Error, do this: mount -t proc proc /proc

I am getting this error both on pushes from local to remote and when starting a bash console on PA.

I have been away from PA for a while, but I don't think I've seen this error before.

What happens if you try to just ssh in without the git push?

The ssh works fine, but I get that same "proc" error msg. Here are the last few lines of verbose output for the ssh command ssh -v stevetone@ssh.pythonanywhere.com:

Error, do this: mount -t proc proc /proc

That sounds like maybe your bashrc or something is doing something that requires proc. Did you recently add something to your bashrc? (since that will get run upon ssh-ing in)

Traditionally, you could never access /proc

I do not think I have ever edited the default .bashrc file. At least not recently. Here it is:

# Load up standard site-wide settings.
source /etc/bashrc
source virtualenvwrapper.sh
SSH_ENV=$HOME/.ssh/environment
# start the ssh-agent
function start_agent {
    echo "Initializing new SSH agent..."
    # spawn ssh-agent
    /usr/bin/ssh-agent | sed 's/^echo/#echo/' > "${SSH_ENV}"
    echo succeeded
    chmod 600 "${SSH_ENV}"
    . "${SSH_ENV}" > /dev/null
    /usr/bin/ssh-add
}
if [ -f "${SSH_ENV}" ]; then
     . "${SSH_ENV}" > /dev/null
     ps -ef | grep ${SSH_AGENT_PID} | grep ssh-agent$ > /dev/null || {
        start_agent;
    }
else
    start_agent;

There is a "ps" command in that .bashrc. That appears to be generating the error message.

Is there a default .bashrc that I should have?

I setup a free new account and copied the .bashrc from there. Problem solved :)

I'm seeing this error when I run pipenv install in my bash console here on Pythonanywhere.

Yes, it looks like pipenv doesn't work with our virtualization system right now :-(

FWIW, I see that error, but apart from that, it seems to play nicely with my virtualenv, and actually installs what I ask it to.

Interesting! Maybe the sandboxing system is only causing problems with a non-essential feature of pipenv. We'd love to know how you get on with it.
