Question

对不起，我的英语不好我想安装以下插件，但我不知道为什么会出错。

插件：

  http: ^0.12.0+2
  shared_preferences: ^0.5.3+1
  flutter_html_view: ^0.5.11

错误：

Running "flutter packages get" in alimelodi...                  
Because no versions of flutter_html_view match >0.5.11 <0.6.0 and flutter_html_view 0.5.11 depends on cached_network_image ^0.5.0+1, flutter_html_view ^0.5.11 requires cached_network_image ^0.5.0+1.
And because cached_network_image >=0.5.0+1 <0.6.0-alpha depends on flutter_cache_manager ^0.2.0+1, flutter_html_view ^0.5.11 requires flutter_cache_manager ^0.2.0+1.
Because flutter_cache_manager 0.2.0+1 depends on shared_preferences ^0.4.0 and no versions of flutter_cache_manager match >0.2.0+1 <0.3.0, flutter_cache_manager ^0.2.0+1 requires shared_preferences ^0.4.0.
Thus, flutter_html_view ^0.5.11 requires shared_preferences ^0.4.0.
So, because alimelodi depends on both flutter_html_view ^0.5.11 and shared_preferences ^0.5.3+1, version solving failed.

该错误很容易解释。 flutter_html_view中multiple times已报告了一个依赖项解决问题，维护人员应对其进行升级以解决该问题。

暂时，我建议您自己分叉并更新pubspec.yaml中的flutter_cache_manager，或者只使用已经做过的人替换它。例如：

flutter_html_view:
