To start (or restart) web2py, I typically just reboot the VPS using a
"reboot" command on a WinSCP application (a windows tool); occassionally I
use a graphical reboot button on the Rackspace control panel to reboot the
VPS.
when I use a putty application and run the "which python" command, here is
what I get
{
/usr/bin/python
}
when I use a putty application and run the "python --version" command, here
is what I get
{
Python 2.5.2
}
when I use a putty application and run the "python" command, here is what I
get
{
Python 2.5.2 (r252:60911, Oct 12 2012, 20:21:22)
[GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
}
in the python shell, when I run the "import ast" command, I get the
following
{
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named ast
}
additional FYI: to install web2py on the rackspace VPS, I used putty to and
as described in the web2py book, ran the
{
On Ubuntu:
wget http://web2py.googlecode.com/hg/scripts/setup-web2py-ubuntu.sh
chmod +x setup-web2py-ubuntu.sh
sudo ./setup-web2py-ubuntu.sh
}
just like there is a simple deployment recipe to install web2py from putty,
is there a simple recipe to upgrade the python version to 2.7 and have it
work with web2py?
Thanks for your help
