我正在使用以下PowerShell脚本通过Octopus Deploy步骤安装dotnetcore-windowshosting版本1.1.1。
ChocolateyPackageId等于“dotnetcore-windowshosting”和 $ ChocolateyPackageVersion等于“1.1.1”。
但是,目标计算机安装了新版本的DotNetCore.1.0.4_1.1.1-WindowsHosting.exe,而不是由Chocolatey软件包安装的版本。因此,会出现错误,提醒我目标计算机已安装了较新版本。
如何在脚本中使用subprocess
安装软件包,但是,如果已安装软件包(或更新版本),请忽略并不引发错误?
cinst

继续使用您正在处理的脚本,但是请检查您正在安装的内容的退出代码,它可能有一个有效的退出代码,指定已安装较新的版本。
实现您正在寻找的目标的最佳方式可能已经存在。 Chocolatey for Business具有sync命令和自动同步功能。 https://chocolatey.org/docs/features-synchronize
如果您运行choco sync
然后调用了您的安装,那么您将拥有由Chocolatey管理的该软件包的更新版本。因此它会忽略你的脚本。
choco sync
choco upgrade <name> -y <options>
如果您的源中有更新的版本,如果未安装和升级软件包,则此处升级将实现安装

免责声明:这是hacky。并没有很好的方式。
function Test-ChocolateyPackageInstalled {
Param (
[ValidateNotNullOrEmpty()]
[string]
$Package
)
Process {
if (Test-Path -Path $env:ChocolateyInstall) {
$packageInstalled = Test-Path -Path $env:ChocolateyInstall\lib\$Package
}
else {
Write-Warning "Can't find a chocolatey install directory..."
}
return $packageInstalled
}
}
$package = "dotnetcore-windowshosting"
if (Test-ChocolateyPackageInstalled -Package $package) {
Write-Warning "Package is already installed"
}
else {
choco install $package -confirm
}
我只是通过Chocolatey安装了这个,所以当其他人手动安装时,我会很难测试你的场景,但这种方法可能有用。
因此,请注意,这可能无法完全解决您的问题;但它可以帮助未来的读者。

感谢所有建议。以下似乎对我有用
$chocolateyBin = [Environment]::GetEnvironmentVariable("ChocolateyInstall", "Machine") + "\bin"
if(-not (Test-Path $chocolateyBin)) {
Write-Output "Environment variable 'ChocolateyInstall' was not found in the system variables. Attempting to find it in the user variables..."
$chocolateyBin = [Environment]::GetEnvironmentVariable("ChocolateyInstall", "User") + "\bin"
}
$cinst = "$chocolateyBin\cinst.exe"
$choco = "$chocolateyBin\choco.exe"
if (-not (Test-Path $cinst) -or -not (Test-Path $choco)) {
throw "Chocolatey was not found at $chocolateyBin."
}
if (-not $ChocolateyPackageId) {
throw "Please specify the ID of an application package to install."
}
$chocoVersion = & $choco --version
Write-Output "Running Chocolatey version $chocoVersion"
$chocoArgs = @()
if([System.Version]::Parse($chocoVersion) -ge [System.Version]::Parse("0.9.8.33")) {
Write-Output "Adding --confirm to arguments passed to Chocolatey"
$chocoArgs += @("-y", "")
}
if (-not $ChocolateyPackageVersion) {
Write-Output "Installing package $ChocolateyPackageId from the Chocolatey package repository..."
& $cinst $ChocolateyPackageId $($chocoArgs)
} else {
Write-Output "Installing package $ChocolateyPackageId version $ChocolateyPackageVersion from the Chocolatey package repository..."
& $cinst $ChocolateyPackageId -Version $ChocolateyPackageVersion $($chocoArgs) --force
}
$codes = $IgnoreExitCodes -split ','
if ($codes -Contains $lastExitCode)
{
exit 0
}
