python - 导入 Networkx 包时出错

Question

由于某种原因，我无法导入 networkx。这是当我尝试以交互模式在 Python 中导入时出现的错误。

>>> import networkx

我在 Win7 上运行 Anaconda，并且还重新安装了 networkx。现在正在运行networkx-2.1。再说一次，昨天工作得很好。

我尝试通过 conda 卸载并重新安装 networkx，但没有帮助。

Answer 1

我通过 conda 和 pip 卸载 networkx 解决了这个问题。我一定是使用这两种方法安装了 networkx，但最终还是出现了问题。

步骤:

• conda 卸载网络x
• pip卸载networkx
• conda install -c anaconda networkx

导入 networkx 时不再出现错误
