Looks like you have an error in the source document and the extension isn't handling failures properly. Please can you post your diagram source so I can recreate it.

rpinku commented 5 years ago

I found the cause, it happens because I use the markdown preview extension for which I need to put the mermaid code inside

.........

to resolve this I now add %% before these two lines when I want to export

Gruntfuggly commented 5 years ago

Please could you post an example? It would be good to add to the README.md.

rpinku commented 5 years ago

This will show well when using the VSC plaugin Markdown Preview mermaid Support

graph TB
    A-->B
    A-->C
    B-->D

But if you wish to export it to an image you need to add %% otherwise the export will fail to parse %%mermaid graph TB A-->B A-->C B-->D %%

Gruntfuggly commented 5 years ago

I'm slightly confused - is the mermaid snippet embedded in a markdown document?

same code can be evaluated in mermaid live editor

code here :

      A(A) -- X --> B
      B -- Y --> C(C)
      B -- Z --> D(D)

Note: Below, I'm using the character ' to represent ` due to formatting issue on github.

I had the same issue when I tried to export a mermaid code embedded in a markdown .md file containing the following content.

Filename: example.md

'''mermaid
graph TD;
    A((0));
    B((1));
    A-->B;
'''

The "fix" I found is, do not give your filename a .md extension and do not embed it in the

'''mermaid '''

block; i.e. just use a plain file without or any file extension other than .md, and use raw mermaid code, e.g.

Filename: example.txt

graph TD;
    A((0));
    B((1));
    A-->B;

The export should now be successful.

p.s. I also had to install Node.js first and execute

npm install ~/.vscode/extensions/gruntfuggly.mermaid-export-0.0.8/node_modules/mermaid.cli node ~/.vscode/extensions/gruntfuggly.mermaid-export-0.0.8/node_modules/puppeteer/install.js
