Question

由于某种原因，我无法导入networkx。这是我尝试在交互模式下在Python中导入时得到的错误。

>>> import networkx

我在Win7上运行Anaconda，并且还重新安装了networkx。现在运行networkx-2.1。再一次，昨天工作得很好。

我尝试通过conda卸载并重新安装networkx，但它没有帮助。

Answer 1

我通过networkx和conda卸载pip来解决此问题。我必须使用这两种方法安装networkx并最终破坏了一些东西。

步骤：

conda uninstall networkx
pip uninstall networkx
conda install -c anaconda networkx

导入networkx

时，我不会再出错

导入Networkx包时出错
