因为 examplecode 依赖于audioplayers ^0.16.2，而audioplayers ^0.16.2又依赖于path_provider ^1.6.22，所以需要path_provider ^1.6.22

Question

你好朋友，我现在在应用程序中使用路径提供程序插件，我也想添加音频播放器插件，当我尝试在我的应用程序中安装音频包时，它显示此错误，请帮助我，如果使用路径提供程序，为什么无法在我的应用程序中安装音频包包路径提供商对音频插件有任何问题吗？

Because examplecode depends on audioplayers ^0.16.2 which depends on path_provider ^1.6.22, path_provider ^1.6.22 is required.
So, because examplecode depends on path_provider ^0.4.1, version solving failed.
pub get failed (1; So, because examplecode depends on path_provider ^0.4.1, version solving failed.)

这是我的包裹

Answer 1

但你的答案实际上并不是这样做的方法。

这个问题一般是包冲突的问题。对于任何彼此不兼容的软件包解决这个问题很简单

1. 在 pubspec.yaml 中，不要为那些冲突的包编写版本号，而是用“any”替换版本。

EG 代替

 audioplayers: ^0.13.6

写这个：

 audioplayers: any

2. 而不是在终端中运行“flutter pub get”。

3. 问题应该得到解决，但是不要把它们留在“任何”上，这是非常糟糕的做法。因此，转到 pubspec.lock 文件并查找这些包，您将看到 flutter 已自动为它们选择版本，并且这些版本是 flutter 发现它们都兼容的版本。获取这些版本并将“任何”版本替换回 pub 给出的新版本号。
