jhipster 5.0.1 升级后 yarn 启动失败

Question

我已经生成了一个 JHipster / React 应用程序，并且在将 JHipster 升级到 5.0.1（从 5.0.0-beta.1）和运行ning jhipster upgrade, 当我运行 yarn start:

时得到以下信息

WARNING in configuration
The 'mode' option has not been set, webpack will fallback to 'production' for this value. Set 'mode' option to 'development' or 'production' to enable defaults for each environment.
You can also set it to 'none' to disable any default behavior. Learn more: https://webpack.js.org/concepts/mode/

ERROR in multi (webpack)-dev-server/client?http://localhost:8081 ./src
Module not found: Error: Can't resolve './src' in '/Users/yvon/git/ods-jhipster-sns'
 @ multi (webpack)-dev-server/client?http://localhost:8081 ./src
ℹ ｢wdm｣: Failed to compile.

我尝试使用 5.0.1 生成器生成一个新的 jhipster 应用程序分支，但是 yarn start 在完全相同的位置失败。

这是package.json的相关部分：

  "scripts": {
"precommit": "lint-staged",
"prettier:format": "yarn prettier --write 'src/**/*.{ts,tsx,css,scss}'",
"lint": "tslint --project tsconfig.json -e 'node_modules/**'",
"lint:fix": "yarn run lint --fix",
"cleanup": "rimraf target/www",
"start": "yarn run webpack:dev",
"test": "yarn run lint && jest --coverage --logHeapUsage -w=2 --config src/test/javascript/jest.conf.js",
"test:watch": "yarn test --watch",
"webpack:dev": "yarn run webpack-dev-server --config webpack/webpack.dev.js --progress --inline --profile --port=9060",
"webpack:build:main": "yarn run webpack --config webpack/webpack.dev.js --progress --profile",
"webpack:build": "yarn run cleanup && yarn run webpack:build:main",
"webpack:prod:main": "yarn run webpack --config webpack/webpack.prod.js --profile",
"webpack:prod": "yarn run cleanup && yarn run webpack:prod:main",
"webpack:test": "yarn run test",
"webpack-dev-server": "node --max_old_space_size=4096 node_modules/webpack-dev-server/bin/webpack-dev-server.js",
"webpack": "node --max_old_space_size=4096 node_modules/webpack/bin/webpack.js"},

和webpack-dev.js:

const webpack = require('webpack');
const writeFilePlugin = require('write-file-webpack-plugin');
const webpackMerge = require('webpack-merge');
const BrowserSyncPlugin = require('browser-sync-webpack-plugin');
const WebpackNotifierPlugin = require('webpack-notifier');
const path = require('path');

const utils = require('./utils.js');
const commonConfig = require('./webpack.common.js');

const ENV = 'development';

module.exports = webpackMerge(commonConfig({ env: ENV }), {
  devtool: 'cheap-module-source-map', // https://reactjs.org/docs/cross-origin-errors.html
  mode: 'development',
  entry: [
    'react-hot-loader/patch',
    './src/main/webapp/app/index'
  ],

JHipster/React 5.0.1 损坏了吗，还是我遗漏了一些明显的东西？

我遇到了同样的问题。使用 jhipster info 命令我发现 yarn 的版本太旧了。我升级到1.7版。现在 Webpack 服务器是运行.
