javascript - "EMALFORMED Failed to read bower.json"上 "bower install requirejs-text"

Question

当我尝试安装requirejs-text时，我收到一个我不明白的错误。

$ bower install requirejs-text
bower                       EMALFORMED Failed to read /Users/bgolder/projects/explorer/front/bower.json

Additional error details:
Unexpected string

在 Bower.json 中，我看不出有什么问题。

{
  "name": "front",
  "version": "0.0.0",
  "dependencies": {
    "bootstrap": "~3.1.1"
    "jquery": "~1.10.2",
    "requirejs": "~2.1.9",
    "requirejs-text": "~2.0.10",
    "underscore": "~1.5.2",
    "backbone": "~1.1.0",
    "modernizr": "~2.6.2"
  },
  "devDependencies": {},
}

如果我在 Bower 上使用详细选项，我会得到此跟踪。

这仍然不能解释问题所在。

Answer 1

您的 JSON 文件中有两个语法错误。第一个错误是 "bootstrap": "~3.1.1" 之后缺少 ,。这就是您收到错误消息的原因。下一行的 "jquery" 字符串不是预期的。我通过肉眼检查你的文件发现了这个错误。在 JavaScript 或 JSON 编辑器中加载它也会显示它。

第二个错误是 {} 后面的逗号。 JavaScript 解析器不会有问题，但 JSON 解析器会出现问题。我认为 JSON 编辑器会揭示这个问题。我根据收到的新错误消息以及反复试验发现了它。

这是固定文件:

{
  "name": "front",
  "version": "0.0.0",
  "dependencies": {
    "bootstrap": "~3.1.1",
    "jquery": "~1.10.2",
    "requirejs": "~2.1.9",
    "requirejs-text": "~2.0.10",
    "underscore": "~1.5.2",
    "backbone": "~1.1.0",
    "modernizr": "~2.6.2"
  },
  "devDependencies": {}
}
