Troubleshooting installation problems
It can happen that you run into trouble while installing Open Peer Power. This page is here to help you solve the most common problems.
pip3: command not found
This utility should have been installed as part of the Python installation. Check if Python is installed by running python3 --version
. If it is not installed, download it here.
If you are able to successfully run python3 --version
but not pip3
, install Open Peer Power by running the following command instead:
python3 -m pip install openpeerpower
On a Debian system, you can also install python3 by sudo apt-get install python3
, and pip3 by sudo apt-get install python3-pip
.
No module named pip
Pip should come bundled with the latest Python 3 but is omitted by some distributions. If you are unable to run python3 -m pip --version
you can install pip
by downloading the installer and running it with Python 3:
python3 get-pip.py
libyaml is not found or a compiler error
On a Debian system, install the Python 3 YAML library by sudo apt-get install python3-yaml
.
distutils.errors.DistutilsOptionError: must supply either home or prefix/exec-prefix – not both
This is a known issue if you’re on a Mac using Homebrew to install Python. Please follow these instructions to resolve it.
No access to the frontend
In newer Linux distributions (at least Fedora > 22/CentOS 7) the access to a host is very limited. This means that you can’t access the Open Peer Power frontend that is running on a host outside of the host machine. Windows and macOS machines may also have issues with this.
To fix this you will need to open your machine’s firewall for TCP traffic to port 8123. The method for doing this will vary depending on your operating system and the firewall you have installed. Below are some suggestions to try. Google is your friend here.
For systems with firewalld (Fedora, CentOS/RHEL, etc.):
sudo firewall-cmd --permanent --add-port=8123/tcp
sudo firewall-cmd --reload
For UFW systems (Ubuntu, Debian, Raspbian, etc.):
sudo ufw allow 8123/tcp
For iptables
systems (was the default for older distributions):
iptables -I INPUT -p tcp --dport 8123 -j ACCEPT
iptables-save > /etc/network/iptables.rules # your rules may be saved elsewhere
After upgrading, your browser login gets stuck at the “loading data” step
After upgrading to a new version, you may notice your browser gets stuck at the “loading data” login screen. Close the window/tab and go into your browser settings and delete all the cookies for your URL. You can then log back in and it should work.

Not initializing discovery because could not install dependency netdisco
If you see Not initializing discovery because could not install dependency netdisco==x.y.z
in the logs, you will need to install the python3-dev
or python3-devel
package on your system manually (eg. sudo apt-get install python3-dev
or sudo dnf -y install python3-devel
). On the next restart of Open Peer Power, discovery should work. If you still get an error, check if you have a compiler (gcc
) available on your system.
