flutter - 因为示例代码依赖于 audioplayers ^0.16.2 而依赖于 path_provider ^1.6.22，所以需要 path_provider ^1.6.22

Question

你好 friend 我现在在应用程序中使用路径提供程序插件我也想在我尝试在我的应用程序中安装音频包时添加音频播放器插件它向我显示此错误请帮助我什么问题为什么无法在我的应用程序中安装音频包如果使用的路径提供程序包路径提供程序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

但您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。对于任何相互不兼容的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，而是将版本替换为“任何”。

E.G而不是

 audioplayers: ^0.13.6

这样写:

 audioplayers: any

1. 然后在终端中运行“flutter pub get”。

2. 问题应该得到解决，但是不要让它们停留在“任何”状态，那是非常糟糕的做法。所以去你的 pubspec.lock 文件并寻找那些包，你会看到 flutter 已经自动为它们选择了版本，而这些版本是 flutter 发现它们兼容的版本。获取这些版本并将“任何”版本替换回 pub 给出的新版本号。
