Posh-git: Can't install latest release

[ownmaster]

Hi,

I can't install posh-git via choco or install-package/install-module.
When I install using install-package or install-module posh-git gets installed (I can see it in 'modules' folder), but import-module posh-git doesn't bring it.
If I install using choco setup fails:

Get-BinRoot is going to be deprecated in v1 and removed in v2. It has been replaced with Get-ToolsLocation (starting with v0.9.10), however many packages no longer require a special separate directory since package folders no longer have versions on them. Some do though and should continue to use Get-ToolsLocation.

I only managed to install it by first installing PsGet and then running install-module, then manually addding import-module to profile. But in this case I've got version 0.7.0.

System info:

posh-git version: 0.6.1, PSVersion: 5.1.14393.693, git version 2.10.1.windows.1, OS: Microsoft Windows NT 10.0.14393.0

[rkeithhill]

Since you are on PS 5.1, you shouldn't need to use Chocolatey. You say you first installed PSGet, but you shouldn't have to do that. PS v5 and higher come with two modules: PackageManagement (manager of pkg managers) and PowerShellGet. The latter supersedes the need for the older, community created PSGet.

If posh-git did get installed into $Home\Documents\WindowsPowerShell\Modules\posh-git\0.6.1.20160330, let's make sure it installed correctly. First, import from that location e.g.:

Import-Module $Home\Documents\WindowsPowerShell\Modules\posh-git\0.6.1.20160330\posh-git.psd1

Also check for the existence of the following file:

Get-Item -Force $Home\Documents\WindowsPowerShell\Modules\posh-git\0.6.1.20160330\PSGetModuleInfo.xml

If that file doesn't exist, then you probably installed with the old PSGet. If it exists, then it was installed with PowerShellGet - which means you can use Update-Module posh-git to update to newer versions.

OK, so if the above import worked but "Import-Module posh-git" does not work, it means your PSModulePath environment variable is borked. Output its value with $Env:PSModulePath. It should look like this:

C:\Users\Keith\Documents\WindowsPowerShell\Modules;C:\Program Files\WindowsPowerShell\Modules;C:\WINDOWS\system32\WindowsPowerShell\v1.0\Modules\;C:\Program Files\Microsoft Message Analyzer\PowerShell\

Note that it is the existence of C:\Users\<username>\Documents\WindowsPowerShell\Modules that allows PowerShell to load modules from your Modules directory. If that doesn't exist, then go to the System Properties and edit the PSModulePath environment variable to add this path.

RE version 0.7.0, you have a pre-release of 0.7.0. When 0.7.0 releases (shortly - hopefully) you will need to remove that version and then install the released version from the PSGallery.

Hi,

I was having the exact same problem when I found out this issue report (I didn't know not to use chocolatey for installation). Then I followed your readme.md.

Install-Module -Name posh-git seemed to have succeeded. Get-Module -Name posh-git returns the following:

ModuleType Version    Name     ExportedCommands
---------- -------    ----     ----------------
Script     0.6.1.2... posh-git {Add-SshKey, Enable-GitColors, Get-AliasPattern, Get-GitDirectory...}

The Import-Module posh-git command does not output anything (I'm assuming this is a good thing) but the command prompt does not change.

My PSModulePath includes C:\Users\<username>\Documents\WindowsPowerShell\Modules.

PSversion:

Major  Minor  Build  Revision

PS: In your readme, you mention a command Add-PoshGitToProfile. posh-git does not seem to export it. Also, $GitPromptSettings does not contain DefaultPromptSuffix, it has the following:

We haven't release 0.7.0 to the PSGallery yet. You won't see the prompt change on import until 0.7.0 releases. Hopefully in the coming week (or two). In the mean time execute notepad $profile.CurrentUserAllHosts and add the following to it:

function prompt {
    $origLastExitCode = $LASTEXITCODE
    Write-Host $ExecutionContext.SessionState.Path.CurrentLocation -NoNewline
    Write-VcsStatus
    $LASTEXITCODE = $origLastExitCode
    "$('>' * ($nestedPromptLevel + 1)) "
}

Import-Module posh-git

Once 0.7.0 comes out and you run Update-Module posh-git, you will be able to remove the prompt function from your profile (but leave in the import command).

[canpolat]

@rkeithhill Thank you for the prompt response. It works after applying your suggestion.

[dahlbyk]

Back to the original issue: I believe the removal of the call to install.ps1 in https://github.com/dahlbyk/posh-git/commit/c2cb856c8a2964b504ad462c01d51e2c6d404752 was premature; a clean install over in #358 doesn't work either. 😦

[rkeithhill]

@dahlbyk :-( indeed. What can I help with (later tonight)?

[canpolat]

Sorry for hijacking the thread. In my setup, the C:\ProgramData\chocolatey\lib\poshgit directory did not exist when I got the Error while running 'C:\ProgramData\chocolatey\lib\poshgit\tools\chocolateyInstall.ps1'. error. Not sure if that helps with anything, though :)

[dahlbyk]

@canpolat please confirm your Chocolatey version?

All: #383 should fix at least part of the problem. Unfortunately I need to merge to confirm. (Also something about our Chocolatey package that will be fixed by #358.)

[dahlbyk]

@ownmaster @canpolat I just tested a clean choco install poshgit (choco v0.9.9.6) without issue.

@dahlbyk I'm on a different PC now but I'm pretty sure my chocolatey version was 0.10.3.

