为什么希罗库找不到时机？

Question

我正在创建一个discordbot并将其托管在heroku上。我安装了moment.js库，但它找不到它，给出了以下错误

2022-03-27T12:41:48.954612+00:00 app[worker.1]: Error: Cannot find module 'moment'

我的代码

const moment = require('moment');

我该怎么办？

package.json:

{
"name": "freaksland-bot",
"version": "1.0.0",
"description": "",
"main": "bot.js",
"scripts": {
"test": "echo "Error: no test specified" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"@discordjs/voice": "^0.8.0",
"moment.js": "^2.29.1",
"discord.js": "^13.6.0",
"init": "^0.1.2"
}
}

Answer 1

您依赖于moment.js，但正确的包只是moment。

您是否手动将其添加到package.json？首先，拆下那条线。

然后添加正确的包：

• 如果使用的是Yarn，请运行yarn add moment
• 如果使用的是NPM，请运行npm install moment

这应该在本地安装依赖项，并将其添加到package.json和相关的锁定文件中。提交对这些文件的更改并重新部署。
