'npm run dev'命令不适用于带有bash错误的Windows

Question

我正在尝试创建一个laravel nova工具。我正在运行此命令。

npm run dev

但是我没有编译，而是遇到了这个错误。

> @ dev C:\wamp64\www\project
> npm run development

npm ERR! file bash 
npm ERR! path bash 
npm ERR! code ELIFECYCLE 
npm ERR! errno ENOENT 
npm ERR! syscall spawn bash 
npm ERR! @ dev: `npm run development` 
npm ERR! spawn bash ENOENT 
npm ERR! 
npm ERR! Failed at the @ dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in: 
npm ERR!     C:\Users\Name\AppData\Roaming\npm-cache\_logs\2019-04-03T13_41_19_035Z-debug.log

C:\wamp64\www\project>

如果有人知道如何解决这个问题，那将是很大的帮助。

这是我的错误日志文件，

按照指示，我从此link下载了bash，并按说明将复制的bash.exe解压缩到 C：\ Users \ Name \ AppData \ Roaming \ npm 。现在出现此错误，

Answer 1

您的系统不知道bash。

这是因为未安装或不在%PATH%中，或者%PATH对npm（环境）不可用。当您访问具有全局性但实际上仅在特定项目路径中可用的脚本时，也会发生这种情况。

首先请确保已安装适当的二进制文件，然后尝试使用绝对路径。

很可能是因为您在 Windows 上，所以没有安装bash或npm不知道它在哪里。

Answer 2

我在Windows 10上遇到了这个问题。 $ npm运行开始

所有错误都由此得到解决：

$ npm install --save-dev babel-loader babel-core

.babelrc file { "presets": ["@babel/preset-env"] }
