pip installs version 0.0.0 of the package MarkupSafe

Question

I'm trying to install MarkupSafe for python 3.5 on Ubuntu 16.04 Running in Docker. Running pip3 install markupsafe==2.0.1 gives

Installing collected packages: markupsafe
Successfully installed markupsafe-0.0.0

I tried reinstalling, I tried pip3 install with -U, I still get version 0.0.0. Running pip3 show -f markupsafe gives

You are using pip version 8.1.1, however version 21.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

so I can see the __init__.py and the rest of the py files are missing. This is the only package that causes a problem. Running pip3 list -l gives:

...
distro (1.5.0)
fasteners (0.16)
future (0.18.2)
idna (2.10)
Jinja2 (2.11.3)

node-semver (0.6.1)

pluginbase (1.0.1)

(without the <----)

Answer 1

MarkupSafe 1.1.1 works with Python 2.7 and 3.4+ so install it with

pip3 install "markupsafe==1.1.1"

or

pip3 install "markupsafe<2.0"
