如何在不破坏我的系统的情况下设置Homebrew？

屈服于压力，我已经安装了Homebrew并给它一个旋转。但到目前为止，我对这次经历感到惊讶。我对Homebrew的印象是它是OS X易于使用，安全且独立的包管理器。但这不是我的经验。

（1）它做的第一件事就是在一些可怕的目录上改变一堆权限：

    ==> The following directories will be made group writable:
    /usr/local/.
    /usr/local/bin
    /usr/local/include
    /usr/local/lib
    /usr/local/lib/pkgconfig
    /usr/local/share
    /usr/local/share/man
    /usr/local/share/man/man1
    /usr/local/share/man/man3
    /usr/local/share/man/man7
    /usr/local/share/info
    /usr/local/share/doc
    ==> The following directories will have their group set to admin:
    /usr/local/.
    /usr/local/bin
    /usr/local/include
    /usr/local/lib
    /usr/local/lib/pkgconfig
    /usr/local/share
    /usr/local/share/man
    /usr/local/share/man/man1
    /usr/local/share/man/man3
    /usr/local/share/man/man7
    /usr/local/share/info
    /usr/local/share/doc

（2）它接下来要做的事情（按照建议的程序运行brew doctor）要求我删除一大堆可怕的文件：

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/de
    /usr/local/share/man/de/man1
    /usr/local/share/man/mann

Warning: Broken symlinks were found. Remove them with `brew prune`:
  /usr/local/share/ghostscript/9.05/Resource/Font/blex.pfb
  [hundreds...]

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:

（3）无法安装，例如，尝试安装matplotlib-basemap给我

==> Installing matplotlib-basemap from homebrew/homebrew-python
==> Installing dependencies for matplotlib-basemap: numpy, pkg-config, libpng, freetype, matplotlib, jpeg, libtiff, little-cms2, webp, pillow
==> Installing matplotlib-basemap dependency: numpy
==> Using Homebrew-provided fortran compiler.
This may be changed by setting the FC environment variable.
==> Downloading https://downloads.sourceforge.net/project/numpy/NumPy/1.9.1/numpy-1.9.1.tar.gz
Already downloaded: /Library/Caches/Homebrew/numpy-1.9.1.tar.gz
==> Patching
==> python setup.py build --fcompiler=gnu95 install --prefix=/usr/local/Cellar/numpy/1.9.1
  File "/private/tmp/numpy-PSE07t/numpy-1.9.1/numpy/distutils/fcompiler/gnu.py", line 197, in get_flags_opt
    v = self.get_version()
  File "/private/tmp/numpy-PSE07t/numpy-1.9.1/numpy/distutils/fcompiler/__init__.py", line 434, in get_version
    raise CompilerNotFound()
numpy.distutils.fcompiler.CompilerNotFound
couldn't understand kern.osversion `14.0.0'

即使我已经安装了ScyPy堆栈并且gfortran已经安装并正常工作。

有没有办法解决这个烂摊子？我如何从一个工作配置（site-packages中使用pip维护的Xcode，Python，Python包等）到一个也使用Homebrew（并继续工作）的配置？我是否真的需要遵循博士的所有建议并删除所有这些文件才能继续;这样做是否安全？

1 个答案:

答案 0 :(得分：1)

您展示的问题并不表示一般性问题。

  1. Homebrew“接管”/usr/local/的事实是一个记录完备的设计决策。起初它可能是“可怕的”，但它对每个人都有效。如果你真的想这样做，可以将Homebrew安装到不同的目录中。

    2. 如果您在brew doctor下安装了现有的非酿造软件，则

  2. /usr/local/警告也是正常的。请注意，这些警告说明了一些问题，如果您遇到问题，这些可能是原因。它没有说，在做任何其他事情之前删除所有这些文件。 （关于这个问题的SO有很多问题）

  3. 和4.只是运气不好AFAICT。这些都是有点偏僻的路径包，因此他们现在可能会遇到一些问题。

    4. 如果您可以安装主流软件包，我不知道，git或make或lynx，那么一切都很好，您只需要解决各个软件包的问题。
