Hi,

Run pip3 install -r requirements.txt

3

It’s perfect thanks a lot

Many thanks.
I had the same issue exactly.

The solution works fine.

Hi, worked also for me while using the ./validate.php script. However, when I check in the librenms GUI, it still says the error is there: Fail: Python3 module issue found: ‘The ‘redis>=3.0’ distribution was not found and is required by the application’

Any hints why the script results different than the GUI in librenms?

Regards
Stefan

I am getting this same error after a fresh install on Ubuntu 18.04 and following the documentation for NGINX install. When running the librenms installation step, I did notice an error about pip3 not being found. I do not see pip3 in the /opt/librenms directory. Is pip3 found somewhere else?

7

apt install python3-pip

8

Thanks! That works. That package is missing from the list of packages to install in the documentation for Ubuntu 18.04 and NGINX.

After fixing pip3 with apt and doing “pip3 install -r requirements.txt” and restarting apache, the error also remains visisble in the validate.php webpage, NOT the CLI validate.php output.

I am getting the same error on a brand new install of Ubuntu 18.04 and LibreNMS. I’ve run pip3 against the requirements.txt, it installs and the error persists:

#:/opt/librenms# su librenms

Thanks for the fix :slight_smile:

I have the same problem, the webinterface complains about missing redis>=3.0 but validate.php shows no error. I restarted both nginx and php7.3-fpm (debian buster).
Also, pip3 install -r requirements.txt confirms it is already installed:

$ pip3 install -r requirements.txt 
Requirement already satisfied: PyMySQL in ./.local/lib/python3.7/site-packages (from -r requirements.txt (line 1)) (0.9.3)
Requirement already satisfied: python-dotenv in ./.local/lib/python3.7/site-packages (from -r requirements.txt (line 2)) (0.13.0)
Requirement already satisfied: redis>=3.0 in ./.local/lib/python3.7/site-packages (from -r requirements.txt (line 3)) (3.5.0)
13

If you install the requirements as root, you won’t get a web error.

However, I have a PR to disable the web check when the web server isn’t running as the poller user. As it could be inaccurate then (as you all have seen).

14

You have to use: sudo -H pip3 install -r requirements.txt
And all will be well in the Web page also.
If you simply do a sudo pip3 install -r requirements.txt it says so.
but it also says that “Requirement already satisfied: …”
And even more confusing if you don’t use “sudo” as a non prived user , it says:
“Successfully installed PyMySQL-0.9.3 python-dotenv-0.13.0 redis-3.5.0”

So try: “sudo -H” as suggested when running sudo without options.

my 2 cents.
