pdf2img在节点JS给人一种错误“标识”不被识别为一个内部或外部命令

var fs  = require('fs'); 
var pdf2img = require('pdf2img'); 

var input = __dirname+'\\public\\pdfs\\User.pdf'; 

pdf2img.setOptions({ 
    type: 'png',      // png or jpeg, default png 
    size: 1024,      // default 1024 
    density: 600,      // default 600 
    outputdir: __dirname+'\\public\\pdfs', // mandatory, outputdir must be absolute path 
    targetname: 'test'    // the prefix for the generated files, optional 
}); 

pdf2img.convert(input, function(err, info) { 
    if (err) console.log(err) 
    else console.log(info); 
});

运行此我得到以下错误后：pdf2img在节点JS给人一种错误“标识”不被识别为一个内部或外部命令

假设你有Ubuntu系统。您还必须为此库安装Dependency。运行以下命令：

sudo apt-get install graphicsmagick
