If you want to install and test the DEVELOP branch without deleting/uninstall your stable version, you can follow one of those procedures.

Create a Python virtual environment

python3 -m venv venv-test-glances

Go inside:

cd venv-test-glances
cd bin

Install some deps

./pip install setuptools

If you are not on Windows operating system:

./pip install shtab

Then install the targeted Glances version (example for Glances 4.3.2.dev4):

./pip install -i https://test.pypi.org/simple/ Glances==4.3.2.dev4

Check the result:

./glances -V
Glances version:	4.3.2_dev04
Glances API version:	4
PsUtil version:		5.8.0
Log file:		/home/nicolargo/.local/share/glances/glances.log

pip install --user virtualenv

On Debian like system:

apt install python-dev 

On Redhat like system:

dnf install python-develop 

Note: on others Linux Operating System please install the statics Python development libraries.

mkdir ~/tmp
cd ~/tmp
git clone -b develop https://github.com/nicolargo/glances.git
cd ~/tmp/glances
git checkout develop

cd ~/tmp/glances
make venv

cd ~/tmp/glances
make test

cd ~/tmp/glances
make run

Run the server (on a first terminal):

cd ~/tmp/glances
make run-server

And the client (on a second terminal):

cd ~/tmp/glances
make run-client

cd ~/tmp/glances
make run-browser

Run the server:

cd ~/tmp/glances
make run-webserver

And the client in your favorite Web browser: http://@IPSERVER:61208

Where @IPSERVER is the IP address or hostname where the Glances server is running (localhost if server and client are ran on the same machine).

First of all, try to run Glances with the -d (Debug) flag on the command line. A glances.log file will be generated with a lot of information (to find the glances.log path, please run 'make show-version').

Then you need a GitHub account (it's free...) to log bug on the Glances' tracker.

Click on this link and enter the following information:

• Glances and PsUtil version (output of make show-version command)
• System configuration: Operating system name and version (output of uname -a and python -V on GNU/Linux)
• Problem description (in English) and optionaly error message displayed by Glances
• A copy/paste of relevant messages in the log file (glances.log)
• A copy/paste of make show-issue

Thanks for your time !
