我是编程的初学者,所以至少我会遇到任何错误。这一天,编写了一些 Node.js 应用程序以将 Twitter 订阅源发布到 Discord,但没有这样做。
尽管我已经为 .env 文件提供了必要的数据,但我不知道为什么会看到此错误。已经运行了必要的依赖项,例如npm install gm、npm i dotenv。代码如下。
'use strict';
const fs = require('fs');
const commandExistsSync = require('command-exists').sync;
const logger = require('./bin/logger');
const { version } = require('./package.json');
logger.info(`Starting the twitter-to-discord application v${version}`);
// Extract all the env variables we will be using
const {
TWITTER_CONSUMER_KEYS,
TWITTER_CONSUMER_SECRET,
TWITTER_ACCESS_TOKEN_KEY,
TWITTER_ACCESS_TOKEN_SECRET,
MONGO_URI,
DISCORD_BOT_TOKEN,
DISCORD_CMD_PREFIX,
DISCORD_BOT_OWNER_ID,
TEMP,
} = process.env;
// Exit if the env variable was not set or passed. None can be empty
function envTest(value, name) {
logger.debug(`${name}=${value}`);
if (!value) {
logger.error(`Missing the environment variable '${name}'`);
process.exit(1);
}
}
envTest(TWITTER_CONSUMER_KEYS, 'TWITTER_CONSUMER_KEYS');
envTest(TWITTER_CONSUMER_SECRET, 'TWITTER_CONSUMER_SECRET');
envTest(TWITTER_ACCESS_TOKEN_KEY, 'TWITTER_ACCESS_TOKEN_KEY');
envTest(TWITTER_ACCESS_TOKEN_SECRET, 'TWITTER_ACCESS_TOKEN_SECRET');
envTest(MONGO_URI, 'MONGO_URI');
envTest(DISCORD_BOT_TOKEN, 'DISCORD_BOT_TOKEN');
envTest(DISCORD_CMD_PREFIX, 'DISCORD_CMD_PREFIX');
envTest(DISCORD_BOT_OWNER_ID, 'DISCORD_BOT_OWNER_ID');
envTest(TEMP, 'TEMP');
// Ensure we can access the temp directory
try {
fs.accessSync(process.env.TEMP, fs.constants.F_OK);
} catch (err) {
logger.error(`Unable to access the temp directory: ${process.env.TEMP}`);
logger.debug(err);
process.exit(1);
}
// Ensure all the commands we need to function exist via PATH
if (!commandExistsSync('ffmpeg')) {
logger.error('\'ffmpeg\' is not available on the command line');
process.exit(1);
}
if (!commandExistsSync('gm')) {
logger.error('\'gm\' is not available on the command line');
process.exit(1);
}
// Passed all the startup tests
// Continue to load application
require('./bin');
即使您已经安装了 dotenv,您也没有运行它。你应该require('dotenv').config()
在你的程序开始时有。
