英文:
Chocolatey command to verify installed package regardless of chocolatey 1/2 version
问题
Chocolatey重新设计了“choco list”命令。从版本2.0开始，不再接受--lo（=本地）参数，每次调用都被视为针对本地软件包。
- Chocolatey 1.1：它列出了本地软件包（"1个软件包已安装。"）
- Chocolatey 2.0：错误（"无效的参数--lo。该参数已从列表命令中删除，无法使用。"）
choco list -e procmon
- Chocolatey 1.1：它列出了远程软件包（"找到1个软件包。"）
- Chocolatey 2.0：它列出了本地软件包（"1个软件包已安装。"）
我使用PowerShell脚本来维护各种Chocolatey版本的1000台计算机。我需要一个通用的命令来查找是否安装了Chocolatey软件包。无论Chocolatey的版本如何，都能正常工作。如何实现？
英文:
Chocolatey reworked "choco list" command. Since version 2.0 it no more accepts --lo (=local) argument and every call is considered against local packages.
choco list --lo -e procmon
- Chocolatey 1.1: it lists local package ("1 packages installed.")
- Chocolatey 2.0: error ("Invalid argument --lo. This argument has been removed from the list command and cannot be used.")
choco list -e procmon
- Chocolatey 1.1: it lists remote package ("1 packages found.")
- Chocolatey 2.0: it lists local package ("1 packages installed.")
I use PowerShell scripts to maintain 1000 machines with various chocolatey versions. I need universal command to find if chocolatey package is installed. The command which works regardless on chocolatey version. How to do it?

在Chocolatey 1.*和2.*中，这应该可以工作：
choco list --lo --limit-output -e procmon
在这种情况下，--limit-output（或 -r）限制输出为机器可读的分隔格式（我建议在PowerShell中解析时使用这种方式，而不是匹配“x package found”）。您可以类似以下方式做：
$Result = choco list --lo -r -e vscode | ConvertFrom-Csv -delimiter "|" -Header Id,Version
或者，只需检查包是否已安装：
if (choco list --lo -r -e procmon) {
Write-Host "'procmon' 已安装"
}
英文:
In both Chocolatey 1.* and 2.*, this should work:
choco list --lo --limit-output -e procmon
The --limit-output (or -r) in this case is restricting the output to a machine-readable delimited format (which I'd suggest using when parsing in PowerShell anyway, rather than matching on "x package found"). You could do something similar to the following:
$Result = choco list --lo -r -e vscode | ConvertFrom-Csv -delimiter "|" -Header Id,Version
Or, to just check that a package is installed:
if (choco list --lo -r -e procmon) {
Write-Host "'procmon' is installed"
}
