写一个包作为自己的项目，然后我想在另一个项目中使用这个包编写一个应用程序.

My case seems simple: I want to write a package as its own project, and then I want to write an application using this package in another project.

我应该如何设置 pydev 以便我可以拥有这两个项目core"(包)和app"(使用核心包)，并从app"内部执行:

How should I setup pydev so that I can have this two projects "core" (the package) and "app" (which uses the core package), and from within "app" do:

import core

?

• 我已将核心添加到应用程序的项目参考中，但它没有做任何东西.
• 我已将/core/添加到源文件夹中(我不得不强制这样做，因为它不是显示在列表中)，它不起作用(所以我删除了它).
• 我已将/full/path/to/core 添加到外部库，但它仍然不起作用.

不起作用"是指我总是收到未解析的导入:核心".

By "doesn't work", I mean that I get an "unresolved import: core", always.

想法?

推荐答案

如果您有 2 个项目并正确设置了 PYTHONPATH(通过源文件夹)，它应该只需添加一个项目引用即可.

Provided you have 2 projects with the PYTHONPATH properly set (through source folders), it should work just adding a project reference.

也许一个例子可以帮助...

Maybe an example can help...

例如:

project1
project1/src <-- this should be set as the source folder
project1/src/core
project1/src/core/__init__.py

project2
project2/src <-- this should be set as the source folder
project2/src/app
project2/src/app/__init__.py

然后编辑 project2 属性 > 项目引用并选择project1"，以便能够从 project2 访问 project1.

and then edit the project2 properties > project references and select 'project1' to be able to access the project1 from the project2.
