Hi, I have questions about installation of dot2tex and latex from Sage.

[il-seung Jang]

I want to use dot2tex package because I want to see crystal graph on my computer, Sierra 10.12.6.

I installed Sage 8.0, TexLive 2017, Graphviz...

I know that dot2tex package is not installed in Sage. So, I search for installation of dot2tex and then I know that

In Sage terminal, put

-i dot2tex

But, there is an error: Invalid Syntax... Why?

My second question is 

In Cloud Sage (CoCal), I have latex code about crystal graph, and then it works well.

But, the latex code in my computer with Sage 8.0 does not work with some errors.

I attach latex code files.

Please solve the problems.

Thank you.

What is "sage terminal"?
The way to install a Sage package is similar to starting Sage in terminal:

at the shell prompt, type

sage -i dot2tex
