I need to use rospy for my app, and when i try to install it via pip3 install rospy or pip3 install python-rospy it results an error: ERROR: Could not find a version that satisfies the requirement python-rospy (from versions: none) ERROR: No matching distribution found for python-rospy
I have no idea how to use it and where to download it
Thanks for any responces!
There could be multiple reasons behind these errors. I think you should first check if you have ROS1 installed on your system. Since you're going to use Python3, you'll have to install ROS1 Noetic. You can follow the instructions mentioned on http://wiki.ros.org/noetic/Installation/Ubuntu
If you already have ROS1 Noetic on your system, you should check if you've source ROS1 in your .bashrc. If source /opt/ros/neotic/setup.bash is already there, then something went wrong during the installation. You should install ROS again.
Hope this helps.

You can follow these steps:
Clone the repository:

I'm trying to install a package called pyeto. Their website (https://pyeto.readthedocs.io/en/latest/) does not mention any problems regarding the installation and I can't find any installation related problems of other users. I'm doubting what solution I should look for (I would appreciate it to not have to reinstall python). I'm running python version 3.6.8 and the errors are presented below.
If you have an idea on how to solve this issue please let me know. I'm not an expert on how python runs in the background and how packages are installed through pip. Thanks in advance! B.
ERROR: Could not find a version that satisfies the requirement pyeto (from versions: none)
ERROR: No matching distribution found for pyeto
EDIT: pip --version
pip 20.2.2 from c:\users\user\anaconda3\lib\site-packages\pip (python 3.6)
The author hasn't put it on pypi, so pip is treating it as an unknown package.
See https://github.com/woodcrafty/PyETo/issues/3
Check on the website on what version it is supported.

I was not able to use PYTHON on my computer but you can see the video.
C++: I have solved it by installing Cmake, and later using opencv_master and opencv_contrib_master. You have to install Cmake and add it to the Path directories on windows. Later you will have to add opencv_master to Cmake an configure it, check none error is matched, later you have to add opencv_contrib_master/include to EXTRA_MODULES, you have to choice NONFREE and WORLD option, configure and generate. Thats the most important, you can use the next video. It work for me, just remember to use the instrucctions above.

I'm trying to install django-trumbowyg https://github.com/sandino/django-trumbowyg to my app
When I did pip install django-trumbowyg, it returned this error:
Could not find a version that satisfies the requirement django-trumbowyg (from versions: )
No matching distribution found for django-trumbowyg
Does anyone know what this means? And how I can fix it?
As https://pypi.python.org/pypi/django-trumbowyg#downloads shows, there's only a binary package for Python2 at PyPI.
So, you have to install the package directly from the official sources as pointed out by Rishav in the meantime.
Then ask the developer to upload a source package to PyPI and/or build the wheel as universal.
You may also get this error if your company firewall doesnt allow any package from external source. you might need to add a proxy in that case.
for example: pip install django-trumbowyg --proxy=proxy.companydomain.com:
Python n00b here trying to install decoder.py via pip.
I see it exists when I search for it
$ pip search decoder.py
decoder.py (1.5XB) - Cross-platform Python module for decoding compressed audio files
But i can't seem to install it.
$ pip install decoder.py
Collecting decoder.py
Could not find a version that satisfies the requirement decoder.py (from versions: )
No matching distribution found for decoder.py
$ pip install decoder.py==1.5XB
Collecting decoder.py==1.5XB
Could not find a version that satisfies the requirement decoder.py==1.5XB (from versions: )
No matching distribution found for decoder.py==1.5XB
Any ideas?
This package doesn't provide any downloadable source code on PyPI.
You can download it from http://www.brailleweb.com/cgi-bin/python.py (this link was provided by authors on pypi, proceed with caution).
Author of decoder.py here. :D
I am sorry for inconvenience. pip was able to grab decoder.py from brailleweb.com before. It was unable to install it though because I didn't provide a setup script. I didn't do it primarily because people might like to choose which external decoders they would like to use and perhaps don't want to install them into their's Python site-packages directory on Windows.
So I settled for manual installation instead. You aren't first who complained about it and that's why next version will have the setup script at least.
The new version is coming out soon. I am sorry to say development is slower than I anticipated but new version will be ready sooner or later. :D
Cheers!
