Jika Anda mendaptkan error, seperti berikut ketika proses konversi Latex ke Image di browser :

convert: FailedToExecuteCommand `'gs' -sstdout=%stderr -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4 '-r360x360' '-sOutputFile=/var/tmp/magick-424wzOPTYa4oUUs%d' '-f/var/tmp/magick-424b_MRRkTxfwQT' '-f/var/tmp/magick-4247LVcZCDEEICo'' (1) @ error/pdf.c/InvokePDFDelegate/290.

Maka tambahkan konfigurasi berikut di /usr/local/etc/php/7.1/php-fpm.d/www.conf (sesuaikan dengan versi PHP yang And gunakan) :

env[PATH] = /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
