That means your cryptography
package is lower than the required version 2.21. So you can use pip
to upgrade your cryptogrpahy.
pip install --upgrade cryptography
But a better approach is to use virtualenv to install and maintain python projects in order to avoid such conflicts.
when i trying to install flowing error appears: Installed /usr/local/lib/python3.5/dist-packages/commandment-0.1-py3.5.egg Processing dependencies for commandment==0.1 error: cryptography 1.2.3 is installed but cryptography>=2.2.1 is required by {'PyOpenSSL'} how to resolve this error?
