Missing kpsewhich command causes jcvi to report an error

Recently, the installation of jcvi under linux system for collinear analysis is smooth, but there are always errors at run time.

MCscan error message:

After searching the query, we know that it is caused by the missing kpsewhich command in linux, so install the command as follows:

Sudo yum install tetex-latex tetex-doc tetex-fontssudo yum install texlive tex-live-latex

After installation, run again and pass smoothly.
