Python version problem? requests_async import error

Installation
1

Hello, I don’t know, maybe it’s a python problem?

    File "/srv/homeassistant/lib/python3.7/site-packages/envoy_reader/envoy_reader.py", line 8, in <module>
    import requests_async as requests
ModuleNotFoundError: No module named 'requests_async'

I’m trying to use an updated version of a component (envoy_reader) which uses requests-async (this fails: import requests_async as requests) I did have 0.93.1, and I upgraded to 0.94.1 homeassistant. still same issue.

I ran pip3 install requests-async and I think it installed? but I can’t find a requests-async file, and I still get the import error.
$ pip3 install re
quests-async

Were you in the hassbian venv when you installed requests-async?

Thanks @nickrout !

What do you mean by being ‘in’ the venv? the venv is /srv/homeassistant directory? There’s more to it than that I think.

I did some searching, this post and this post helped with understanding the venv.

I did the following, and it gets past the import error now, and I see requests_async in the ha site packages directory.

homeassistant@hassbian:~ $ source /srv/homeassistant/bin/activate
(homeassistant) homeassistant@hassbian:~ $ which python
/srv/homeassistant/bin/python
(homeassistant) homeassistant@hassbian:~ $ ha hah!!! 
ha hahwhich python! 
bash: ha: command not found
(homeassistant) homeassistant@hassbian:~ $ pip3 install requests-async

Yes, it did install and work, once the package was installed into ha’s venv.
