Homebrew用python模块安装libxml2

Question

早上好,

我正在尝试使用python模块安装libxml2.我尝试过以下方法:

brew install --with-python libxml2                                                                  
==> Downloading ftp://xmlsoft.org/libxml2/libxml2-2.8.0.tar.gz
Already downloaded: /Users/brandon/Library/Caches/Homebrew/libxml2-2.8.0.tar.gz
==> ./configure --prefix=/usr/local/Cellar/libxml2/2.8.0 --without-python

正如你所看到的......即使使用--with-python标志,它仍然在没有python的情况下配置源代码!

在安装结束时,自制软件说:

Generally there are no consequences of this for you.
If you build your own software and it requires this formula, you'll need
to add its lib & include paths to your build variables:

    LDFLAGS  -L/usr/local/Cellar/libxml2/2.8.0/lib
    CPPFLAGS -I/usr/local/Cellar/libxml2/2.8.0/include

当我尝试安装gnome-doc-utils包时:

Gnome-doc-utils requires libxml2 to be compiled
with the python modules enabled, to do so:
  $ brew install libxml2 --with-python

显然我再试一次......

?? brew install libxml2 --with-python
Error: libxml2-2.8.0 already installed

我还是新手......所以任何帮助都会非常感激.

Answer 1

首先,您无法安装libxml2,因为您已成功安装它,因此您首先需要将其卸载.

brew uninstall libxml2

接下来,您需要编辑brew配方 - 这很简单 -

输入 brew edit libxml2并更改该行

system "./configure", "--prefix=#{prefix}", "--without-python"

对此:

system "./configure", "--prefix=#{prefix}", "--with-python"

这并没有解决brew公式的问题,但它确实强制标志"--with-python",所以下次你输入brew install libxml2它时会安装python库.

如果您需要重置公式(撤消更改),只需键入即可 brew update

Answer 2

这对我有用.如果先前完成,首先取消链接/卸载:

brew unlink libxml2
brew unlink libxslt
brew uninstall libxml2
brew uninstall libxslt

然后

brew install --framework python
brew install --with-python libxml2
brew install --with-python libxslt
brew link libxml2 --force
brew link libxslt --force

瞧!
