不能在Windows的NPM脚本中使用mkdir

Question

我正在尝试使用如下所示的脚本:

{
    "scripts":
        "setup": "mkdir -p ./my-dir"
}

它失败了,至少在Windows上,即使我从Git Bash提示符运行它也是如此.即使尝试只是mkdir ./my-dir不起作用.我无法弄清楚它应该失败的原因.

它给出的错误是"语法不正确"错误:

> my-app@0.0.1 stage C:\my-app
> mkdir ./my-dir

The syntax of the command is incorrect.

如果这不起作用,是否有一种跨平台友好的方式来初始化一个空目录？

Answer 1

您可以使用NPX 加 mkdirp对于没有安装全球比较轻巧，便携的解决方案

将此添加到package.json：

"scripts": {
  "create-dir": "npx mkdirp _site/assets",
}

然后像这样使用：

$ npm run create-dir

该模块可能会解决您的问题:https: //www.npmjs.com/package/mkdirp

Answer 3

Npm 使用的是 windows mkdir 命令，而不是 linux。用

"setup": "mkdir .\\my-dir"

使用反斜杠。

您还可以安装 cygwin 并运行：

/cygwin64/bin/mkdir -p mydir
