install pycrypto on python3.6 – CentOS

I am running Centos7 with Python 3.6. I am trying to install pycrypto with the command "pip3 install pycrypto". I also installed the dev tools, so gcc is installed. I am getting the following output.
What am I missing?

    That did not work, but I did find the answer in the article.

    I ran "yum -y install python3-devel" and this fixed my issue. I was then able to install pycrypto.

    I also had the same issue for CentOS.
    However, it turned out I was missing one of the dependencies.

    sudo yum install gcc

sudo yum install gcc-c++

sudo yum install python-devel

sudo pip install pycrypto
