Mac environment, after boot2docker start
Previously normal, the system go environment was upgraded.
brew upgrade goTo 1.4, it was 1.3 before. Delete all relevant files and start over.
boot2docker initI only finished downloading ios and didn’t produce the certificate file. It feels like there is a problem here. I should have been prompted to generate the completion certificate before.
boot2docker start -v, found a lot of output
Connecting to tcp://localhost:2022 (attempt #0) boot2docker
Under google, it is found that there is less in /etc/host.
