This is not an issue , i a just posting to remind you that routersploit needs more modules installed than the ones on requirements.txt .
You should add to requirements.txt :
pexpect==4.2.1
mock==2.0.0
If these modules are not installed then the program will run , but when executes run_tests.sh will reveal the missing modules before like it is in this next image .

This two are test requirements, needed for testing and development, since this is not a scope of most user they are excluded from requirements.txt file.
