问题描述
我想使用 conda 创建不同的环境，每个环境都有不同的 $PYTHONPATH.目前，我每次都必须在我的 .bashrc 中更改环境变量.有没有一种通过 conda 创建多个 python 环境的简单方法，这样我就可以无缝切换(通过源激活)并让相应的 $PYTHONPATHs 自动更新?
I would like to use conda to create different environments, each with a different $PYTHONPATH. Currently, I have to change the environment variables each time in my .bashrc. Is there a simple way of creating multiple python environments via conda, such that I can seamless switch (via source activate) and have the corresponding $PYTHONPATHs update automatically?
推荐答案
您可以在执行任何脚本之前指定 PYTHONPATH，这比更改 .bashrc 更容易
You can specify the PYTHONPATH before you execute any script, which would be easier than changing your .bashrc
例如，要在执行任何脚本之前将当前工作目录放在路径上，您可以这样做
For example, to put the current working directory on the path before executing any script, you can do this
PYTHONPATH=`pwd`: python
如果您不想覆盖整个路径，而只是追加到它
If you didn't want to overwrite the entire path, but just append to it
PYTHONPATH=`pwd`:$PYTHONPATH python
