Whoa... wtf Powershell?!

[scowalt]

Turns out this doesn't repro with the latest Insider Preview build of Windows. I'll let you know if that changes.

[ferventcoder]

@Tom999Hall this

[Tom999Hall]

Looks like the same - this is on the latest insider Preview - Win10 x64, Build 14291

[ferventcoder]

I created an issue on this to get Microsoft's feedback - https://windowsserver.uservoice.com/forums/301869-powershell/suggestions/13028523-lastest-windows-insider-builds-collection-is-rea

@scowalt @Tom999Hall if you upgrade to the latest beta of 0.9.10, are you still seeing this error?

[Tom999Hall]

I got the same error trying to upgrade

[ferventcoder]

@Tom999Hall I just thought of that yeah. You try to use https://chocolatey.org/installabsolutelatest.ps1 and run the installer to get the beta.

[Tom999Hall]

Installed/upgraded to 0.9.10 beta Ok, but still getting
ERROR: Collection is read-only. at , : line 1

[ferventcoder]

Can you try isolating this for me?

Call:
& C:\ProgramData\chocolatey\helpers\chocolateyScriptRunner.ps1 - there should be an error, I just want to get an idea if the above error is related to something in this script or another reason.

[ferventcoder]

Add the error log or an image back here after you run this

[Tom999Hall]

[ferventcoder]

Contents of the file?

[ferventcoder]

Two things. Contents of the file and can you tell me the specific encoding of the file? (Notepad++ can provide this information easily). I'm looking for UTF-8 with or without BOM.

[ferventcoder]

Actually, line 1 - we specify parameters in a script.

[ferventcoder]

I just looked and the file for me is UTF w/BOM. So is the chocolateyInstaller.psm1 file.

[ferventcoder]

DO me a huge favor.

Create these two files:

TestWithParams.ps1:

param (
  [string]$TestVariable
)

$invocation = $MyInvocation
$argumentsPassed = $invocation.UnboundArguments -Join ' '
Write-Output "Received [$($invocation.InvocationName) $argumentsPassed]"

TestNoParams.ps1:

$invocation = $MyInvocation
$argumentsPassed = $invocation.UnboundArguments -Join ' '
Write-Output "Received [$($invocation.InvocationName) $argumentsPassed]"

Now run both as

• & C:\TestWithParams -TestVariable 'Hi' -OtherArgument 'yep'
• & C:\TestNoParams -TestVariable 'Hi' -OtherArgument 'yep'

[ferventcoder]

This was my output:

[Tom999Hall]

Here's mine ...

[ferventcoder]

Well that validates it is not params. Okay, let's incrementally add parts of the chocolateyScriptRunner.ps1 into TestWithParams.ps1 one until we find the culprit. Can you do that for me?

[Tom999Hall]

Unfortunately, I’ve got to go out for a couple of hours

[ferventcoder]

No worries, it will be here when you get back.

[ferventcoder]

https://github.com/chocolatey/choco/blob/0.9.9.11/src/chocolatey.resources/helpers/chocolateyScriptRunner.ps1 - If I had to guess, I'd believe it is $Warning that is causing the issue:

$RunNote = "DarkCyan"
$Warning = "Magenta"
$ErrorColor = "Red"
$Note = "Green"

[HemantMahawar]

@ferventcoder

Yes, bug in PowerShell in the latest insider build. Will get it fixed, in the meanwhile you can fix the issue on your side by changing (in file choco/src/chocolatey.resources/helpers/chocolateyScriptRunner.ps1)

From:
[alias("params")][alias("parameters")][alias("pkgParams")]

To:
[alias("params","parameters","pkgParams")]

[ferventcoder]

Ah! Thanks @HemantMahawar!

[ferventcoder]

This has been released in 0.9.9.12 and today's beta release for 0.9.10.

[scowalt]

Thanks for addressing this so quickly @ferventcoder !

[ferventcoder]

No worries. I didn't want to put out a 0.9.9.12 but this is a pretty gating issue for Choco, so I created the branch from the last tag and we'll have a short-lived 0.9.9.x branch.

As an aside, git is awesome. 👍

[scowalt]

(also, friendly reminder to update install.ps1 on the website 😄)

[ferventcoder]

Thanks, forgot that was changed to be hardcoded!

[ferventcoder]

Done.

[GeorgeHahn]

Quick note to anyone else pasting the fix from @HemantMahawar - the quotes are smart quotes (which is why your text search is failing). Thanks for the fix!

[ferventcoder]

Fixed. Thanks for noting that @GeorgeHahn!
