推荐答案

根据您的发行版及其版本，您无法更改系统的默认python版本而不会破坏系统。如果您已安装Python 2.7，则其解释器可能位于 python2.7 的路径上。

Depending on your distribution and its version you cannot change the default python version of the system without breaking the system. If you have Python 2.7 installed then its interpreter is probably on your path as python2.7.

尝试运行 python2.7 --version 。如果这样给您提供类似 Python 2.7.x 的输出，那么您就很好。只需编辑 cqlsh 脚本，并将 python 替换为 python2.7 在文件中唯一代码行的开头。

Try running python2.7 --version. If that gives you an output like Python 2.7.x you are good. Just edit the cqlsh script and replace python with python2.7 at the beginning of the only code line in the file.
