Fix Peertube youtube-dl not Downloading

Posted on by

Issue was not being able to import a video into Peertube using a URL.

Peertube was set up to use youtube-dl which is in /var/www/peertube/storage/bin/youtube-dl. Further investigation showed that Peertube calls it with python.

For example 

python youtube-dl video-to-download

Usually Python refers to Python 2 where as Python3 refers to Python 3.

We can create a symlink so that python = python3

sudo ln -s /usr/bin/python3 /usr/bin/python

This way when Peertube runs python, it technically will run it with python3.

Note you will probably run into issues if you do have Python 2 installed and need it. In my case, python was not installed and didn’t reference anything.

The Problem

Running the ./validate.php script returns the following error

[FAIL]  Python3 module issue found: 'Required packages: ['PyMySQL!=1.0.0', 'python-dotenv', 'redis>=3.0', 'setuptools', 'psutil>=5.6.0', 'command_runner>=1.3.0']
Package not found: The 'command_runner>=1.3.0' distribution was not found and is required by the application
'
        [FIX]:
        pip3 install -r /opt/librenms/requirements.txt

Running the [FIX] throws an error saying gcc failed with exit status 1.

The Solution

Fortunately this issue is easy to resolve.

First we need to install python3-devel

sudo yum install python3-devel

Next, as the librenms user, run the pip command to install the requirements.

pip3 install --user -U -r /opt/librenms/requirements.txt

Run ./validate.php to verify that everything is working.
