Answer 1

将const express = require('express'); const path = require('path'); const bodyParser = require('body-parser'); const cors = require('cors'); const app = express(); app.use(cors()); // some route controllers const customRoute = require('./customRoute.controller'); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: true })); // Custom routes app.use('/api/tags', customRoute); app.use(express.static(path.join(__dirname, 'dist'))); // Catch all other routes & return index file app.get('*', (req, res) => { res.sendFile(path.join(__dirname, 'dist/index.html')); }); module.exports = app; 添加到您的项目存储库中。

  

2.1.0-alpha05房间取决于kotlinx-metadata-jvm工件，该工件当前在Maven Central中不可用

Answer 2

我摆脱了将gradle build插件升级到3.3.2的错误：

dependencies {
    classpath 'com.android.tools.build:gradle:3.3.2'
    classpath 'com.google.gms:google-services:4.2.0'
    classpath 'io.fabric.tools:gradle:1.27.1'
}

如果您一直使用io.fabric插件，该版本将产生一些警告（请参见API 'variant.getExternalNativeBuildTasks()' is obsolete and has been replaced with 'variant.getExternalNativeBuildProviders()）。

嘿，我遇到了类似的问题，这是显示的错误：

Required by:
    project :app > androidx.room:room-compiler:2.1.0-alpha05

我发现的临时解决方案是将room_version降级为

 def room_version = "2.1.0-alpha04"

请分享是否有更好的解决方案
