如何在Rust中克服以下GTK4构建错误

Question

我已经下载了GTK4演示，并将其放在一个目录中。我已经在VC中打开了它，并尝试按照Read.ME运行演示。

有什么办法解决这个问题吗？

Answer 1

答案是另一个使用GTK的应用程序在路径上比我的Rust编译器条目高。当我把它移到编译的应用程序时。

Answer 2

这个问题是从错误信息中提出来的，但对我来说却是另一个原因。对我来说是用Linuxbrew。我完全卸载了它，https://docs.brew.sh/FAQ#:~:text=How%20do%20I%20uninstall%20Homebrew,from%20the%20Homebrew%2Finstall%20repository。
