在 Mac Ports 中添加变体
我想知道如果您已经安装了端口，如何将变体附加到端口。例如，我安装了“vim”端口，并想返回并添加 python25 变体。我需要删除vim并重新安装吗？这只是一个例子，我真的很想知道为任何端口执行此操作的过程。
感谢您的帮助， 格雷格
I was wondering how you can append a variant to a port if you have already installed the port. For example I installed the 'vim' port and would like to go back and add the python25 variant. Do I need to delete vim and reinstall it? This is just an example, I would really like to know the process to do this for any port.
Thanks for any help,
Greg

任何时候只能激活
MacPorts端口的一种变体。但是，在 MacPorts 术语中，可以同时安装端口的多个变体和/或版本。其中，至多有一个是活跃，任何其他都是非活跃。如果您偶尔需要在变体之间切换，您可以根据需要激活特定变体。这也将自动停用任何冲突的活动端口。例如，这是一个假设的vim示例（未经过充分测试！）：Only one variant of a
MacPortsport can be active at any one time. However, inMacPortsterminology, multiple variants and/or versions of a port can beinstalledsimultaneously. Of those, at most one isactive, any others areinactive. If you need to occasionally alternate between variants, you can activate a specific variant as needed. That will also automatically deactivate any conflicting active port. For example, here's a hypotheticalvimexample (not fully tested!):我相信 macports 现在通过
--enforce-variants选项原生支持这一点。所以在上面的例子中，命令是I believe macports supports this natively now with the
--enforce-variantsoption. So in the above case, the command would be您确实需要重新安装。之后没有办法添加变体——这样做甚至没有意义。变体会影响构建过程中的设置。
You do need to reinstall. There's no way to add a variant on afterwards – nor does it even make sense to do so. Variants affect settings during the build process.
