Unable to render template

[fendy-myeatclub]

When running mjml-python I get this error that I do not get compared to running : ./node_modules/.bin/mjml index.mjml input.mjml -o output.html

Value Example:

<mjml>
    <mj-head>
        <mj-title>Your order has been cancelled!</mj-title>
        <mj-attributes>
            <mj-all padding="0px"></mj-all>

            <mj-table font-family="Roboto, Helvetica, sans-serif" font-size="14px"></mj-table>
            <mj-section background-color="#ffffff"></mj-section>
            <mj-wrapper background-color="#ffffff"></mj-wrapper>
        </mj-attributes>
        
<mj-style inline="inline">

    .delimited {

    }

    .delimited > td {

    .extra-info {

    }

    .total {

            </mj-column>
        </mj-section>
    </mj-body>
</mjml>

If I pass the string directly I get:

Traceback (most recent call last):
  File "lib/python3.9/site-packages/mjml/mjml2html.py", line 79, in mjml_to_html
    mjBody = mjml_root('mj-body')[0]
TypeError: 'NoneType' object is not callable

If I save the value to a file then I get:

    results = mjml_to_html(rendered_html)
  File "lib/python3.9/site-packages/mjml/mjml2html.py", line 230, in mjml_to_html
    raise ImportError('CSS inlining is an optional feature. Run `pip install -e ".[css_inlining]"` to install the required dependencies.') # noqa: E501
ImportError: CSS inlining is an optional feature. Run `pip install -e ".[css_inlining]"` to install the required dependencies.

When I run pip install, I get:

ERROR: Could not find a version that satisfies the requirement css_inlining (from versions: none)
ERROR: No matching distribution found for css_inlining

Again, I don't get this error when using node.

I have to say that it works for me, even with Python 3.9 (using Fedora Linux here). Which operating system are using?

Could you try creating a fresh virtualenv and installing the latest version of mjml? And last but not least you could try relaxing the css_inline requirement and install the latest version.

I can not reproduce the problem locally. Feel free if you can reproduce the problem with the latest version of mjml.
