![]() ![]() For example: The system default python: python -m pip install fish A virtualenvs python. This is the recommendation because it works across all versions of Python, and in all forms of virtualenv. ~/.platformio/penv/bin/python -version should give you a 3.x version and using the “portable” interpreter in VSCode should also give the same version – if the option has “stuck”. Most distributions of Linux have Python installed by default, and you can setup multiple virtual environments on Linux (all that a Python VE is a new. The current recommendation is to use python -m pip, where python is the version of Python you would like to use. Now, in order to use the new installed Python distribution you have to: cleanup you PATH and LDLIBRARYPATH: Remove all old Python paths and. If you are a Fedora user, you might want to read about multiple Python versions. All the Python developers are recommended to use a virtual environment for the applications. Once you have installed multiple Python versions, you can switch the default Python with the update-alternatives tool. There are three pythons there, python, python3 and python3x - they are symlinks to either the system wide python3 interpreter, or, to the downloaded python3 interpreter as appropriate. Using the prefix scheme, you can for example install Python 2.7 into the folder /opt/py27. For example installing the python3.9 package on Fedora 32 to get Python 3.9. You can install more than one Python version on a single system. “Use a portable python 3 interpreter if available” – if you tick/check that, it will use the python 3 interpreter that it downloaded into ~/.platformio/penv/bin. tar.gz approach because the server I will be installing on wont have access to the net, so I will have to ftp the files over then install. Does it really make a difference which python. There’s a PlatformIO option to use a portable python interpreter: Well the instructions I found for installing multiple pythons on the same machine mentioned building the files your self. If you got 3.x, open the PlatformIO terminal next, left side, click ant/alien head icon, look for an option to open a terminal.Įxecute python -version again. ![]() What do you get if you open a terminal inside VSCode (from the menubar) and type python -version? I would expect the one you configured. In short: I'm currently using python 2,6, but I'd like it to change to 2.4 for all the modules as that's what I'm going to be using.Right then, It should be using it if you have configured it. It can install multiple Python versions, specify the version. The blogs/answers I've found say to use easy_install, but that doesn't support the packages I need (Or at least, it just died when I tried). Install Pyenv: Pyenv is a program thats used for Python version management on macOS and Linux. How would I go about getting these modules to work for Python2.4? I've tried reinstalling (With 2.4 as my primary), but that just caused errors. Then activate the testenv by running the following command on Windows PowerShell: >. Run the following command: > py -3.7 -m venv testenv. (I develop on the 2.6 machine, and build on the EeePC). And you want to create a new virtual environment for python 3.7 on a testenv directory. ![]() When we want to swap back to Python 3, we just need to set the global to be system. Example with py the python launcher: py -3.3 -m venv myvenv will create a virtual environment using python 3.3. Instead of providing an argument, like with virtualenv, you just be sure to use the appropriate python version to run venv. The only way out of it is to use venv, a Python Virtual Environment. We can now install dependencies as needed for whatever tools we are using. Its still possible to use a different python version with venv. Until now, I've been using an EeePC (Same device as the ones I'm supporting) to do builds and releases, which has worked well. Running multiple Python versions can be anything between a big mess and a plain nightmare. The problem here, is that I have a lot of devices (Let's say over a thousand) all running 2.4.4, which will soon need to be supported by this machine (For builds of code, releases etc). If I try to import wx on Python2.4, I get the expected no module error. I have Python2.6.5 and Python2.4.4 on my linux machine.Īt the moment, all the modules I have (wx, ply, pyserial, twisted, to name a few) are installed for the 2.6 version of python. ![]()
