Can't activate virtualenv as non root user

Question

I can activate my virtualenv only as root user:

source myprojectenv/bin/activate
-sh: 80: source: not found

sudo su
root@ubuntu-serv:/home/user/project# source myprojectenv/bin/activate
(myprojectenv) root@ubuntu-serv:/home/user/project#

How can I fix it? I need it for Fabric deployment as non root user:

def production():
    env.host_string = 'xxx.xxx.xxx.xx'
    env.user = 'username'
    path = "/home/username/project/project"
    cd("home/username/project")
    run("sudo source projectenv/bin/activate")

Answer 1

Use the following syntax to activate the virtualenv

. myprojectenv/bin/activate

the sh shell does not have the source command.