[dahlbyk]

If anyone cares to dig into this, I pushed a preview release of 0.7 and Chocolatey package verification failed with this same error: https://github.com/dahlbyk/posh-git/pull/358#issuecomment-276156658.

[dahlbyk]

I haven't had a chance to dig in, but the full error trace is available here: https://gist.github.com/choco-bot/8fd09f341ed80aa5cf6ae01f39b49763

Here's the specific error:

I did not expect so many posts here, but will try to make everything clear :)

I never said I first installed PsGet. If talking about order:
1) I tried choco (I know I don't have to use choco, I just like to use it)
2) Tried install-module
3) Tried install-package
4) And only after all that failed I installed PsGet, and then installed posh-git using PsGet

I know what PsGet is, but that was the only way that worked in my situation.
The system before all described actions was brand new (it is actually brand new laptop, with preinstalled Windows 10 Home 64bit).

Now, I removed working posh-git and PsGet and tried again install-module. It is installed into c:\Program Files\WindowsPowerShell\Modules\posh-git\0.6.1.20160330\. PSGetModuleInfo.xml is there. $env:PSModulePath is OK - C:\Users\username\Documents\WindowsPowerShell\Modules;C:\Program Files\WindowsPowerShell\Modules;C:\Windows\system32\WindowsPowerShell\v1.0\Modules.
But import-module doesn't give any result.
Below is output of Import-Module posh-git -Verbose:

@ownmaster did you try the suggestion at: https://github.com/dahlbyk/posh-git/issues/381#issuecomment-276080295

I had the same problem and following @rkeithhill's comment solved it for me.

[rkeithhill]

@ownmaster

But import-module doesn't give any result.

Import won't give any result if the module imports without problems. That's just how PowerShellGet\Import-Module works. However, once 0.7.0 releases, importing posh-git should change the default prompt function to display Git status summary info when in a Git repo. However, if you already have a prompt function defined in your PowerShell profile, posh-git will not modify the prompt.

[dahlbyk]

New error! :rage: Suppose I should upgrade Chocolatey so I can reproduce locally.

However, if you already have a prompt function defined in your PowerShell profile, posh-git will not modify the prompt.

Nothing was defined in my profile. I supposed that profile should be modified automatically during install. Copied and modified profile posh-git configuration from another PC, now I have modified prompt.

[dahlbyk]

I supposed that profile should be modified automatically during install.

It used to (see #383). Still trying to get back to the point where that works again. ☹️

[ownmaster]

383 title says about choco. What about native PowerShell installation methods, did they also break at some point?

[rkeithhill]

@ownmaster The native PowerShell installation method has not been updated to 0.7.0. It is still installing 0.6.1.20160330 (released last year).

Once a new user has installed 0.7.0 via the PowerShellGet\Install-Module (or Update-Module) command, they only need to run Add-PoshGitToProfile to have the Import-Module posh-git command to their profile script. However, since you've already done this (manually), you won't need to do anything else once you've updated to 0.7.0.

:ok: I _think_ I have everything cleared up. If anyone here still wants to use Chocolatey, try this:

choco install poshgit --version=0.7.0-pre4

[bforrest]

@dahlbyk using choco install poshgit --version=0.7.0-pre4 worked like a charm.

I was previously getting the "Cannot bind arguement to parameter 'LiteralPath'... error.

Thank you.

@dahlbyk how to load posh-git after 0.7.0-pre4 installation via choco?

[rkeithhill]

Executing Import-Module posh-git or restarting PowerShell doesn't load the module? Or maybe you have to supply the path to Import-Module e.g. Import-Module C:\tools\poshgit\posh-git.psd1. Or maybe that path should have the version in it?

[ownmaster]

Yeah, forgot that module is installed into location which is not in PowerShell paths list. Added it manually.

BTW, when 0.7.0 is initially loaded it shows prompt as ~> but after any directory change it becomes regular c:\folder. Is it by design?

[rkeithhill]

Yes and that is something that is currently under discussion at #386. Basically, since the posh-git provided prompt is a single line - with a lot of info to potentially display - we substitute ~ for your home directory e.g. C:\Users\ownmaster. If you are not in or under your home dir, you will see a full path. We are likely to add a $GitPromptSettings property to allow you to control that. At the moment, the debate is over what the default should be (to abbreviate or not).

@ownmaster Do you consider this issue fixed - considering you can only install the latest pre-release from Chocolatey ATM?

[canpolat]

I did not have access to that PC yesterday. Today, I tryied the 0.7.0-pre4 version and the installation wen thru. Thank you for the quick response.

[dahlbyk]

0.7.0 is Coming Soon, but I went ahead and pulled the important bits from #358 into master anyway to fix non-prerelease installs. Thanks, again, for the bug report @ownmaster!

[ownmaster]

@rkeithhill I guess yes, it is fixed - now I can install. :) I hope in 0.7.? release it will be added to profile automagically after setup.

[rkeithhill]

it will be added to profile automagically after setup.

If using Chocolatey, yes. But no if using PowerShellGet\Install-Module. The latter just downloads, unzips and copies the bits to the specified Modules folder - nothing more.

We started down the automagical path with https://github.com/dahlbyk/posh-git/pull/361, but couldn't reliably decide if we should add to profile or not. We ended up with the deterministic Add-PoshGitToProfile instead.
