I have an old version of posh-git that I want to update (while trying to solve slow powershell start ups)
I've pulls latest from the repo and when I am trying to do .\install.ps1
I get
It seems posh-git is already installed...
How do I update posh-git?
回答1:
All it does is look if the script is being sourced in your profile:
$profileLine = ". '$installDir\profile.example.ps1'"
if(Select-String -Path $PROFILE -Pattern $profileLine -Quiet -SimpleMatch) {
Write-Host "It seems posh-git is already installed..."
return
}
Since it seems to have the installDir as the folder from which you run the install script, merely upgrading the folder with the newer version of posh-git should give have updated the files already.
If you are not comfortable with that, just remove the line that sources the profile.example.ps1
in your profile and run the install again :)
回答2:
If installed via PsGet, you can just run
Update-Module posh-git

I had installed via PsGet, so I renamed the folder
C:\Users\[myName]\Documents\WindowsPowerShell\Modules\posh-git
and re-ran
Install-Module posh-git
It downloaded the latest but told me it was already installed, probably because I hadn't removed the lines from Microsoft.PowerShell_profile.ps1. That was all I needed, though.
