When I install the cert-issuer with  
python setup.py install  
I get an error saying  
Installed /Library/Python/2.7/site-packages/cert\_issuer-2.0.11-py2.7.egg  
Processing dependencies for cert-issuer==2.0.11  
error: pysha3 1.0.2 is installed but pysha3==1.0b1 is required by set([‘merkletools’])

I found this post [https://xiaoxing.us/2018/01/31/Utilizing-BlockCert-Blockchain-Based-Educational-Certificates/](https://xiaoxing.us/2018/01/31/Utilizing-BlockCert-Blockchain-Based-Educational-Certificates/)

I dont know how to makes this operation  
The folder after “Installed” is what we need. Then enter “merkletools-1.0.2-py3.6.egg” folder, edit the METADATA and replace “pysha3 (==1.0b1)” to pysha3 (\>=1.0b1) then save. You need to do the same thing on metadata.json file.  
Can anyone help me?
