ImportError: No module named simplejson

[anonymous]

I just installed XmlRpcPlugin with easy_install -Z -U ​http://trac-hacks.org/svn/xmlrpcplugin/trunk then enabled it in trac.ini

Now I've got this error message:

ImportError: No module named simplejson

I've setting this as Severity: critical as it's a use case that fails with the default setup.

OK, so I am using Python 2.4 with Apache. Sorry for the trouble.

(In [7941]) XmlRpcPlugin: Json is still optional, but refactoring seems to have borked that. Plugin should now work again even if no Json is available. Closes #7116.
