brew doctor：警告：在 /usr/local/lib 中发现了未安装的 dylibs。

Question

运行

brew doctor

会给我这个：

警告：在 /usr/local/lib 中发现了未经过酿造的 dylibs。如果您没有有意将它们放在那里，则在构建 Homebrew 公式时可能会导致问题，并且可能需要删除。

未预期的 dylibs：

/usr/local/lib/libqmi_api.dylib

/usr/local/lib/libvousb.dylib

有人知道这些 dylibs 是什么吗？

我认为它们与我很久以前安装的旧VodaPhone 3G调制解调器驱动程序有关... 我刚刚将它们移除，但如果有人确定，请一定要让我知道-干杯！ :) - tbarbe

就我所知，我也曾遇到这个问题，实际上是 Vodafone 的库引起的。 - Greg Gauthier

Answer 1

如果您仍然需要这些库，我建议您尝试升级它们。我曾经遇到过与libusb类似的问题，后来通过进行“brew upgrade”解决了该问题。

brew upgrade libqmi_api
brew upgrade libvousb

有时候，brew 无法将库符号链接到 /usr/local 中。这种情况发生在您已经拥有旧版本的库的符号链接时。

brew link --overwrite libusb

应该做这件事。

这是我的测试用例，使用 libusb 库：

$ brew doctor
Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected dylibs:
    /usr/local/lib/libusb-1.0.0.dylib

$ brew upgrade libusb

Possible conflicting files are:
/usr/local/lib/libusb-1.0.0.dylib
==> Summary

$ brew link --overwrite libusb

$ brew doctor
Your system is ready to brew.

希望这可以帮到您。
