Hi,

Just saw this on my RHEL 7 test box. This is pgadmin4 1.0rc1, Python 2.7,
python-flask-babel-0.11.1:

# /usr/bin/python2 /usr/lib/python2.7/site-packages/pgadmin4-web/pgAdmin4.py
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/pgadmin4-web/pgAdmin4.py", line 58, in <module>
    app = create_app()
  File "/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/__init__.py", line 226, in create_app
    driver.init_app(app)
  File "/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/utils/driver/__init__.py", line 40, in init_app
    DriverRegistry.load_drivers()
  File "/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/utils/driver/registry.py", line 88, in load_drivers
    module = import_module(module_name)
  File "/usr/lib64/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/utils/driver/psycopg2/__init__.py", line 33, in <module>
    from pgadmin.utils.exception import ConnectionLost
  File "/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/utils/exception.py", line 15, in <module>
    from pgadmin.utils.ajax import service_unavailable
  File "/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/utils/ajax.py", line 124, in <module>
    def not_implemented(errormsg=_('Not implemented.'), info='', result=None, data=None):
  File "/usr/lib/python2.7/site-packages/flask_babel/__init__.py", line 539, in gettext
    t = get_translations()
  File "/usr/lib/python2.7/site-packages/flask_babel/__init__.py", line 208, in get_translations
    return support.NullTranslations()
AttributeError: 'module' object has no attribute 'NullTranslations'

What am I missing here?

Hmm, not sure. Questions:

- What version of Babel?
- I assume (hope) you haven't changed config.py, but what's in
config_distro.py and config_local.py?
- Is the web/pgadmin/translations/ directory present and containing
files (a test French message catalog)?
- Is babel.cfg present?

$ cat /usr/lib/python2.7/site-packages/pgadmin4-web/config_local.py
SERVER_MODE = False
HTML_HELP = '/usr/share/doc/pgadmin4-docs/en_US/html/'

I don't have config_distro.py

Yes:

/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/translations
/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/translations/fr
/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/translations/fr/LC_MESSAGES
/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/translations/fr/LC_MESSAGES/messages.mo
/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/translations/fr/LC_MESSAGES/messages.po

> - Is babel.cfg present?

Yes:
$ cat /usr/lib/python2.7/site-packages/pgadmin4-web/babel.cfg
[python: **.py]
[jinja2: **/templates/**.html]
[jinja2: **/templates/**.js]
extensions=jinja2.ext.autoescape,jinja2.ext.with_

Argh. Upgrading it to 1.3 fixed the issue. Sorry for the noise.

That's really old - I have 2.3.4.

Please move those two lines into config_distro.py - that's intended
for distro-specific configuration, whilst config_loca.py is for
user-specific.

Thanks.
