Macports select default Python interpreter for executing scripts?
提问by goh
I used python_select, it seems like it does not change the default python for executing scripts, for instance django-admin.py runserver(without python in front).
我使用过python_select，它似乎不会更改执行脚本的默认 python，例如django-admin.py runserver（前面没有 python）。
How do i change this?
我如何改变这个？

There is /usr/bin/python, which is usually earlier in the path (has a higher precedence) than MacPort's binary folder (/opt/local/bin/python). The python_selectscript changes only /opt/local/bin/python, so you have to make sure there is no other pythonbinary on your path taking precedence over it.
有/usr/bin/python，通常在路径中比 MacPort 的二进制文件夹 ( /opt/local/bin/python)更早（具有更高的优先级）。该python_select脚本只改变/opt/local/bin/python肯定是没有的，所以你必须让python你的路径优先于它的二进制文件。
Solution (as root):
解决方案（以 root 身份）：
mv /usr/bin/python /usr/bin/python.orig
ln -s /opt/local/bin/python /usr/bin/python
port select --set python python26
Make sure you replace python26in the third line with your intended Python version.
确保python26将第三行中的内容替换为您想要的 Python 版本。
It worked for me a few days ago with MacPort 2.0.0. If you have an older MacPorts library, then you should either upgrade it or use python_selectinstead of port select --set python.
几天前它在 MacPort 2.0.0 上对我有用。如果你有一个旧的MacPorts库，那么你应该升级，或使用python_select替代port select --set python。
