Hi all,  
I’m trying to set up Julia at a new workplace and am having some problems with the proxy.

I’m using a fresh install of Julia 1.3 on Windows 10.  
I’ve set

```julia
ENV["HTTP_PROXY"]="http://proxy_address:proxy_port"
ENV["HTTPS_PROXY"]="http://proxy_address:proxy_port

```

In the startup.jl file, which allows PKG to successfully download most packages. However the download function still fails, preventing installation of some packages like GR and FFMPEG.  
The error is "Exception calling “DownloadFile” with “2” argument(s): “The remote server returned an error: (407) Proxy Authentication Required.”  
Anyone know how to fix this?  
Thanks

Hello,

I ran into similar issues, you might want to check out the following explanation.

> I keep getting an error when installing some packages on my work computer. I have successfully installed e.g. DataFrames and JSON packages, but have failed to install e.g. IJulia or Distributions. I am running Windows 10 Enterprise, system architecture is x86\_64-w64-mingw32, I don’t have admin privileges, Julia version is 1.2.0. The package manager gets successfully past the “Updating” and “Installation” steps but for some (not all) packages fails during the “Building” step. Below I am repro…

I don’t know if it is the same issue but I solved my proxy woes by adding a trailing / to the names:

```julia
ENV["HTTP_PROXY"]="http://proxy_address:proxy_port/"

```
