Compressed JavaScript Files Not Available

[Karthik]

After installing the helioviewer application, I noticed that jquery files are not available under /lib folder.

Please see the attached screen shot of the site with Firebug results.

Do the files exist on your filesystem? What are the values you have in Config.ini for "root_dir" and "web_root_url"?

You may also want to check the permissions for the lib/ folder.

I ran apache ant command in scripts directory to generate the compressed Javascript files.

However, I encountered error in jsmin.py.

Below is the trace.

And I fixed it by changing the code of jsmin.py to run ant command. I changed the first line of the program to /usr/bin/python instead of /usr/bin/python2 of the jsmin.py file.

But even then, it did not create any compressed files in lib folder. The folder is still empty.

Moreover, these are the settings I have for "root_dir" and "web_root_url".

root_dir =/var/www

web_root_url=http://helioviewer.cs.montana.edu

See the attached screen shot of the site ...

The permission of lib folder is for the root user.

I ran the ant command with sudo command.

Thanks for reporting the python issues -- on another machine it was having
trouble because python pointed to python3 which jsmin.py is incompatible
with. The better fix would probably be to update jsmin.py (e.g. using 2to3).

The compressed JS files go in the build/ folder, not in lib. Do you see
them there?

As you are getting things set up I would recommend disabling "compress_js"
and "compress_css". That should make it easier to debug some problems.

I'm guessing that the "missing" errors you are seeing are all permissions
errors -- the apache user (www-data) does not have access to the files. As
a test you could try either making all files temporaily world readable
(e.g. chmod -R 755 /var/www), or possibly adding www-data to the group for
all files and folders in /var/www.

I updated jsmin.py to have python instead of python2.

Also, after I copied the files that I had in the previous version of the application from /lib folder (i.e., all the jquery files). the site is works now.

However, I am not able to see any recently posted videos yet. I will check the settings and try to fix it.

You can check the site at "http://helioviewer.cs.montana.edu/".

Thanks.
