Error after installation of allure pytest adaptor

问题

I am trying to configure Allure (2.6.0) with Pytest (3.6xx) on a Windows 8 box. I am able to run pytest and generate jUnit xml report file which later I can pass to allure (allure server jUnitXmlFile.xml) and it works fine.

What I need is the additional functionality that Allure provides (metadata,attachments, etc), so I downloaded pytest-allure-adaptor.

So I have the following packages installed in my venv:

allure-pytest==2.4.1
allure-python-commons==2.4.1
pytest-allure-adaptor==1.7.10
...

If I now run py.test.exe, I get the following error:

(venv) c:\TestAutomation>py.test.exe

Is there something wrong with the pytest-allure-adaptor ? Anyone have similar problems?

回答1:

allure-python-commons is incompatible with pytest-allure-adaptor. You need to remove old plugin and reinstall allure-pytest and allure-python-commons.

回答2:

Your pytest-allure-adaptor is incompatible. Only thing is required to run this pip command if you have python2-

pip uninstall pytest-allure-adaptor

else run this command if you have python3 -

pip3 uninstall pytest-allure-adaptor
