I am running Qiime on a linux virtual Box 64Bts.
When I am on TERMINAL AND I run the command
qiime@qiime-VirtualBox:~$ pynest it works good. I can see the expected output.
But when a call from php,
echo shell_exec("pynest"); or
echo shell_exec("pynest.py; echo $?"); or
echo shell_exec("pynest; echo $?"); it not works. I should have the expected output. Instead I have the number 127.
Is it a kind of "software not found"?
How to solve this issue?
