【问题描述】：

我使用 brew 安装 jhipster，当前版本是 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到 4.14.4 并包含我在 4.14.3 上生成的代码。这是细节：

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

/usr/local/Cellar/jhipster/4.14.1 (9,066 files, 31.7MB)

.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",

    "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)

看来我应该删除一些目录，我该如何解决它

【问题讨论】：

为什么要编辑 .yo-rc.json 来更改版本并使用 --force？只需关注文档jhipster.tech/upgrading-an-application

标签： jhipster

【解决方案1】：

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

结果：

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