PYTHONPATH needs to be exported

[sherpya]

the .sh script does not export PYTHONPATH, you need to export it using export PYTHONPATH or prepending it to exec call

[Storyyeller]

That's weird. It works when I try it. Does this depends on the system?

[dwayneyuen]

Mine also needs to export PYTHONPATH, otherwise I get this error:
"Error while finding spec for 'enjarify.main' (<class 'ImportError'>: No module named 'enjarify')"

I'm using Python 3.4.3 on OSX Yosemite.

[Storyyeller]

Maybe it's an issue with Macs? Unfortunately, I don't have any to test on.

[sherpya]

no, it's bash (I'm on linux), you need to explicitly export or put on the exec command line, you may already have set PYTHONPATH, so your system does not expose the problem

I'm using Python 3.4.3 on OSX 10.10.3
ln -s "$PWD/enjarify.sh" ~/bin/enjarify
Using python3 as Python interperter
/usr/local/bin/python3: Error while finding spec for 'enjarify.main' (<class 'ImportError'>: No module named 'enjarify')

[Storyyeller]

It looks like I have PYTHONPATH set to /usr/local/buildtools/current/sitecustomize, but I can't imagine how that would make a difference.

It's weird that on your system you have to explicitly export it, while on mine, merely setting it seems to be enough.

[dwayneyuen]

Are you running from the enjarify directory or somewhere else and using a symlink?

[Storyyeller]

I'm running from elsewhere using a symlink.

Anyway, I went ahead and added export. Does it work now?

[dwayneyuen]

Working for me. :)

[moneytoo]

Well, the output of readlink is blank so it prevents me from calling enjarify from any outside dir (it's same for both macOS/Linux).

echo $(dirname "$(readlink "${BASH_SOURCE[0]}")")

prints .

[tiann]

readlink doesn't work for me, too. my OS version is Mac OSX 10.11; I change it to this:

$(cd dirname $0; pwd)

And it worked for me.

Copy the following to enjarify.sh, you can solve this problem. good luck.

function guess {
	if [ -z "$PYTHON" ]; then
		result=$($1 -c "print(range)" 2>/dev/null)
		if [ "$result" = "<class 'range'>" ]; then
			PYTHON=$1
		fi
	fi
}

guess "pypy3"
guess "python3"
guess "pypy"
guess "python"

#Gets the root path of the current script
getCurrentShellRootPath()
{
oldPath=`pwd`
SOURCE="$1"
while [ -h "$SOURCE"  ]; do # resolve $SOURCE until the file is no longer a symlink
    DIR="$( cd -P "$( dirname "$SOURCE"  )" && pwd  )"
    SOURCE="$(readlink "$SOURCE")"
    [[ $SOURCE != /*  ]] && SOURCE="$DIR/$SOURCE" # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located
done
DIR2="$( cd -P "$( dirname "$SOURCE"  )" && pwd  )"
echo ${DIR2}
cd $oldPath
}

if [ -z "$PYTHON" ]; then
	echo "Unable to find python3 on path"
else
	echo "Using $PYTHON as Python interpreter"

	# Find location of this bash script, and set its directory as the PYTHONPATH
	#export PYTHONPATH=$(dirname "$(readlink "${BASH_SOURCE[0]}")")
	#Modify the path to PYTHONPATH
	shellRootPath=`getCurrentShellRootPath $0`
	export PYTHONPATH=${shellRootPath}
	

	# Now execute the actual program
	exec $PYTHON -O -m enjarify.main "$@"
fi

it worked! Thanks!
