Today, Suddenly my robot Runner.py was not working. Basically Runner.py contains the command line commands to run my robot testcases based on the tags. Evreytime when the Runner.py is ran, a requirements.txt file will be executed and all the libraries in it will be installed by python intepreter.
cmd="pip install -r Requirements.txt --trusted-host files.pythonhosted.org --user"
os.system(cmd)
And then the testcases are ran by python intepreter using:
cmd="robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
os.system(cmd)
And reports are generated using:
cmd="python3 -m robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
os.system(cmd)
Where RunNow is the tag i am using in my testcases and TestSuite is my Folder which contains my .robot test files.
Till Yesterday all this commands were working perfectly, but today it was not working, the first error I got is

Then I tried pip freeze > file.txt to get all the libraries installed, uninstalled all of them through the command
cmd="pip uninstall -r file.txt"
os.system(cmd)
As I ran the runner.py file in the command prompt, it first uninstalled all the libraries in file.txt and installed all the libraries in Requirements.txt and ended up saying
robot is not recognized as internal or external command robotframework, robotmetrics is not recognized as internal or external command robotframework
So after some research I replaced
cmd="robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
to
cmd="python3 -m robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
and
cmd="robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
to
cmd="python3 -m robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
Now after making this changes I am not getting robot or robotmetrics is not recognized as internal or external command robotframework but **My Testcases are not picked up with respect to tags, actually it simply executes the command for installing all libraries in Requirements.txt and stops.
After running Runner.py my command prompt looks like:

Please Help on this...
It is not easy to understand what is going on. When you say:
Till Yesterday all this commands were working perfectly, but today it was not working, the first error I got is
unexpected error: valueerror: not enough values to unpack (expected 3, got 1) robot
The first thing you need is to identify where that error is coming from. Maybe the omitted lines before the error, could help to do that.
One problem I see in this (strange) way to install and run robot, is the fact that you do not set specific versions for the packages. If a new version of a package causes and error, then you may be in the current situation.
