Anaconda环境安装c7n后无法识别custodian命令的问题

问题初始描述 #

使用Anaconda作为Python包管理器时，在conda环境中找不到可安装的c7n模块。通过Anaconda Prompt用pip安装c7n后，执行conda list却无法看到该模块已安装。

编辑1：详细操作与报错信息 #

在Anaconda Prompt中执行以下命令：

conda activate myenv
pip install c7n

执行pip install后可以看到c7n正在下载，但执行custodian schema时出现错误：

'custodian' is not recognized as an internal or external command,
operable program or batch file.

执行where python得到路径结果：

c:\Users\rthiyagaraja\AppData\Roaming\Python\Python38\site-packages\python.exe
C:\Program Files\Python38\python.exe

再次尝试pip安装c7n时，得到依赖已满足的提示：

Requirement already satisfied: C7n in c:\users\rthiyagaraja\appdata\roaming\python\python38\site-packages (0.9.33)
Requirement already satisfied: boto3==1.33.1 in c:\users\rthiyagaraja\appdata\roaming\python\python38\site-packages (from C7n) (1.33.1)
Requirement already satisfied: urllib3==1.26.18 in c:\users\rthiyagaraja\appdata\roaming\python\python38\site-packages (from C7n) (1.26.18)
Requirement already satisfied: jsonschema==4.20.0 in c:\users\rthiyagaraja\appdata\roaming\python\python38\site-packages (from C7n) (4.20.0)
Requirement already satisfied: argcomplete==3.1.6 in c:\users\rthiyagaraja\appdata\roaming\python\python38\site-packages (from C7n) (3.1.6)

随后尝试基于上述路径创建新conda环境：

conda create --prefix c:\users\rthiyagaraja\appdata\roaming\python\python38\site-packages --copy python=3.8

激活该环境：

conda activate c:\users\rthiyagaraja\appdata\roaming\python\python38\site-packages

但查看已安装包时仍未显示c7n模块，再次执行pip安装仍提示依赖已满足。

编辑2：解决方案（供同类问题用户参考） #

在默认环境或conda环境中安装custodian均未成功，最终通过Python虚拟环境完成安装，步骤如下：

python -m venv custodian 

.\custodian\scripts\activate 

pip install c7n

.\custodian\scripts\activate
