I found something out myself, the variant names have changed. You can look at the available variants in this file:
I am trying to install ROS unstable on my Mac and the rosinstall command fails with a traceback:Traceback (most recent call last):File "/opt/local/Library/Frameworks/Python.framework/Versions/Current/bin/rosinstall", line 551, in <module>sys.exit(not rosinstall_main(sys.argv))File "/opt/local/Library/Frameworks/Python.framework/Versions/Current/bin/rosinstall", line 508, in rosinstall_mainresult = insert_source_yaml(source_yaml, a, observed_paths, aggregate_source_yaml)File "/opt/local/Library/Frameworks/Python.framework/Versions/Current/bin/rosinstall", line 385, in insert_source_yamlif not element[k]:TypeError: string indices must be integers, not strWhich after some digging I found out is an unhandled exception here in the rosinstall.helpers.get_yaml_from_uri function:def get_yaml_from_uri(uri):
# now that we've got a config uri and a path, let's move out.u = urlparse.urlparse(uri)f = 0if u.scheme == '': # maybe it's a local file?try:f = open(uri, 'r')except IOError, e:print >> sys.stderr, "ahhhh error opening file: %s" % ereturn Noneelse:try:f = urllib2.urlopen(uri)except IOError, e:print >> sys.stderr, "ahhhhh got an error from the interwebs: %s" % eif not f:print >> sys.stderr, "couldn't load config uri %s" % urireturn Nonetry:y = yaml.load(f); #<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< This returns the string "Variant "base" does not exist in the unstable disro file." rather than throwing an exception
except yaml.YAMLError, e:print >> sys.stderr, "ahhhhhhhh, yaml parse error: %s" % e # long ahhreturn Nonereturn yWhich gets returned and manifested as the TypeError above.So, the real problem is that the rosinstall url from http://www.ros.org/wiki/unstable/Installation/Ubuntu/source and http://www.ros.org/wiki/unstable/Installation/OSX, https://code.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=unstable&variant=base&overlay=no, returns the string "Variant "base" does not exist in the unstable disro file." rather then yaml.This is true of variants "ros" and "base", but "pr2" seems to return yaml, I might try to install using it for now.Is there a reason that unstable doesn't have "ros" and "base" or are things just changing with unstable's variant layout atm?Thanks,
