在虚拟环境中用pip安装的Python包在eclipse中不起作用

Question

我是 pyDev 和 Eclipse 的新手。我正在疯狂地尝试弄清楚如何从 Eclipse 中运行新安装的软件包(这样我就可以在控制台中看到结果)。我确实使用此处找到的指令在 Eclipse 中设置了解释器以指向虚拟环境:http://www.caktusgroup.com/blog/2011/08/31/getting-started-using-python-eclipse/

这就是我所做的。创建虚拟环境并使用 pip 安装新包(pandas)。然后我测试一些代码

from pandas.io.data import DataReader

如果我通过在虚拟环境中调用 python 解释器来测试这一行，则一切正常。但是，如果我在 Eclipse 中运行该行，则会出现错误。

一切都无济于事。以下是我收到的错误:

'module' object has no attribute 'tslib'

要将 virtualenv 添加到 Eclipse PyDev 工作区，请转至 Window 菜单条目并选择首选项，在打开的对话框中转至 PyDev->Iterpreter-Python。

在“库”选项卡中单击“新建文件夹”按钮并添加您的虚拟环境。目录。
