ruby-on-rails - 运行 Brew Doctor 时的主要警告

Question

我跑了 brew doctor并收到一些警告消息，我想我知道要采取什么措施来修复，但想看看我是否在正确的 rails 上。以下是我收到的警告列表:

Warning: /usr/local/lib/pkgconfig isn't writable.

This can happen if you "sudo make install" software that isn't managed by
by Homebrew. If a formula tries to write a file to this directory, the
install will fail during the link step.

You should probably `chown` /usr/local/lib/pkgconfig

Warning: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:

    /usr/local/share/man/mann

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/libtcl8.6.dylib
    /usr/local/lib/libtk8.6.dylib

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

Unexpected .pc files:
    /usr/local/lib/pkgconfig/tcl.pc
    /usr/local/lib/pkgconfig/tk.pc

Warning: Unbrewed static libraries 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 static libraries:
    /usr/local/lib/libtclstub8.6.a
    /usr/local/lib/libtkstub8.6.a

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:

    libyaml

对于第一种情况，我应该运行 chown <user>/usr/local/lib/pkgconfig 吗？

Warning: /usr/local/lib/pkgconfig isn't writable.

    This can happen if you "sudo make install" software that isn't managed by
    by Homebrew. If a formula tries to write a file to this directory, the
    install will fail during the link step.

    You should probably `chown` /usr/local/lib/pkgconfig

然后chown <user>/usr/local/share/man/mann下一条消息

Warning: Some directories in /usr/local/share/man aren't writable.

    directories, then the install will fail during the link step.

        /usr/local/share/man/mann

不确定如何处理这些关于删除文件的警告。 (？？？)

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/libtcl8.6.dylib
        /usr/local/lib/libtk8.6.dylib

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

    Unexpected .pc files:
        /usr/local/lib/pkgconfig/tcl.pc
        /usr/local/lib/pkgconfig/tk.pc

    Unexpected static libraries:
        /usr/local/lib/libtclstub8.6.a
        /usr/local/lib/libtkstub8.6.a

最后运行brew link libyaml ？

Warning: You have unlinked kegs in your Cellar
    Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
    those kegs to fail to run properly once built. Run `brew link` on these:

        libyaml

Answer 1

要解决权限问题，您可以chown -R your_username/usr/local 递归更改/usr/local 下所有内容的所有权。

你应该brew link libyaml。

关于 dylibs 的警告告诉你你有一个 Tcl/Tk 库安装到/usr/local。如果您知道它是如何到达那里并且知道您不需要它，则可以将其卸载。如果您不知道它是如何到达那里的，您可以重命名它的文件，这样构建就不会拾取它(如果您发现某些东西依赖于它们，您可以将它们放回去)。除非并且直到某些东西以与 Tk 相关的方式损坏，否则将它留在原地可能没问题；它可能永远不会给您带来麻烦。
