No such file or directory: 'mermaid'

[ebsd]

Hi !

I installed mermaid-cli: npm install mermaid.cli I set the variable MERMAID_BIN='~/node_modules/.bin/mmdc' I installed pandoc-mermaid-filter : pip install pandoc-mermaid-filter --user

When I run pandoc, I get : FileNotFoundError: [Errno 2] No such file or directory: 'mermaid'

Can you help me ?

$ pandoc test.md -o test.pdf --filter pandoc-mermaid

Changing this line

mermaid in the following line to mmcd worked for me

MERMAID_BIN = os.path.expanduser(os.environ.get('MERMAID_BIN', 'mermaid'))
