 function n(t) {
        return JSON.parse(a("5e5062e82f15fe4ca9d24bc561080e0e",atob(t),0,0,"012345677890123",1))

/home/shenjianlin/js/code.js:48
return JSON.parse(a("5e5062e82f15fe4ca9d24bc561080e0e",atob(t),0,0,"012345677890123",1))

sudo npm install btoa-atob
bin@1.0.0 /usr/bin
└── btoa-atob@0.1.2

                                                   ^

我已经安装了 atob 这个包了还是说我没有

btoa-atob 只是命令行工具，你应该安装的包是 atob, 并在代码中显示引入：

const atob = require('atob');
function n(t) {
    return JSON.parse(a("5e5062e82f15fe4ca9d24bc561080e0e",atob(t),0,0,"012345677890123",1))
}
