允许在conda env中使用系统python吗？ [英] Allow use of system python in conda env?

问题描述

是否有一种方法可以强制conda在给定的环境中使用python的系统版本（以及所有系统库）？

Is there a way to force conda to use the system version of python (along with all of the system libraries) in a given env?

我启用了conda在我的shell中，默认情况下会有点烦人，因为如果我尝试运行系统python应用程序，它将获得与期望的版本不同的python版本（* buntu上的python默认为2.7），并且通常会赢得没跑我希望conda的根环境只是重定向到系统python安装。

I have conda enabled by default in my shell, which can get a bit annoying, because if I try to run a system python app, it gets a different version of python to what it is expecting (python still defaults to 2.7 on *buntu), and often won't run. I would like the root env of conda to just be a redirect to the system python install.

推荐答案

只需删除<$ c来自〜/ miniconda3 / bin / 的$ c> python 符号链接似乎可以完成任务。

Simply removing the python symlink from ~/miniconda3/bin/ appears to do the job.

$ which python           
/home/naught101/miniconda3/bin/python
$ rm /home/naught101/miniconda3/bin/python
$ which python                            
/usr/bin/python
$ source activate science                 
discarding /home/naught101/miniconda3/bin from PATH
prepending /home/naught101/miniconda3/envs/science/bin to PATH
(science)$ which python           
/home/naught101/miniconda3/envs/science/bin/python
(science)$ source deactivate                       
discarding /home/naught101/miniconda3/envs/science/bin from PATH
$ which python     
/usr/bin/python

到目前为止，这似乎并未给我造成任何问题。不幸的是，对于〜/ miniconda / bin / python3 来说，这是行不通的，因为在切换到其他使用相同python版本的环境时，conda要求使用它。但是，这个问题最初并没有引起那么多问题。

So far, this doesn't seem to have caused me any problems. Unfortunately the same doesn't work for ~/miniconda/bin/python3, because conda requires it when switching to other envs that use the same python version. However, that one hasn't caused as many problems in the first place.

如果此确实引起了问题，那么撤消就很容易了，只是 cd〜/ miniconda / bin /; ln -s python3 python （或您在conda根环境中使用的python版本）。您可能需要激活/取消激活环境，才能在PATH上重新获得该版本的python。

If this does cause problems, it's easy enough to undo, just cd ~/miniconda/bin/; ln -s python3 python (or what ever version of python you're using in your conda root env). You may need to activate/deactivate an env to get that version of python back on your PATH.
