在 Visual Studio 代码中安装 brain.js 时出错
Error installing brain.js in Visual Studio Code
这里是新手。我最近切换到 Visual Studio 代码以与 Brain.js 一起使用，但是当我将它安装到终端（使用 NPM）时，出现错误。我尝试了多种其他解决方案，但 none 有效。任何帮助，将不胜感激。提前致谢=>
由于我也是 Linux 的新手，我尝试了一些安装命令的变体（如 sudo）并尝试在默认 Linux 终端上完成 Brain.js 安装但是无济于事 :( 。还有一件奇怪的事是我能够下载 BrainJS（较旧的库。）但不能 Brain.js
尽管我认为代码没有任何问题，但还是给了它。
const brain = require("brainjs");
let net = new brain.NeuralNetwork({ hiddenLayers: [3] }); //
Setting up neural network
const restaurants = { // Dataset
"KFC":"Monday",
"Item no.1":"Tuesday",
"Vaango":"Wednesday",
"Taco Bell":"Thursday",
"carls Jr.":"Friday",
"":"Saturday",
"Burger King":"Sunday"
}
const TrainingData = [];
for (let restaurantName in restaurants) {
const dayOfWeek = restaurants[restaurantName];
TrainingData.push({
input: { [dayOfWeek]: 1 },
output: { [restaurantName]: 1 }
});
}
const stats = net.train(TrainingData);
这是我收到的错误消息：
