pydev安装后找不到python库
我正在使用 Django 和 PyDev/Eclipse。我刚刚使用 setup.py install 安装了 django-treebeard，它安装在我的 site-packages 目录 C:\Python26\Lib\site-packages 中。我可以使用 import treebeard 在 python shell 中成功导入它。然而，PyDev 抱怨当我尝试导入它时它无法解决它。
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，但显然它不会。我缺少什么？
谢谢
I'm using Django and PyDev/Eclipse. I just installed django-treebeard with setup.py install and 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.
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?
thanks

Pydev 不会自动重新扫描 site-packages 文件夹。您需要转到
Preferences->;口译员-> Python并单击“应用”使其再次扫描。Pydev doesn't automatically rescan the site-packages folder. You need to go to
Preferences-> Interpreter -> Pythonand click apply to make it scan again.当我安装新包时，我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，它也没有检测到新的软件包。所以最后我单击列出的“单击此处配置未列出的解释器”并删除已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 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.
我发现关闭项目并重新打开（重新扫描解释器后）对我有用。
I've found that closing the project and reopening (after rescanning the interpreter) works for me.
好吧，我按照以下顺序使其工作：
1）我使用 pip install 安装了所需的库
2) 我在 Eclipse 中进入： Window -->偏好设置 -->派德夫 -->口译员 --> Python解释器，然后单击“快速自动配置”。它成功了。
Well, I followed this sequence to make it work:
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.
