387：ruby json解析错误的意外令牌

Question

我试图在Ruby中解析JSON数组并得到以下错误：

ERROR: 387: unexpected token at '{"A"=>"a1", "B"=>"01", "wc"=>"b1"}, {"A"=>"a2", "B"=>"0", "C"=>"b2"}]'

正在解析的JSON是：

{
    "node": [{
        "A": "a1",
        "B": "01",
        "C": "b1"
    }, {
        "A": "a2",
        "B": "0",
        "C": "b2"
    }]
}
