Packages of python

Hello everyone,
My openwrt firmware runs on raspberry pi model B. When I install some packages relate to python. I met the error on the below picture. How to fix this problem.
Thanks in advance!!!!!

Can’t read your screenshot, but typically you can only install “pure Python” packages as there is no compiler and needed build tools installed on OpenWrt. Compiled Python packages generally need to be cross-compiled with the OpenWrt build system on another host and installed in a ROM or with opkg.
