如何将 /usr/bin/python 指向 python2.6？

我做过类似的事情：

我有点想撤消这一点。

尝试删除 virtualbox-ose 时出现错误提示

有一行字是这么说的/usr/bin/python 与 python 默认版本不匹配。必须将其重置为指向 python2.6

所以我的问题是如何让 /usr/bin/python 匹配默认版本 (python2.6)？

答案1

假设您有另一个版本[即 2.7] 并且还安装了 2.6，我会这样做：

ln -sf /usr/bin/python2.6 /usr/bin/python

然后，python 将成为 python2.6 的符号链接

这就是你要问的，对吧？或者我这里漏掉了什么。
