执行ionic capacitor sync android时如何添加npm install --force参数？

执行命令：

ionic capacitor sync android

过程中自动运行npm.cmd i -E @capacitor/android@3.1.1，出现以下依赖冲突错误：

C:\Users\DELL\Documents\inspecciones\inpecciones-app>ionic capacitor sync android
> npm.cmd i -E @capacitor/android@3.1.1

解决方法 #

要让ionic capacitor sync android执行npm install时带上--force参数，可采用以下两种方式：

• 方式一：手动前置执行npm install
  先单独运行带--force的npm安装命令，再执行sync：

npm i -E @capacitor/android@3.1.1 --force
ionic capacitor sync android

• 方式二：临时设置npm配置
  通过环境变量让npm默认启用force模式，再执行sync命令：
  • Windows cmd：

    set npm_config_force=true
    ionic capacitor sync android
    

  • Windows PowerShell：

    $env:npm_config_force = "true"
    ionic capacitor sync android
