Question

这是我的命令和输出（省略了一些命令行参数）。出了什么问题？谢谢。

$ brew reinstall pyqt --with-python3

Set PYTHONPATH if you want Python to find your site-packages:
  export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

  /usr/local/Cellar/pyqt/4.10.3: 560 files, 18M, built in 6.6 minutes

更新：我认为pyqt的公式以某种方式硬编码python的版本。例如，它明确包含python2.7/site-packages/之类的路径。这是文件的一部分：

  def install
    # On Mavericks we want to target libc++, this requires a non default qt makespec
    if ENV.compiler == :clang and MacOS.version >= :mavericks
      ENV.append "QMAKESPEC", "unsupported/macx-clang-libc++"
    end

    args = [ "--confirm-license",
             "--bindir=#{bin}",
             "--destdir=#{lib}/python2.7/site-packages",
             "--sipdir=#{share}/sip" ]
    # We need to run "configure.py" so that pyqtconfig.py is generated, which
    # is needed by PyQWT (and many other PyQt interoperable implementations such
    # as the ROS GUI libs). This file is currently needed for generating build
    # files appropriate for the qmake spec that was used to build Qt. This method
    # is deprecated and will be removed with SIP v5, so we do the actual compile
    # using the newer configure-ng.py as recommended.
    system "python", "configure.py", *args
    (lib/'python2.7/site-packages').install 'pyqtconfig.py'

    # On Mavericks we want to target libc++, this requires a non default qt makespec
    if ENV.compiler == :clang and MacOS.version >= :mavericks
      args << "--spec" << "unsupported/macx-clang-libc++"
    end

    system "python", "./configure-ng.py", *args
    system "make"
    system "make", "install"
  end

你应该在Homebrew的git上查看这个问题： https://github.com/Homebrew/homebrew/issues/25735

我们不能再使用带有pyside / pyqt / sip的--with-python3参数。不幸的是，似乎我们暂时不能将Homebrew用于这些模块。他们可能必须找到另一个处理公式的解决方案，以便首先安装Python 2.7和Python3。

我摸不着头几天搞清楚了。最后从源代码安装PyQt。

祝你好运。

通过带有`--with-python3`的自制软件安装pyqt，但仍然转到Python 2
