How to compile offline ?

For some reasons, I can't use the VPN, so I can't access some IP address. I compile the toit project, it shows as following:

Could I compile the project offline ?

There (at least) two places where we currently require internet access:

• for Go packages
• for Toit packages

We should be able to ensure that Toit doesn't need internet access, if the packages are already present.

I would have expected golang to use cached versions. So once the packages are there, it shouldn't need any internet anymore. I haven't tried it though.

Thanks for your explanation, if these can be cached in some github repo, it will be better for someone like me in China ...

Apparently there is a proxy for Go modules: https://github.com/goproxy/goproxy.cn
Maybe that one would work?

It's OK in office, I will try this in other place.
