1.安装Ghost.py出现问题：在安装pyside前提下安装
2.brew安装pyside
Error: The `brew link` step did not complete successfully The formula built, but is not symlinked into /usr/local Could not symlink lib/pkgconfig/QtCLucene.pc /usr/local/lib/pkgconfig is not writable.
按照提示：
You can try again using: brew link qt
再次操作：
brew link qt Linking /usr/local/Cellar/qt/4.8.7_2... Error: Could not symlink lib/pkgconfig/QtCLucene.pc /usr/local/lib/pkgconfig is not writable.
出现以上错误，我们使用brew doctor查看问题详情，以及建议操作：
Warning: /usr/local/lib/pkgconfig isn‘t writable. This can happen if you "sudo make install" software that isn‘t managed by Homebrew. If a formula tries to write a file to this directory, the install will fail during the link step. You should probably change the ownership and permissions of /usr/local/lib/pkgconfig back to your user account. sudo chown -R $(whoami) /usr/local/lib/pkgconfig
