pydev doesn't find python library after installation
提问by Raoul Duke
I'm using Django and PyDev/Eclipse. I just installed django-treebeard with setup.py installand it got installed in my site-packages directory C:\Python26\Lib\site-packages. I can successfully import it in the python shell with import treebeard. However PyDev complains that it cannot resolve it when I try to import it.
我正在使用 Django 和 PyDev/Eclipse。我刚刚安装了 django-treebeardsetup.py install并将它安装在我的 site-packages 目录中C:\Python26\Lib\site-packages。我可以使用import treebeard. 但是 PyDev 抱怨当我尝试导入它时它无法解决它。
Unfortunately I have no experience with PyDev and I assumed that it would automatically pick up everything in the site-packages directory but apparently it does not. What am I missing?
不幸的是，我没有使用 PyDev 的经验，我认为它会自动获取 site-packages 目录中的所有内容，但显然它没有。我错过了什么？
thanks
谢谢

Pydev doesn't automatically rescan the site-packages folder. You need to go to Preferences-> Interpreter -> Pythonand click apply to make it scan again.
Pydev 不会自动重新扫描 site-packages 文件夹。您需要转到Preferences-> Interpreter -> Python并单击应用以使其再次扫描。

I also faced the same error when i had installed a new package.i'm using eclipse Helios. Even after applying and re scanning the folder it was NOT detecting the new packages. So finally i clicked on the "Click here to configure a interpreter not listed" listed and deleted the already selected interpreter and used the autoconfig to add the interpreter again. Finally i was able to resolve the issue.
我在安装新包时也遇到了同样的错误。我正在使用 eclipse Helios。即使在应用并重新扫描文件夹后，它也没有检测到新包。所以最后我点击了列出的“单击此处配置未列出的解释器”并删除了已经选择的解释器并使用自动配置再次添加解释器。最后我能够解决这个问题。

I've found that closing the project and reopening (after rescanning the interpreter) works for me.
我发现关闭项目并重新打开（重新扫描解释器后）对我有用。

Well, I followed this sequence to make it work:
好吧，我按照这个顺序使它工作：
1) I installed the desired library by using pip install 2) I went in Eclipse to: Window --> Preferences --> Pydev --> Interpreters --> Python Interpreter, and clicked "Quick Auto-Config". It made the trick.
1) 我使用 pip install 安装了所需的库 2) 我在 Eclipse 中进入：Window --> Preferences --> Pydev --> Interpreters --> Python Interpreter，然后单击“Quick Auto-Config”。它成功了。
