I met a building error when I tried to add a package in [here](https://github.com/mexsser/POMDPIDMModel.jl):

```julia

```

Any idea for this?

The `download()` failed, although there is a fallback. Your system is probably not allowed to download from GH or our download server. Are there any firewall restrictions at your site?

What kind of system are you using (from which country)?

Yes, I come from China, and there are firewall restrictions. But I have solved the firewall problem through a proxy.  
The current situation is that when I use the proxy, I can install the GR package normally, but I cannot install the POMDPIDMModel package (since I am trying to run [the program here](https://github.com/mexsser/POMDPIDMModel.jl), this package is what I really need, and installing the GR package is because the POMDPIDMModel package requires it):

I use ubuntu16.04, and the Julia version is 1.4.2.  
Any idea for this situation?

This problem has been solved by setting the proxy correctly (I made some mistakes before setting the proxy).
