i have the same err.

[nanw-juniper]

I had the same issue, here is what I did:

cd third_party
python3 fetch_packages.py
if above cmd failed to get at some url, like Url did not work: https://github.com/joyent/http-parser/archive/v2.1.tar.gz
then try:
python3 fetch_packages.py --site-mirror http://10.84.56.27

then try build again:

scons vrouter
