如何使用conda安装pydotplus

Question

I execute the code following on my machine( Win10, python 2.7, Anaconda&Spyder) and meet ImportError: No module named pydotplus .

import networkx as nx
from networkx.drawing.nx_pydot import write_dot
G = nx.DiGraph([(1,2),(2,3),(3,2)])
write_dot(G,'file.dot')

It clearly that I should install pydotplus package. I try to conda install pydotplus directly but says Error: Package missing in current win-64 channels . Then, I google it but find there is no information about how to install it on conda. By the way, I have install pydot on conda before.

Thanks for you help in advance!

Answer 1

• Using conda install command below worked for me (globally installed):

conda install -c conda-forge pydotplus

• Using Anaconda environments (per environment instance) you can install pydotplus using pip :

pip install pydotplus

I would personally recommend using the Anaconda environments to install your packages for a given solution as its a more modular and cleaner way of building solutions with Anaconda.

Installing via Anaconda environments referenced from answer on Quora , see: https://www.quora.com/How-do-I-install-Python-packages-in-Anaconda

Answer 2

I tried conda install pydotplus , but it failed.

Then tried python -m pip install pydotplus and it worked.

Answer 3

Try

pip install pydotplus

if it isn't part of the conda universe.

Answer 4

打开Anaconda提示：

pip install pydotplus
