运行项目时出现构建错误

Question

我在窗口系统中创建了颤振项目。它在窗口中运行时出现任何错误。然后我在 ubuntu 上运行了相同的项目。我正面临某种找不到路径的错误。这些方法我都试过了。

1. 运行 : 'pub clean' 命令。
2. 运行：在此命令中发现 'flutter doctor' 0 问题
3. 创建了一个新项目并将所有lib文件夹放入ubuntu的新项目中，但仍然 我在控制台日志中遇到了这些错误。

代码编辑器 IntelliJ 中没有显示任何错误，我也在 Android Studio 上尝试过。我正在寻找过去 2-3 周的解决方案。但没有找到解决方案。这是控制台部分。

控制台日志：

Answer 1

问题在于它采用了您创建的 Windows 路径

我认为它可以解决您的问题..

在终端中打开项目文件夹路径并运行以下命令：

flutter clean

完成后，

运行此命令

flutter pub get

如果它不能解决您的问题，请在 ubuntu 中创建新项目并复制项目中的 lib 文件夹并在新项目中替换该 lib 文件夹。
