P=plot(log((1+x)/(1-x)), (x, -1,1)) show(P) gives a lengthy error message which ends with ImportError: cannot import name scimath I installed sage at /home/jack/Tools One clue might be the initial message I get on initiating sage in a terminal. It reads: **************************************** sys:1: RuntimeWarning: not adding directory '' to sys.path since everybody can write to it.
I have no real clue, but I would start with strace -e file ./sage 2> log-f then write plot(sin) or something similar and then quit Sage. After that fgrep tmp_ log-f shows open(".../.sage/temp/j-op7010/12072/tmp_n3Sn3X.png", ...) = 11 etc. and fgrep EACCESS log-f finds nothing. -- Jori Mäntysalo
