No matching distribution found for cv-bridge python
You have to actually install CV_Bridge and your script is failing because it cannot find a match for the exact version. As mentioned in the comment, this is almost certainly because of how old that version is. You should install the bridge via apt by doing sudo apt-get install ros-(DISTRO)-cv-bridge and sudo apt-get install ros-(DISTRO)-vision-opencv.
I have a script in python that uses cv-bridge. But I keep getting this error:
ERROR: Could not find a version that satisfies the requirement cv-bridge==1.15.0 (from -r requirements.txt (line 5)) (from versions: none)
ERROR: No matching distribution found for cv-bridge==1.15.0 (from -r requirements.txt (line 5))
To reproduce the error:
pip install -r requirements.txt
requirements.txt:
cv-bridge==1.15.0
Does anybody know how to solve it?
