The – externally-managed-environment – in Python
To avoid this message which is to force you somehow to create a virtual environment in python:
$ pip install .
error: externally-managed-environment
× This environment is externally managed
??> To install Python packages system-wide, try 'pacman -S
python-xyz', where xyz is the package you are trying to
install.
If you wish to install a non-Arch-packaged Python package,
create a virtual environment using 'python -m venv path/to/venv'.
Then use path/to/venv/bin/python and path/to/venv/bin/pip.
If you wish to install a non-Arch packaged Python application,
it may be easiest to use 'pipx install xyz', which will manage a
virtual environment for you. Make sure you have python-pipx
installed via pacman.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.Just remove this in Linux:
sudo rm /usr/lib/python3.11/EXTERNALLY-MANAGEDIf you are using Homebrew just go to:
cd /home/linuxbrew/.linuxbrew/Cellar/python@3.12/3.12.2_1/lib/python3.12and remove the file EXTERNALLY-MANAGED as well.
If on the other side, prefer to create a virtual environment, this is the way, install this package:
python3-venvIn the environment you prefer to work with, use this command:
python3 -m venv .venvYou can check all the installed packaged here:
user@server# ls .venv/
bin include lib lib64 pyvenv.cfgThen you have to activate the environment:
source .venv/bin/activateThen it’s possible to use pip to install packages in that environment:
pip install -r requirements.txtpip install openaiThat’s it.
To deactivate the environment:
deactivateInstalling Apache2 on Arch Linux
Free and open source Apache is one of the most popular servers in the world.
It is based on a focused architecture and supports all major operating systems, Linux, Windows, macOS and Solaris.
Apache is customizable and can be integrated with other, It offers many features, including load balancing , URL tracking, automatic indexing , robust support, and more.
I’ll make it simple:
Let’s do the update:
sudo pacman -SyuOn Debian is very simple:
sudo apt-get install apache2On Arch Linux:
pacman -S apacheThen we can create the symbolic link, to boot apache on the start.
and we use these commands:
systemctl start httpd
systemctl enable httpd
We can check the status:
systemctl status httpdApache. You can create it in the Apache default root directory using the following command:
nano /srv/http/index.html
Let’s just add some html code in a file:
