bake download error

[basant subba]

Hello everyone. As mentioned in some tutorial when I try to download some dependency file using the bake command "./bake.py download", I get this error.

 >> Searching for system dependency python-dev - OK
 >> Searching for system dependency pygraphviz - OK
 >> Searching for system dependency pygoocanvas - OK
 >> Downloading pybindgen-0.17.0.868 - Problem
 > Problem: Optional dependency, module "pybindgen-0.17.0.868" failed
   This may reduce the  functionality of the final build.
   However, bake will continue since "pybindgen-0.17.0.868" is not an essential dependency.
   For more information call bake with -v or -vvv, for full verbose mode.

   This may reduce the  functionality of the final build.
   However, bake will continue since "netanim-3.105" is not an essential dependency.
   For more information call bake with -v or -vvv, for full verbose mode.

 >> Downloading ns-3.20 - Problem
 > Error:  Critical dependency, module "ns-3.20" failed
   For more information call Bake with --debug and/or -v, -vvv, for full verbose mode (bake --help)

bake is not able to download 3 files : "pybindgen-0.17.0.868", "netanim-3.105" and "ns-3.20".

How do I fix this error? Thanks and regards...!!

I had similar issues and found that my env proxy setting were incorrect. You might want to check that http_proxy and https_proxy are correct.
