WTForms
was updated to 2.3.0
with a breaking change. I have tried adjusting other requirements such as werkzeug.1.0.0
but no luck yet. Has anyone found a solution?
Here is the stack strace:

Adding to JBLaf's answer,
HTMLString
was replaced withMarkup
. So usefrom markupsafe import Markup
instead.from wtforms.widgets.core import escape_html
was also replaced byfrom markupsafe import escape
In WTForms
2.3.1
these terms are re-added as aliases and a deprecation warning is shown instead of a breaking change.Looking at your logs, it seems that
WTForms 2.3.0
(released a few hours ago) replacedHTMLString
:https://github.com/wtforms/wtforms/issues/581
Right now,
wtforms_components
(0.10.4) is not yet updated for this change, so you have to stick to an older version ofWTForms
(2.2.1)EDIT : This is corrected by the version
2.3.1
ofWTForms
with aDeprecationWarning
(Thanks to davidism and azmeuk for their quick reaction).So you just have to update to WTForms 2.3.1 .
