Suggestions at TexStudio and Inkscape were followed as my problem also involves the use of --shell-escape. No improvement using methods suggested there. Here is my situation:
I am attempting to use TeXstudio to compile documents requiring access to Inkscape and also the use of --shell-escape. Despite having installed both TeXstudio and Inkscape from apt get install (compliant with answer given in noted URL), TeXstudio insists it cannot find Inkscape. I have put the paths to Inkscape in my .bashrc file and echo $PATHdefinitely shows Inkscape. Moreover, Inkscape does appear in the GUI of Linux Mint. Besides the error message
Class pagelayout Error: Inkscape not installed. Shadow not created.
I also get this error regardless of whether Inkscape is called, or not:
tput: No value for $TERM and no -T specified
Hopefully, the 2nd error re: $TERM will be a useful diagnostic.
