从 NodeJS 执行 PowerShell 脚本结果 "running scripts is disabled on this system"

Question

我正在尝试运行来自节点的 powershell 脚本。这是我当前的代码：

try {
    var spawn = require("child_process").spawn,child;
    child = spawn("powershell.exe", ['-file', "..\build.ps1", "-devmode"])
    child.stdout.on("data",function(data){
        //console.log("Powershell Data: " + data);
    });
    child.stderr.on("data",function(data){
        console.log("Powershell Errors: " + data);
    });
    child.on("exit",function(){
        console.log("Powershell Script finished");
    });
    child.stdin.end(); //end input
} catch (error) {
    console.error(error);
}

代码基于this question。当我运行它时，出现以下错误：

Powershell Errors: File C:\<path>\build.ps1 cannot be loaded because running scripts is disabled on this system. For more information,
see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.
    + CategoryInfo          : SecurityError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : UnauthorizedAccess

我试过设置执行策略Set-ExecutionPolicy -ExecutionPolicy Undefined -Scope LocalMachine，我也试过在调用脚本时绕过它，就像这样：

child = spawn("powershell.exe", ['-ExecutionPolicy ByPass', '-file', "..\build.ps1", "-devmode"])

这刚刚导致 The term '-ExecutionPolicy' is not recognized as the name of a cmdlet, function, script file, or operable program.

那么如何从节点执行这个脚本而不出现执行策略错误？

Answer 1

当您使用 Windows PowerShell CLI（powershell.exe) with the -File parameter to directly invoke a .ps1 script file, using the -ExecutionPolicy CLI parameter is indeed the only effective way to override the script-file execution policy 有效 临时，仅对于给定进程：-ExecutionPolicy Bypass 等同于从 PowerShell 会话内部调用
Set-ExecutionPolicy Bypass -Scope Process -Force。

但是，要从 spawn 调用执行此操作，每个参数 - 无论它代表参数 name 还是 value - 必须作为自己的数组元素传递:

spawn("powershell.exe", ['-ExecutionPolicy', 'ByPass', '-file', "..\build.ps1", "-devmode"])

至于你试过的：

在您的尝试中，spawn 必须在生成的命令行（在 Windows 上）的 "..." 中包含 '-ExecutionPolicy Bypass'，因为它包含空格。

当 powershell.exe 解析生成的命令行时，它不会将
"-ExecutionPolicy Bypass" 识别为试图通过 -ExecutionPolicy 带值的参数；事实上，它根本不将此参数识别为 CLI 参数，因此默认将其视为 PowerShell 源代码 - 即好像它已传递给默认 CLI 参数，-Command (-c).

也就是说，实际上您的尝试等同于从 PowerShell 会话内部提交 -ExecutionPolicy Bypass ... 作为命令，这会导致您看到的错误。
