无法缩小ionic项目

我试过了 cordova-uglify ( link )要缩小Ionic1项目,请在运行

ionic cordova build --release

我在中看到了我的js源代码 www 文件夹(共个) app-release-unsigned.apk 。。根本没有缩小。

ionic info 打印:

[WARN] Error with .\www\lib\ionic\version.json file: FILE_NOT_FOUND, trying
       .\bower.json.

cli packages: (C:\Program Files\nodejs\node_modules)

    @ionic/cli-utils  : 1.19.1

编辑:我跑步时注意到 ionic cordova build --release 我发现这些错误:

我没有 .\platforms\android\assets\www 文件夹

@Antonis这些是我尝试的步骤:

• 我删除了node\u模块并重新安装 npm install
• 我试过了 npm rebuild node-sass --force
• 删除并重新添加android平台 ionic cordova构建-发布
• 仍然获取错误 ENOENT: no such file or directory, scandir C:\nodejs\myproject\platforms\android\assets\www\js [...]

我如何生成 assets 文件夹 我看到有一个 资产 文件夹位于 .\platforms\android\app\src\main\assets 但是模块 离子缩小 寻找 .\platforms\android\assets
