无法更改网状(R)中的python路径 [英] Unable to change python path in reticulate (R)

问题描述

启动rstudio会话时，我运行的第一行是:

The first lines I run when launching my rstudio session are:

library(reticulate)
use_python("/usr/local/lib/python3.6/site-packages")

但是，当我运行py_config()时，它显示仍在使用默认的python 2.7安装.

However, when I run py_config() it shows as still using the default python 2.7 installation.

这是一个问题b.c我无法导入为python3安装的任何模块.知道为什么这行不通吗?我相当仔细地遵循了文档.

This is an issue b.c I'm unable to import any modules that were installed for python3. Any idea why this isn't working? I followed documentation fairly closely.

推荐答案

我发现.RProfile中的"use_python('path')"技术和Sys.setenv(RETICULATE_PYTHON ='path')的策略都不适用于我(当然，我确信它一定对其他人有用.)

I observed that neither the technique "use_python('path')" nor the tactic of Sys.setenv(RETICULATE_PYTHON = 'path') in .RProfile worked for me (of course I am sure it must have worked for others.)

在任何情况下，终端上的行

In any case the line at terminal,

which -a python python3

产生了两个可供选择的路径(一个用于在我的mac上安装的python2，一个用于安装在我的mac上的python3)，因此我能够在主目录中创建一个".Renviron"文件，其中只有以下一行:

did produce two paths to choose from (one for python2 and one for python3 installed on my mac), so then I was able to create a ".Renviron" file in my home directory with this single line in it:

RETICULATE_PYTHON="/usr/local/bin/python3"

重新启动RStudio后，library(reticulate)激活所需的python3，然后repl_python()打开python3交互式窗口，等等.

After I restarted RStudio, library(reticulate) activates the desired python3, and repl_python() opens a python3 interactive window, etc. etc.
