Error when opening a terminal under Mac OS X Sierra

[moulin...@gmail.com]

Hello,

I have installed virtualenv and virtualwrapper using "pip3 install virtualenv virtualenvwrapper" but get the following error when i source ~/.bash_profile (which includes "source /usr/local/bin/virtualenvwrapper.sh"):

-bash: /usr/local/bin/virtualenvwrapper.sh: line 126: syntax error near unexpected token `os.path.normpath'

-bash: /usr/local/bin/virtualenvwrapper.sh: line 126: `        "$VIRTUALENVWRAPPER_PYTHON" -c "import os,sys; sys.stdout.write(os.path.normpath(os.path.expanduser(os.path.expandvars(\"$1\")))+'\n')"'

I have also changed the "which python" command in virtualenvwrapper.sh into "which python3" to get a correct path (the "non-system-python" one).

Any idea about the syntax error?

Thank you for help,

Richard

Rather than modifying the which command in the script, try setting
VIRTUALENVWRAPPER_PYTHON to point to the python3 executable you want to
use, before sourcing virtualenvwrapper.sh in your bash profile.

Thank you Doug.

I have added VIRTUALENVWRAPPER_PYTHON='/usr/local/bin/python3' before the "source /usr/local/bin/virtualenvwrapper.sh" line and reset which python3 back to which python but still get the same syntax error lines.

OK, I'm going to need a little more information to help debug.

Which OS are you on?

Which version of bash?

bash --version

Which version of python?

$VIRTUALENVWRAPPER_PYTHON --version

Running the function that is reporting the error with debug tracing on
may also provide some useful information:

set -x
virtualenvwrapper_expandpath "$HOME/.virtualenvs"
set +x

Hello Doug,

I’m using MacOS X Sierra ver 10.12.6 on a Mac Book Pro (autumn 2011)

Bash version

pc38:~ Richard$ bash -version

GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin16)

Copyright (C) 2007 Free Software Foundation, Inc.

Python version

pc38:~ Richard$ $VIRTUALENVWRAPPER_PYTHON --version

Python 3.6.5

For the last lines do i have to type those 3 commands in the terminal?

I did that: see attachment

Yes, although you also need to source virtualenvwrapper.sh first (sorry,
I didn't specify that).

What I'm trying to learn is what the shell is actually executing when it
runs that virtualenvwrapper_expandpath function, since that is what is
producing the error.

Another question just occurred to me. When you set
VIRTUALENVWRAPPER_PYTHON, did you use export, like this:

export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3

[Gruaux Moulin]

No i left the virtualenvwrapper.sh file as it was

…

# 10. Run: workon temp

# 11. The virtual environment is activated.

#

# Locate the global Python where virtualenvwrapper is installed.

if [ "${VIRTUALENVWRAPPER_PYTHON:-}" = "" ]

then

    VIRTUALENVWRAPPER_PYTHON="$(command \which python) »

fi

# Set the name of the virtualenv app to use.

if [ "${VIRTUALENVWRAPPER_VIRTUALENV:-

Hi Doug,

Do you expect something from me? I may have missed something..


Thanks,

Apparently I had an issue composing or sending that last email. My
apologies.

Could you send the configuration in your .bash_profile that you have for
setting up virtualenvwrapper? Any variables you are setting and the line
you're using to source virtualenvwrapper.sh would be good.

I also need you to re-run these commands because the output you sent
before showed that the function was not defined (probably because you
had not sourced virtualenvwrapper.sh yet). If virtualenvwrapper.sh is
not in /usr/local/bin please replace that path with the path to
wherever it is installed.

export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
source /usr/local/bin/virtualenvwrapper.sh

set -x
virtualenvwrapper_expandpath "$HOME/.virtualenvs"
set +x

What I'm trying to learn is what the shell is actually executing when it
runs that virtualenvwrapper_expandpath function, since that is what is
producing the error.

OK, the function isn't being defined at all because of whatever syntax
error is being encountered.

Can you paste lines 120-130 of your copy of virtualenvwrapper.sh here?

You mentioned before making changes to the script (like to set which
version of python you were using). Did you make any other changes?

Doug

Hi Doug,

Sorry for this late answer, we have been without electricity this morning.

No except « which python3 » i din’t make other changes in virtualenvwrapper.sh.

Here the lines 120-130

function virtualenvwrapper_expandpath {
if [ "$1" = "" ]; then
return 1
else

"$VIRTUALENVWRAPPER_PYTHON" -c "import os,sys; sys.stdout.write(os.path.normpath(os.path.expanduser(os.path.expandvars(\"$1\")))+'\n')"

return 0
fi
}

[Doug Hellmann]

OK, that all looks fine.

The error you're seeing doesn't make any sense to me, and I can't
reproduce it, unfortunately.

virtualenvwrapper relies heavily on the shell's configuration, and
sometimes those settings affect the way the commands are interpreted.
Since the error has to do with parsing a line as the script is
sourced, rather than when it is run, it might be caused by something
like that.

This is an especially common source of problems reported by only
one person, so is it possible that you have some "unusual" setting(s)
in your bash profile? It might be something obscure. For example,
someone once aliased "done" which is a keyword [1].

Hi Doug,

I made a change in virtualenvwrapper.sh :

if [ "${VIRTUALENVWRAPPER_PYTHON:-}" = "" ]

then

    VIRTUALENVWRAPPER_PYTHON="$(command \which python3)"

fi

by replacing the » after python3) by a normal double-quote "

and « source virtualenvwrapper.sh » gives now
