python - Conda activate env 适用于 bash 但不适用于结构

Question

我在 ubuntu 16.04 VPS 上使用 fabric 和 python 3.6。如果我 ssh 并使用 bash，我可以这样做:

deploy@server:~$ conda info --envs
# conda environments:
#
python-devel             /home/deploy/miniconda3/envs/python-devel
test                     /home/deploy/miniconda3/envs/test
root                  *  /home/deploy/miniconda3

deploy@server:~$ source activate test
(test) deploy@server:~$

我有以下 Fabric 功能:

def _update_conda_env(site_folder, host):
......

    run(f'source ~/miniconda3/bin/activate test')
    run(f'~/miniconda3/bin/conda info --envs')

这给出了输出:

[deploy@mysite.org] run: source ~/miniconda3/bin/activate test
[deploy@mysite.org] run: ~/miniconda3/bin/conda info --envs
[deploy@mysite.org] out: # conda environments:
[deploy@mysite.org] out: #
[deploy@mysite.org] out: python-devel             /home/deploy/miniconda3/envs/python-devel
[deploy@mysite.org] out: test                     /home/deploy/miniconda3/envs/test
[deploy@mysite.org] out: root                  *  /home/deploy/miniconda3
[deploy@mysite.org] out: 
[deploy@mysite.org] out: 


Done.
Disconnecting from deploy@mysite.org... done.

我怎样才能让它在织物上工作

您的 activate除非您使用 prefix，否则只会保持事件一个周期.

with prefix('source ~/miniconda3/bin/activate test'):
    run(f'~/miniconda3/bin/conda info --envs')

这样，运行 block 中的所有内容都将以 source ~/miniconda3/bin/activate test && 为前缀
