I am having the same issue, Drupal 10.2.7, php 8.1.29, Apache 2.4.59 server, MySQL 8.0.37
I have loaded the echarts with:
composer remove --prefer-dist npm-asset/echarts
and verified that echarts exists in the libraries folder
I am not a composer expert but the echarts composer is looking for "apache/echarts", but my Drupal composer call it "npm-asset/echarts"
composer require 'drupal/charts_echarts:^1.0' --with-all-dependencies
returns this error:
- drupal/charts_echarts[1.0.0-alpha4, ..., 1.0.x-dev] require apache/echarts 5.3.2 -> could not be found in any version, there may be a typo in the package name.
Adam.bauer → created an issue.
I applied the patch in comment #2 with composer, Drupal Version 9.5.9, php version 8.1.18
upgrade status is happy, and the pages where bootstrap Paragraphs are use function as advertised.
I have to admit that I don't have an extensive use of this module in this site. This is a complex module and there certainly might be other implementations that don't fair so well.
