pip install error: mistune has no attribute 'BlockGrammar'

[cyhsu]

I see the pip lib has the version 1.5.3
Since I am new, I tried to install the latest version of the flirimageextractor, but it fails.
The error message like below.

root:/usr/src/app# pip install -U flirimageextractor

i will test this out for you and provide a solution to it
Kindly, provide your system environment details including the python version

[ShogunSkinoski]

Have you ever installed mistune package before ? it looks like you are encountering error because of m2r using wrong mistune version. If so then try to install mistune 0.8.4 or older versions

I have the very same issue.

The mistune I have is 3.0.1

(base) alobo@pop-os:~$ pip install mistune
Requirement already satisfied: mistune in ./.local/lib/python3.9/site-packages (3.0.1)

You suggest going back to 0.8.4, is this not going to be too old? Perhaps other packages would complain.
Anyway, What should I do to go back to mistune 0.8.4 ?

this has been fixed in the new version 1.5.5 and m2r has been moved to extra dependancy
