Hello,

I found this issue while installing.

Getting requirements to build wheel ... error ERROR: Command errored out with exit status 1: command: 'c:\python27\python.exe' 'c:\python27\lib\site-packages\pip_vendor\pep517_in_process.py' get_requires_for_build_wheel 'c:\users\teammy\appdata\local\te mp\tmpqqqvvh' cwd: c:\users\teammy\appdata\local\temp\pip-install-1bimly\opencv-python Complete output (22 lines): Traceback (most recent call last): File "c:\python27\lib\site-packages\pip_vendor\pep517_in_process.py", line 280, in main() File "c:\python27\lib\site-packages\pip_vendor\pep517_in_process.py", line 263, in main json_out['return_val'] = hook(**hook_input['kwargs']) File "c:\python27\lib\site-packages\pip_vendor\pep517_in_process.py", line 114, in get_requires_for_build_wheel return hook(config_settings) File "c:\users\teammy\appdata\local\temp\pip-build-env-llenxw\overlay\Lib\site-packages\setuptools\build_meta.py", line 146, in get_requires_for_build_wheel return self._get_build_requires(config_settings, requirements=['wheel']) File "c:\users\teammy\appdata\local\temp\pip-build-env-llenxw\overlay\Lib\site-packages\setuptools\build_meta.py", line 127, in _get_build_requires self.run_setup() File "c:\users\teammy\appdata\local\temp\pip-build-env-llenxw\overlay\Lib\site-packages\setuptools\build_meta.py", line 243, in run_setup self).run_setup(setup_script=setup_script) File "c:\users\teammy\appdata\local\temp\pip-build-env-llenxw\overlay\Lib\site-packages\setuptools\build_meta.py", line 142, in run_setup exec(compile(code, file, 'exec'), locals()) File "setup.py", line 448, in main() File "setup.py", line 99, in main % {"ext": re.escape(sysconfig.get_config_var("EXT_SUFFIX"))} File "c:\python27\lib\re.py", line 210, in escape s = list(pattern) TypeError: 'NoneType' object is not iterable

I ran the script and found the issue below that causes 'No keyword found'. I'm not sure it relates to the above issue or not. Any suggestion to resolve this case?

[ ERROR ] Error in file 'D:\automate\RF\RF-Scripts\POC\tests\PruCnt-Login-ValidID.robot' on line 4: Importing test library 'ScreenCapLibrary' failed: ImportError: No module named ScreenCapLibrary Traceback (most recent call last): None PYTHONPATH: C:\Python27\Scripts\robot.exe C:\WINDOWS\SYSTEM32\python27.zip c:\python27\DLLs c:\python27\lib c:\python27\lib\plat-win c:\python27\lib\lib-tk c:\python27 c:\python27\lib\site-packages

Thank you in advance

Could be because opencv-python no longer supports Python 2.7. You could try installing an older version: pip install opencv-python==4.2.0.32 and try again.

Thank you for reply. I change python version to 3.5 and install open

Thank you for your suggestion. I change python version to 3.5 with recommended opencv-python. I still got this issue when I run a script

Do you still have this issue when trying to install latest version @kattinum?

On Windows, also the installation of opencv-contrib-python is needed.
