From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

(Solved) Question about Python-packages (discuss.tchncs.de)

submitted 3 months ago* (last edited 3 months ago) by [email protected] to c/[email protected]

17 comments fedilink hide all child comments

I'm having a fair share of problems with OpenSuse Tumbleweed and python atm.

Coming from Linux Mint and windows.

Installing python-packages with pip was pretty easy.

But I have trouble understanding how to install the following packages on TumbleWeed:

tkCalendar

yaml for Python(311)

When I try to use pip I get prompted to use zypper.

I am stuck at this point. Do I have to use something different than zypper? What is the correct way here?

Help very much appreciated and thank you in advance!

**Thanks everyone for the help! **

I could succesfully create a virtual enviroment in my Visualstudio Code and installed the needed libraries. The next step for me would be to create a executable package.

You will want to use virtualenv, it creates isolated "workspace" so that system (python) packages do not conflict or mix.

OK then I have to read about it.

I am a bit confused because the installation with pip on Linux Mint was no problem and didnt throw any errors. I could use my script in the IDE and from console.

On Tumbleweed it seems to be a lot different. From the first look I have to activate the virt. env

Do I have to do this everytime I start the script via console?

Using pip to install packages outside of venv was always a risk, (newer) pip now has this mechanism to really drive the point home that this can break stuff.

Do I have to do this everytime I start the script via console?

Yes, one way to get rid of this requirement is to package the script as binary/executable package (add pyproject.toml with some sane defaults and with proper [project.scripts]) and then install the project using pipx - pipx install -e path/to/the/project/, the -e flag stands for editable and is nice to have here as you won't have to reinstall everytime you change the script.
What pipx does is that it creates the local virtualenv, installs everything the package declares as needed and adds a special executable script into location like ~/.local/bin/ that first sources the venv and then starts the entry script - keeping everything isolated.

Holy shit!

**Thank you very much! **

You did help me big time.

I'm understanding more and was successfull in installing tkcalendar and pyyaml in a virual Enviroment in VisualStudioCode. For now I can use my script.
