Could not write the graph in DOT format. Please install either `pygraphviz` or `pydot` modules.

cfn-lint version: (cfn-lint --version). cfn-lint 0.37.1

Description of issue.. Attempting to use --build-graph and getting the following error. This is with any template I try.

❯ cfn-lint --build-graph tomcat.yaml 2020-10-26 11:42:06,181 - cfnlint.template - ERROR - Could not write the graph in DOT format. Please install either pygraphviz or pydot modules.

I have verified that dot is available: ❯ which dot /usr/local/bin/dot ❯ dot -V dot - graphviz version 2.44.1 (20200629.0846)

I have graphviz is installed via brew: ❯ brew install graphviz Warning: graphviz 2.44.1 is already installed and up-to-date To reinstall 2.44.1, run brew reinstall graphviz

I have verified path: /Users/joshkonkol/.pyenv/shims:/Library/Frameworks/Python.framework/Versions/3.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/VMware Fusion.app/Contents/Public:/usr/local/go/bin

This was helpful. I did indeed have two versions of cfn-lint. I removed the old version and updated my path and it does indeed work.

Thanks for your help

You will also have to specify a file.

Did you notice that this is different from the output yesterday? I don’t know what you did, but chances are it will work now
