After I command python -m readme2tex --output result.md README.md, I got this error message but I don't know how to handle it

'$cost=\sum { { (y-\bar { y } ) }^{ 2 } } +\lambda \sum { { \left| W \right|  }^{ 2 } }$' has warnings during compilation. See /var/folders/zb/9sv0pm4x7v1c9ng44rpbqs7r0000gn/T/readme2tex-k3308sx3/6cfc9fee460f304e0df2af7fcf3336f8

I think there are some faults in my LATEX code but not sure.
Can anybody help me?

You need to install dvisvgm onto your system (it does not come pre-installed with this package).
