我正在运行miniconda2（python2.7 安装）。我没有尝试并排使用miniconda3 ，而是尝试创建一个 python3.5 环境。但是，当我尝试导入 numpy 时出现错误，因为 python 尝试为 python2.7 加载 numpy。我假设这是因为我设置的环境变量.bashrc指向miniconda2安装。
解决此问题的最佳方法是什么？有没有办法可以并排使用 conda python2 和 python3 ？
我的.bashrc有：
export PYTHONLIB="/home/exacloud/lustre1/CompBio/miniconda2/lib"
export PYTHONPATH="/home/exacloud/lustre1/CompBio/miniconda2/lib/python2.7/site-packages"
export PYTHONUSERBASE="/home/exacloud/lustre1/CompBio/miniconda2"
export CONDA_BIN="/home/exacloud/lustre1/CompBio/miniconda2/bin"
