Module not found: Error: Can't resolve 'cropbox'

问题

Environment:

Rails 6.0.2 Ruby 2.5.3

I installed cropperjs with yarn, Then I wanted to use cropper.js, but I got this error, It seems to be couldn't import cropbox module in fileUpload.js so, I changed the path, Sadly I couldn't import cropbox, would you like to help me?

app/javascript/packs/fileUpload.js:

import cropbox from 'cropbox' **#Here is problem **



 uppy.on('upload-success', (file, response) => {
// retrieve uploaded file data
const uploadedFileData = response.body['data']

// set hidden field value to the uploaded file data so that it's submitted
// with the form as the attachment
hiddenInput.value = JSON.stringify(uploadedFileData)

cropbox(imagePreview, response.uploadURL, {
  onCrop(detail) {
    let fileData = JSON.parse(hiddenInput.value)
    fileData['metadata']['crop'] = detail
    hiddenInput.value = JSON.stringify(fileData)
  }
})
})

before:

import cropbox from 'cropbox'

after1:

import cropbox from 'javascript/packs/cropbox'

after2:

import cropbox from 'app/javascript/packs/cropbox'
