我使用conda创建了一个虚拟环境。
> library(reticulate)
> use_condaenv("env_ret")
> py_discover_config()
python: C:\Program Files\Anaconda3\envs\env_ret\python.exe
libpython: C:/Program Files/Anaconda3/envs/env_ret/python38.dll
pythonhome: C:\PROGRA~1\ANACON~1\envs\env_ret

numpy: C:\PROGRA~1\ANACON~1\envs\env_ret\lib\site-packages\numpy
numpy_version: 1.17.3
python versions found:

C:\Program Files\Anaconda3\envs\my-env\python.exe
但是，我不能使用它：
> py_config()
Error in py_initialize(config$python, config$libpython, config$pythonhome, :
Py_CompileString - The specified procedure could not be found.
> py_available()
[1] FALSE
