jhipster更新——对现有项目的强制

我使用brew安装jhipster，当前版本为4.14.4。我已经生成了一个4.14.3版本的项目。如何将现有项目更新为4.14.4并包含我在4.14.3中生成的代码。详情如下:

brew info jhipster
jhipster: stable 4.14.4 (bottled)
Generate, develop and deploy Spring Boot + Angular applications

.yo-rc.json文件是：

{
  "generator-jhipster": {
    "promptValues": {
      "packageName": "com.sgcc.syn",
      "nativeLanguage": "zh-cn"
    },
    "jhipsterVersion": "4.14.3",
    "baseName": "pmt",
    "packageName": "com.sgcc.syn",
    "packageFolder": "com/sgcc/syn",
    "serverPort": "8080",
    "authenticationType": "jwt",
    "cacheProvider": "ehcache",
    "enableHibernateCache": true,
    "websocket": false,
    "databaseType": "sql",
    "devDatabaseType": "h2Disk",
    "prodDatabaseType": "mysql",
    "searchEngine": false,
    "messageBroker": "kafka",

    "enableSwaggerCodegen": false,
    "jwtSecretKey": "4166646bfabd18ccec24a2d10d5b15229ba3fae4",
    "clientFramework": "angularX",
    "useSass": false,
    "clientPackageManager": "yarn",
    "applicationType": "monolith",
    "testFrameworks": [
      "gatling"
    ],
    "jhiPrefix": "jhi",
    "enableTranslation": true,
    "nativeLanguage": "zh-cn",
    "languages": [
      "zh-cn"
    ]
  }
}

我将“jhipsterVersion”：“4.14.3”更改为4.14.4，并更新项目：

jhipster upgrade
Using JHipster version installed globally
Executing jhipster:upgrade
Options:
Welcome to the JHipster Upgrade Sub-Generator
This will upgrade your current application codebase to the latest JHipster version
Looking for latest generator-jhipster version...
yarn info v1.6.0
4.14.4
Done in 0.29s.
events.js:182
      throw er; // Unhandled 'error' event
      ^

Error: ERROR! No update available. Application has already been generated with latest version.

    at Socket.stream.socket.on (internal/child_process.js:348:11)
    at emitOne (events.js:115:13)

似乎我应该删除一些目录，我如何才能解决它

rm -rf node_modules
rm yarn.lock

jhipster
overrite package.json  //choose yes
the remainder conflict file i choose y or n on my demaind

因此：

jhipster --version
Using JHipster version installed locally in current project's node_modules
4.14.4

为什么要编辑.yo-rc.json来更改版本并使用--force？跟着医生走就行了
