Question

我想知道如何在PowerShell中为开发Firefox扩展中使用的cmd执行set-alias：

cfx run -p C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\ripltbxm.cfxp

我已将以下内容添加到Microsoft.PowerShell_profile.ps1中：

Set-Alias cfxp cfx run -p "C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\ripltbxm.cfxp"

但是，当PowerShell启动时，它会显示错误：

Set-Alias : A positional parameter cannot be found that accepts argument 'run'.
At D:\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1:2 char:1
+ Set-Alias cfxp cfx run -p "C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profil ...

    + CategoryInfo          : InvalidArgument: (:) [Set-Alias], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.SetAliasCommand

也尝试过：

Set-Alias cfxp "cfx run -p C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\ripltbxm.cfxp"

另一个错误：

cfxp : The term 'cfx run -p C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\ripltbxm.cfxp' is not recognized
as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was
included, verify that the path is correct and try again.

在PowerShell中，只能为命令或cmdlet定义别名，而不能为包含参数的整个命令行定义别名：

NAME
    New-Alias

SYNOPSIS
    Creates a new alias.
[...]
DESCRIPTION
    The New-Alias cmdlet creates a new alias in the current Windows
    PowerShell session. Aliases created by using New-Alias are not
    saved after you exit the session or close Windows PowerShell. You
    can use the Export-Alias cmdlet to save your alias information to
    a file. You can later use Import-Alias to retrieve that saved
    alias information.

PARAMETERS
[...]
    -Value <String>
        Specifies the name of the cmdlet or command element that is
        being aliased.

如果您想要使用参数运行特定命令的简写，则需要自定义函数。

function cfxp {
  & cfx run -p "$env:APPDATA\Mozilla\Firefox\Profiles\ripltbxm.cfxp"
}

Firefox＆＃39; cfx的别名语法运行-profile <dir>＆＃39;
