将我的项目上传到 Heroku 时出现此错误。 我正在使用 MapBox 和 node.js

Question

嗨，在 Heroku 上上传我的应用程序时，我收到以下错误 - “throw new Error('Cannot create a client without an access token');”

const mbxGeocoding = require('@mapbox/mapbox-sdk/services/geocoding');
const geocodingClient = mbxGeocoding({ accessToken: process.env.MAPBOX_TOKEN });

这就是我通过 process.env.MAPBOX_TOKEN 使用 Mapbox 令牌的方式

确保在 .env 文件中声明 mapbox 令牌时没有空格

错误的：

MAPBOX_TOKEN = ckzsjnzvkqsd,mvlqdf,;ev^q;v

正确的：

MAPBOX_TOKEN=ckzsjnzvkqsd,mvlqdf,;ev^q;v
