Unable to activate Minemeld MISP Extension

[ct12388]

Clicked activate and encountered errors. Logs reflects pyrsistent requires Python '>=3.5' but the running Python is 2.7.12
Tried to manually configure MISP prototype, but unable to commit, says class mmmisp.Miner in MISP_anyEvent

• Minemeld` Version is the latest, installed on ubuntu 16
• MISP version is 2.4.136

I induced MineMeld to install a Python 2.7-friendly version of pyrsistent by:

1. Installing the extension
2. Modifying the extension's requirements.txt file so that it installs the desired package before it installs pymisp (which has pyrsistent>=0.14.0 in its requirements)

/opt/minemeld/local/library/<EXTENSION_GUID>/requirements.txt

minemeld-core>=0.9.37b1
pyrsistent==0.16.1
pymisp==2.4.96

3. Activating the extension in the MineMeld UI
