conda search -f python 中沒有可用的 Python 3.6

Question

如果我運行：

conda search -f python 

沒有 Python <3.8 可用...我怎樣才能得到它？

我得到的輸出如下：

Answer 1

這就是我所看到的。 您可能想要添加一些頻道並使用conda search python ：

$ conda search python
Loading channels: done
# Name                       Version           Build  Channel             
python                         1.0.1               0  conda-forge         
python                           1.2               0  conda-forge         
...
python                      3.6.0rc1               0  conda-forge         
python                         3.6.0               0  conda-forge         
python                         3.6.0               1  conda-forge   
...      
python                        3.6.13 haf480d7_1_cpython  conda-forge         
python                        3.6.13 haf480d7_2_cpython  conda-forge         
python                        3.6.15 haf480d7_0_cpython  conda-forge         
python                         3.7.0   h145921a_1002  conda-forge         
python                         3.7.0   h145921a_1003  conda-forge         
python                         3.7.0   h145921a_1004  conda-forge  
...
   
python                        3.10.5 hdaaf3db_0_cpython  conda-forge         
python                        3.10.5 hdd68b96_0_cpython  conda-forge       

$ cat ~/.condarc
channels:
  - conda-forge
  - bioconda
  - defaults

筆記：

您還可以搜索確切的版本，例如：

$ conda search 'python=3.6'
Loading channels: done
# Name                       Version           Build  Channel             
python                       3.6.0a3               0  conda-forge         
python                       3.6.0a4               0  conda-forge         
...
python                        3.6.13 haf480d7_2_cpython  conda-forge         
python                        3.6.15 haf480d7_0_cpython  conda-forge    

Answer 2

正如這個答案中所解釋的，Conda 僅在osx-arm64平台上支持 Python 3.8+。 但是，您仍然可以創建osx-64環境，並且這些環境將（無縫）在仿真中運行。

要搜索替代平台，可以使用--subdir, --platform參數指定：

conda search --subdir osx-64 python=3.6

或者通過CONDA_SUBDIR環境變量臨時設置subdir配置：

CONDA_SUBDIR=osx-64 conda search python=3.6

請參閱其他問題，了解如何使用這些版本創建環境。
