I have a similar (?) issue trying to import the package in a fresh pipenv (from PyPI):

>>> import holoviews

Thanks you two!

@BrandonSLockey Could you report panel and holoviews versions?

@MichaelGiazi How did you install holoviews? Can you install jinja2?

[MichaelGiazi]

@philippjfr

Yes, it was jinja2, this fails:

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[packages]
jinja2 = "==3.1.0"
holoviews = "==1.14.8"

but using jinja2 = "==3.0.2" worked correctly. Jinja2 was updated yesterday evening turns out.

[wimiko]

from the Jinja2 3.1.0 releasenotes:

Markup and escape should be imported from MarkupSafe.

Seems that markup is not provided by jinja2 anymore and should be imported from markupsafe:

from markupsafe import Markup

[philippjfr]

Fixed in holoviz/panel#3258. There's now also a 0.13.0a46 dev release available with the fix. Hope to have a real release out very soon.

[philippjfr]

Panel 0.12.7 is now available on PyPI and from the conda pyviz and conda-forge channels.
