从bash脚本调用conda源激活 [英] calling conda source activate from bash script

问题描述

我正在尝试通过bash脚本激活我的conda env.即使脚本运行正常，并且我的PATH在脚本中似乎已更改，但在脚本终止后仍会以某种方式重置.我可以从cmd行调用source activate test，它可以正常工作.一个示例以及下面的输出.

I'm trying to activate my conda env via a bash script. Even though the script runs fine and my PATH appears to be changed within the script, it's getting reset somehow after the script terminates. I can call source activate test from the cmd line and it works fine. An example along with output below.

脚本:

PycharmProjects/test » cat ./example.sh
echo "before calling source: $PATH"
source activate test
echo "after calling source: $PATH"

输出:

./example.sh
before calling source: /Use rs/me/miniconda3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin

discarding /Users/me/miniconda3/bin from PATH
prepending /Users/me/miniconda3/envs/test/bin to PATH

after calling source: /Users/me/miniconda3/envs/test/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin`

，但是如果我在脚本完成后echo $PATH，您会看到$PATH尚未更改(即，没有/Users/me/miniconda3/envs/test/bin):

but if I echo $PATH after the script finishes, you can see that the $PATH has not changed (i.e. no /Users/me/miniconda3/envs/test/bin):

PycharmProjects/test » echo $PATH /Users/me/miniconda3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin

推荐答案

在最新版本的conda(4.6+)上，我注意到有以下作品:

On more recent versions of conda (4.6+), I have noticed that the following works:

eval "$(conda shell.bash hook)"
conda activate <env-name>
