You need to be able to build Python extensions written in C. In addition to the compiler, you must also have the Python development headers installed. If you're using a version of Python installed from your operating system's package installer, sometimes that means you must also install a separate package such as "python-dev" or something. For example, on one Fedora system, that meant you needed to "yum install python3-devel". I don't know what it is on your system, you'll have to look.

Good luck!

Reading state information... Done
python3-dev is already the newest version (3.6.7-1~18.04).I have installed Thanks anyway

sudo apt install python-gevent
Fix the issue
