在Mac上更改默认的python版本-安装Biopython [英] Changing the default python version on Mac - Installing Biopython

问题描述

我的Mac随python 2.7一起安装为默认python版本.但是，许多软件包和软件不再支持此版本.我搜索了几个在线论坛，以了解如何在Mac上更改默认的python版本.但是，它们似乎都不起作用.我还安装了最新版本的python，如果输入:

My Mac came installed with python 2.7 as the default python version. But, this version is no longer supported by many packages and software. I searched several online forums regarding how to change the default python version on mac. But, none of them seem to work. I also installed the latest version of python, and if I type:

python --version

python --version

它将版本返回为python 3.8.但是，如果我尝试安装像Biopython这样的软件包，则会收到这样的错误-

It returns the version as python 3.8. But if I try to install packages like Biopython, I get an error like this -

默认为用户安装，因为常规站点包不是可写的

defaulting to user installation because normal site-packages is not writeable

使用缓存的biopython-1.77.tar.gz(16.8 MB)收集biopython

Collecting biopython Using cached biopython-1.77.tar.gz (16.8 MB)

错误:命令错误，退出状态为1:

ERROR: Command errored out with exit status 1:

Biopython需要Python 3.6或更高版本.检测到Python 2.7

Biopython requires Python 3.6 or later. Python 2.7 detected

我真的发现很难安装工作所需的许多软件包.任何帮助或建议，将不胜感激.

I am really finding it difficult to install many packages required for my work. Any help or suggestions would be greatly appreciated.

谢谢.
