[Solved] Yocto Error: ERROR: Execution of event handler ‘sstate_eventhandler2‘ failed

Bitcake failed on the simplest recipe

1. Compilation error: error: execution of event handler ‘sstate’_ eventhandler2’ failed

Download the yocto code. When compiling, the following errors are reported:

$ bitbake core-image-minimal

It looks like a python error. Who knows what the problem is? Am I using the wrong version?

The following is the output of Python — version

$ python --version
Python 2.7.12

2. How to solve it?

Delete the TMP and sstate cache directories, try again, and compile OK
