📢 A quick PSA here in case anyone is having trouble installing Meltano: We have become aware of an install issue which began yesterday evening. This issue appears to be caused by a version bump in one or our dependent libraries related to

flask

and

markupsafe

. You can follow our progress on this issue and post comments in the issue if you are affected. Current ETA is 5pm Central time or sooner, expecting resolution in our new Meltano release already planned to come out later today. Error ImportError: cannot import name 'soft_unicode' from 'markupsafe' (#3257) · Issues · Meltano / Meltano · GitLab

For anyone installing Meltano before a fix is released, you can fix this issue by constraining dependencies for the

pip install

. For the latest version, you can run:

echo "MarkupSafe==2.0.1" >> constraints.txt
pip install -c constraints.txt meltano

For

meltano==1.84.0

(which we are using),

wtforms

has to be constrained as well:

echo "wtforms<3.0.0" >> constraints.txt
echo "MarkupSafe==2.0.1" >> constraints.txt
pip install -c constraints.txt meltano==1.84.0

As @edgar_ramirez_mondragon notes in the below thread, it seems

dbt

users are similarly affected and they (dbt Labs) have their own issue tracker as well for the impact on dbt: https://meltano.slack.com/archives/CKHP6G5V4/p1645211420572649
