如何通知 PyCharm 自定义模块的位置? [英] How do I inform PyCharm of the location of custom modules?

问题描述

我有一个使用以下结构设置的应用程序.

I have an application at work that is set up with the following structure.

/project_root
    /applications
        /app1
            __init__.py
        /app2
            __init__.py
        ...
        /appN
    /pkg
        /database
            __init__.py
        /toolbox
            __init__.py
        ...
        __init__.py
    __init__.py
    main_framework.py

我正在研究使用 PyCharm(社区版)，而不是 Eclipse 的 PyDev 工具.在 app1 的 __init__.py 中，我有一个如下所示的导入语句:

I'm investigating using PyCharm (community edition), instead of Eclipse's PyDev tool. In __init__.py in app1 I have an import statement that looks like this:

import pkg.database

PyCharm 使用 no module named pkg 消息抱怨导入.

PyCharm complains about the import with a no module named pkg message.

不过，由于框架的构建方式，系统运行得很好.每个 appN 都知道 pkg 目录.我如何通知 PyCharm 我在 pkg 目录中有自定义构建的模块，以便这些警告停止?

Due to how the framework is built, though, the system runs just fine. Each of the appNs know about the pkg directory. How do I inform PyCharm that I have custom built modules in the pkg directory so that these warnings stop?

我正在测试 PyCharm 4.0.3 社区版.

I am testing PyCharm 4.0.3 Community Edition.

我尝试了几件事，感谢下面的评论，但没有帮助:

A couple things I've tried, thanks for comments below, that haven't helped:

• 在项目结构"对话框中，project_root 被列为对话框右侧内容根目录"下的唯一目录.我已经添加了 pkg 目录，以便它也被列出.这没有效果.
• 在问题的初始版本中，我在显示结构时错过了 pkg 中的 __init__.py.该文件确实存在.

• In the Project Structure dialog, project_root was listed as the only directory under "Content Root" on the right hand side of the dialog. I've added the pkg directory so that it is listed as well. This had no effect.
• In the initial version of the question, I missed the __init__.py in pkg when displaying the structure. This file does exist.

推荐答案

解决方案是一个两步过程:

The solution to this was a two step process:

1. 添加 pkg 目录作为源根目录.通过选择File -> Settings -> Project ->(选择项目)-> Project Structure然后选择pkg 目录并通过单击Sources 按钮添加.单击确定.
2. 然后选择File -> Invalidate Caches/Restart -> Invalidate and Restart

1. Add the pkg directory as a source root. Do this by selecting File -> Settings -> Project -> (select the project) -> Project Structure then select the pkg directory and add by clicking the Sources button. Click Ok.
2. Then select File -> Invalidate Caches / Restart -> Invalidate and Restart

等待 PyCharm 重新启动并重建它的缓存/扫描索引.现在 pkg 目录被检测为源根目录，我的错误消失了.

Wait for PyCharm to restart and rebuild it's cache / scan the indexes. Now the pkg directory is detected as a source root and my errors are gone.
