Question

通过以下方式加载开发人员工具时：

**********************************************************************
** Visual Studio 2017 Developer Command Prompt v15.9.7
** Copyright (c) 2017 Microsoft Corporation
**********************************************************************
[vcvarsall.bat] Environment initialized for: 'x64'

然后我尝试通过以下方式为CMD中的C ++ hello world应用程序生成构建文件：

var STUD = [{"id":1,"name":"Kida"},{"id":2,"name":"Kidb"},{"id":3,"name":"Kidc"},{"id":4,"name":"Kidd"},{"id":5,"name":"Kide"}];
var IDCRD = [{"id":3,"status":"Y"},{"id":4,"status":"Y"},{"id":2,"status":"N"},{"id":5,"status":"Y"},{"id":1,"status":"N"}];

function status(i){ return IDCRD.filter(w => w.id == STUD[i].id)[0].status }

console.log(status(0));
console.log(status(1));
console.log(status(2));
console.log(status(3));
console.log(status(4));

我得到：

CMake Error: Could not create named generator 'NMake

# etc.

但是如果我通过在CMD中编写status = i => IDCRD.filter(w => w.id == STUD[i].id)[0].status切换到PowerShell并运行相同的命令：

cmake -G 'NMake Makefiles'

它正常工作：

-- The C compiler identification is MSVC 19.16.27027.1
-- The CXX compiler identification is MSVC 19.16.27027.1

# etc.

您知道为什么powershell在PowerShell中不能在CMD中工作吗？

Answer 1

Windows命令提示符无法将单引号识别为引号字符。您必须使用双引号代替。

更改

cmake -G 'NMake Makefiles'

到

cmake -G "NMake Makefiles"

问题将消失。

为什么生成“ NMake Makefiles”时，cmake在powershell和命令行中的行为有所不同？
