我在 debian 服务器上设置了一个 django 项目，并安装了 virtualenvwrapper 等。它可以从命令行正常工作，但现在我想从脚本中激活它。脚本中的其他所有内容都可以正常工作，但是 virtualenvwrapper 出现错误。
这是我的脚本：
#!/bin/bash
source /usr/local/bin/virtualenvwrapper.sh
NAME="mark" # Name of the application
DJANGODIR=~/webapps # Django project directory
SOCKFILE=~/webapps/mark/run/gunicorn.sock # we will communicte using this unix socket
USER=root # the user to run as
GROUP=root # the group to run as
NUM_WORKERS=3 # how many worker processes should Gunicorn spawn
DJANGO_SETTINGS_MODULE=mark.settings # which settings file should Django use
DJANGO_WSGI_MODULE=mark.wsgi # WSGI module name
echo "Starting $NAME"
# Activate the virtual environment
cd $DJANGODIR
workon mark
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH
# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR
# Start your Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do not use --daemon)
exec ~/Envs/mark/bin/gunicorn ${DJANGO_WSGI_MODULE}:application \
--name $NAME \
--workers $NUM_WORKERS \
--user=$USER --group=$GROUP \
--log-level=debug \
--bind=unix:$SOCKFILE
和我的日志：
Starting mark
ERROR: Environment 'mark' does not exist. Create it with 'mkvirtualenv mark'.

任何帮助都感激不尽！而且我认为使用我的 root 用户是不好的，但这是我第一次。
