“在Python3上不应访问此包”错误

Question

我根据安装指南（https://www.phenix-online.org/documentation/install-setup-run.html）在CentOS 7系统上安装了phenix（phenix-installer-1.17.1-3660-intel-linux-2.6-x86_64-centos6）。我的系统中的原始python版本（/usr/bin/python）是2.7.5，但我安装了anaconda3，因此“whichpython”命令的输出是“~/software/build/anaconda3/bin/python”

我试图学习p9 sad教程并运行命令“phenix.run_示例p9 sad”，但它给出了以下错误信息：

Examples to be run:  p9-sad

这是否意味着phenix需要python2而不是python3，但我的系统中有python3，所以出现了错误？如何解决这个问题？先谢谢你

Answer 1

仅基于/home/sunyp/software/Phenix/phenix-1.17.1-install/phenix-1.17.1-3660/conda_base/lib/python2.7/site-packages/reprlib/__init__.py的Phenix包含Python 2.7环境

您可以尝试使用/home/sunyp/software/Phenix/phenix-1.17.1-install/phenix-1.17.1-3660/conda_base/bin/python或其他东西来运行代码以使用Python解释器，但很难说清楚，因为Phenix源代码是不公开的

Answer 2

您的环境可能包含python2.7.5的路径 检查你的PYTHONPATH

这不适用于Python3，原因很明显。要删除它，请执行以下操作：

unset PYTHONPATH
