如何在 CPython 上安装 networkx 包

Question

我在我的本地机器上安装了 CPython [1] (macOS Catalina, v. 10.15.4) 来加速 networkx 包中函数 optimize_graph_edit_distance 的计算。之前，我在运行宁 Python3 上的代码，这需要很多时间。但是，当我运行使用 CPython 的代码时（CPython 的别名是 python3），我得到以下错误：

Traceback (most recent call last):
  File "/Users/olha/Desktop/GED_optima.py", line 3, in <module>
    import networkx as nx
ModuleNotFoundError: No module named 'networkx'

我尝试了 python3 -m pip3 install networkx，但出现以下错误：

有人知道如何在 CPython 上安装 networkx 吗？

谢谢！

您可以通过以下方式安装 networkx：

git clone https://github.com/networkx/networkx.git
cd networkx
sudo python setup.py install

~~尝试运行以下命令（从Mayur Deshmukh's answer to ssl not available复制）：~~

python3 -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip
