无法在Fish-shell中使用conda运行源激活

Question

我关注了conda_PR_545，conda issues 4221，但仍然没有在Ubuntu上工作。

从here下载conda.fish后，将其mv到anaconda3/bin/。

在~/.config/fish/config.fish的末尾添加"source /home/phejimlin/anaconda3/bin/conda.fish“。

conda activate spark_env
Traceback (most recent call last):
File "/home/phejimlin/anaconda3/bin/conda", line 6, in 
sys.exit(conda.cli.main())
File "/home/phejimlin/anaconda3/lib/python3.6/site-packages/conda/cli/main.py", line 161, in main
raise CommandNotFoundError(argv1, message)
TypeError: init() takes 2 positional arguments but 3 were given

或

activate spark_env
Error: activate must be sourced. Run 'source activate envname'
instead of 'activate envname'.

我错过了什么吗？

Answer 1

从fish 2.6.0CONDA 4.3.27开始:以下步骤可能会更改为

更新配置

记下你的conda的位置

conda info --root
/Users/mstreeter/anaconda    # this is my <PATH_TO_ROOT>

将行添加到~/.config/fish/config.fish

 source <PATH_TO_ROOT>/etc/fish/conf.d/conda.fish

更新约定

通常，您将从bash运行以下命令

source activate <environment>
source deactivate <environment>

现在，您必须从fish运行以下命令

conda activate <environment>
conda deactivate <environment>

问题

因此，在这样做之后，我无法将fish设置为我的默认shell，并且它仍然可以在conda__中正常工作。目前，我必须首先进入我的默认外壳，然后输入fish，外壳就会按预期工作。在我发现如何让它完全正常工作后，我将更新它，而不需要在每次登录到我的终端时显式地选择fish

如果您遵循https://github.com/conda/conda/issues/2611，则步骤如下(从头开始)：

[root@6903a8d80f9b ~]# fish
root@6903a8d80f9b ~# echo $FISH_VERSION 
2.4.0
root@6903a8d80f9b ~# bash Miniconda2-4.3.11-Linux-x86_64.sh -b -p /conda
root@6903a8d80f9b ~# source /conda/etc/fish/conf.d/conda.fish
root@6903a8d80f9b ~# conda activate root
root@6903a8d80f9b ~# conda create -yn fishtest                              (root)

Solving package specifications: 
Package plan for installation in environment /conda/envs/fishtest:

# To activate this environment, use:

#
# To deactivate this environment, use:

root@6903a8d80f9b ~# conda activate fishtest                                (root)

root@6903a8d80f9b ~# conda deactivate fishtest                          (fishtest) 

Answer 3

从conda 4.4.0 https://github.com/conda/conda/blob/master/CHANGELOG.md#440-2017-12-20开始，不建议将conda的bin目录添加到路径中

您所需要做的就是向config.fish添加source <path-to-anaconda>/etc/fish/conf.d/conda.fish。
