Python 3.3, so I've tweaked the patch a little (see attached). I know
the current code has worked on some 3.x versions but I don't know
which exactly as I don't currently have them here, but I'll bet it was
3.2 or below. Ashesh - can you have the most appropriate person from
the team check this works on 3.0 through 3.5 please?Can you please take a look at it?Sure.
Following is the analaysis of compiling runtime environment on Ubuntu14.04 with various python versions.
1. When compiled with Python-3.2
It compiled successfully but on running pgAdmin4 executable it shows syntax error:
(py32)surinder@ubuntu:~/Developments/pgadmin4/runtime$ echo $PYTHONPATH
:/home/surinder/.virtualenvs/py32/lib:/home/surinder/.virtualenvs/py32/lib/python3.2/site-packages
(py32)surinder@ubuntu:~/Developments/pgadmin4/runtime$ ./pgAdmin4
Python path: ""
Webapp path: "/home/surinder/Developments/pgadmin4/web/pgAdmin4.py"
Traceback (most recent call last):
File "/home/surinder/Developments/pgadmin4/web/pgAdmin4.py", line 24, in <module>
from pgadmin import create_app
File "/home/surinder/Developments/pgadmin4/web/pgadmin/__init__.py", line 254
if response.content_type == u'text/html; charset=utf-8':
^
SyntaxError: invalid syntax
"Failed to launch the application server, server thread exiting."
I got same error when I run pgAdmin4 with python installed from repository and with python compiled from source.
Upon further investigation it seems to be encoding issue.
2. pgAdmin4 compiled and run successfully on Python-3.3 & 3.4.
I didn't face the error @asser is facing while running pgAdmin4.

Cool - many thanks!
