Why is virtualenv not setting my terminal prompt?

Whatever is setting up your git-aware prompt is probably defining the PROMPT_COMMAND function. Try adding this to the end of your .bashrc file.

add_venv_info () {    if [ -z "$VIRTUAL_ENV_DISABLE_PROMPT" ] ; then        _OLD_VIRTUAL_PS1="$PS1"        if [ "`basename \"$VIRTUAL_ENV\"`" = "__" ] ; then            # special case for Aspen magic directories            # see http://www.zetadev.com/software/aspen/            PS1="[`basename \`dirname \"$VIRTUAL_ENV\"\``] $PS1"        elif [ "$VIRTUAL_ENV" != "" ]; then            PS1="(`basename \"$VIRTUAL_ENV\"`)$PS1"        fi    fi    export PS1}PROMPT_COMMAND=add_venv_info

What are Aspen magic directories? I have no idea; this was code copied from an activate script to demonstrate how to use PROMPT_COMMAND to include virtual environment information into your propmt. If they aren't relevant to your situation, you can simply add the PS1=... assignment that you want. The only really important parts are 1) Checking VIRTUAL_ENV_DISABLE_PROMPT and 2) making the desired assignment to PS1.

I had the same issue, but the above solution didn't work for me.

I ended up doing this:(mind that there's an additional space to separate the (virtenv) from the $

# Virtual ENV stuffadd_venv_info () {    if [ -z "$VIRTUAL_ENV_DISABLE_PROMPT" ] ; then        VIRT_ENV_TXT=""        if [ "x" != x ] ; then            VIRT_ENV_TXT=""        else            if [ "`basename \"$VIRTUAL_ENV\"`" = "__" ] ; then                # special case for Aspen magic directories                # see http://www.zetadev.com/software/aspen/                VIRT_ENV_TXT="[`basename \`dirname \"$VIRTUAL_ENV\"\``]"            elif [ "$VIRTUAL_ENV" != "" ]; then                VIRT_ENV_TXT="(`basename \"$VIRTUAL_ENV\"`)"            fi        fi        if [ "${VIRT_ENV_TXT}" != "" ]; then           echo ${VIRT_ENV_TXT}" "        fi    fi}# Now we construct the prompt.# in my case a bunch of lines constructing the complete PS1# somewhere call the add_venv_info function like below        PS1=${PS1}"\[\$(job_color)\]\n\$(add_venv_info)\$\[${NC}\] "
