PowerShell 7 - how to run a command on windows?
问题
我只想从PowerShell 7脚本中使用参数运行docker命令。当我只使用以下命令时，它可以正常工作：
if ($isRunning -eq $false) {
docker run -it --rm -p 8080:8080 -v <some_path> <image_name>
}
但我需要在此命令中使用变量，所以我将它更改为：
& "docker run -it --rm -p 8080:8080 -v $script:myPath\:/usr/local/whatever"
它可以运行，但然后告诉我“未将术语'docker run -it ...'识别为cmdlet的名称...”。看起来PowerShell脚本与cmd不具有相同的$PATH环境变量值。
这里有什么问题？

I just want to run a docker command with parameters from PowerShell 7 script. When I just use the command:
if ($isRunning -eq $false) {
docker run -it --rm -p 8080:8080 -v <some_path> <image_name>
}
it works. But I need to use a variable in this command, so I changed it to:
& "docker run -it --rm -p 8080:8080 -v $script:myPath\:/usr/local/whatever"
And it runs but then it tells me The term 'docker run -it ...' is not recognized as a name of a cmdlet.... It seems like PowerShell script does not have the same $PATH environment variable value as cmd.
What's wrong here?

以下可能有效，将参数作为参数数组传递给您的 docker 命令，而不是嵌入在字符串中的表达式，目前失败是因为 PowerShell 正试图查找整个表达式的命令（docker run -it ...）。
if (-not $isRunning) {
docker @(
'run'
'-it'
'--rm'
'-p'
'8080:8080'
'-v'
"$script:myPath:/usr/local/whatever"
)
}
英文:
The following might work, passing the arguments to your docker command as an array of arguments instead of embedding all the expression in a string which is currently failing because PowerShell is trying to find a command with the name of the entire expression (docker run -it ...).
if (-not $isRunning) {
docker @(
'run'
'-it'
'--rm'
'-p'
'8080:8080'
'-v'
"$script:myPath\:/usr/local/whatever"
)
}
