Question

我是JavaScript和JSON的新手，我试图上传我的NPM包。出于某种原因，当我尝试发布它时出现此错误：

Unexpected token } in JSON at position 351 while parsing near '..."license": "ISC",

},
"bugs": {
"e..."

这是我的JSON文件。

{
"name": "M-P-Formulas-JS",
"version": "1.0.0",
"description": "The M-P-Formulas package for JavaScript. This package allows the user to use math and physics formulas such as the Pythagorean Theorem.",
"main": "mpformulasJS.js",
"author": {
    "email": "8b21espq@gmail.com",
    "name": "Jeff Lockhart",
    "url": "",
    "license": "ISC",
},
"bugs": {
    "email": "8b21espq@gmail.com",
},
"dependencies": {
    "Math": "",
},
"keywords": [
    "mpformulas",
    "mpformulasjs",
    "m-p-formulas-js",
    "math",
    "physics",
    "formulas",
    "module",
    "package",
 ],
}

我甚至跑npm cache clean但是，由于它不起作用，我可以保证我的代码是错误的。如果是这样，我该如何解决？

谢谢。

Answer 1

删除额外的逗号，因为它是关闭对象之前的最后一项。它导致无效的JSON。

"license": "ISC", // <--- Remove this comma

"bugs": {
    "email": "8b21espq@gmail.com", // <--- Remove this comma
}

JS对象和JSON是不同的。例如，这是一个有效的JS对象，但是无效的JSON：

bugs : {
    email : "8b21espq@gmail.com",
}

有效的JSON将是：

"bugs": {
    "email": "8b21espq@gmail.com"
}

Answer 2

删除结束括号和括号之前的逗号。仅使用逗号分隔元素。最后一个元素不应该有一个尾随逗号。一些解析器会让你逃脱这个，但它是无效的JavaScript和JSON。

 ],                                <-- Lose the comma.
}

您的JSON在对象的末尾有不需要的,。因此，请尝试使用以下代码删除每个对象的最后一项之后的,。

var xx={
"name": "M-P-Formulas-JS",
"version": "1.0.0",
"description": "The M-P-Formulas package for JavaScript. This package allows the user to use math and physics formulas such as the Pythagorean Theorem.",
"main": "mpformulasJS.js",
"author": {
    "email": "8b21espq@gmail.com",
    "name": "Jeff Lockhart",
    "url": "",
    "license": "ISC",
},
"bugs": {
    "email": "8b21espq@gmail.com",
},
"dependencies": {
    "Math": "",
},
"keywords": [
    "mpformulas",
    "mpformulasjs",
    "m-p-formulas-js",
    "math",
    "physics",
    "formulas",
    "module",
    "package",
 ],
}

var xxx=JSON.parse(JSON.stringify(xx).replace('",]','"]').replace('",}','"}'));
console.log(xxx);
