How to Install posh-git Behind Firewall

Scope

Trying to install posh-git following the installation note, but getting some error.

Prerequsite

Troubleshooting

$ Get-PSRepository
WARNING: Unable to find module repositories.

These errors are indicating that there are no repository available. I have installed posh-git many times and this doesn't look normal to me, since I am also having some proxy issue with my new machine, I am suspecting it could be a firewall / network issue.

I tried some of this, but not much luck.


WARNINGS: Do not use npm install -g posh-git. It is a replica of the original posh-git but not the same package as the genuine one. Look at the package note, it stated that "This is a new project, it's currently working only on Linux..." and the author is not dahlbyk.

$ Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Verbose -Force

$ choco install poshgit
# I cannot even get chocolatey to install because of the same proxy issue... so not an option

$ (new-object Net.WebClient).DownloadString("http://psget.net/GetPsGet.ps1") | iex install-module posh-git

Exception calling "DownloadString" with "1" argument(s): "The remote server returned an error: (407) Proxy Authentication Required."

Solution

Finally, I went back to the basics, I bypassed the firewall but a direct git clone to the source code and solved the issue.

$ git clone https://github.com/dahlbyk/posh-git.git
$ .\posh-git\install.ps1

Extra

I found the default color was a little too dark against the dark background color, so I made some changes in ~/.git/config to make it easier to read.

[color]
    ui = true 
[color "status"]
    changed = magenta bold
    untracked = yellow bold

Better contrast after changing the color
