r网状指定python可执行
首先，我在Windows机器上工作。我想指定在Rstudio中使用的特定版本的Python。我希望Rstudio在ArcGIS Pro文件夹中使用Python 3，以便拥有arcpy以及许可的扩展名。我已经安装了网状，并尝试了以下方法迫使rstudio使用python的ArcGis Pro版本。
首先，我尝试了以下操作：
library(reticulate)
use_python("C:/Program Files/ArcGIS/Pro/bin/Python/envs/arcgispro-py3/python.exe", required = TRUE)
结果错误：
Error in path.expand(path) : invalid 'path' argument
遵循其他提示，我在加载网状库之前尝试设置环境。
Sys.setenv(RETICULATE_PYTHON = "c:/Program Files/ArcGIS/Pro/bin/Python/envs/arcgispro-py3/python.exe")
library(reticulate)
然后，我检索有关网状使用当前正在使用的Python版本的信息。
py_config
Error in path.expand(path) : invalid 'path' argument
创建和编辑
usethis::edit_r_environ()
软件包来
RETICULATE_PYTHON="C:/Program Files/ArcGIS/Pro/bin/Python/envs/arcgispro-py3/python.exe"
。
library (reticulate)
py_config()
Error in path.expand(path) : invalid 'path' argument
我还尝试通过使用usethis ..
关于我为什么继续接收无效的'PATH'参数
UPDATE（1/11/24）的任何想法：这似乎不是
First, I'm working on a Windows machine. I would like to specify a specific version of python to use in RStudio. I would like RStudio to use python 3 in the ArcGIS Pro folder in order to have arcpy available, along with the licensed extensions. I have reticulate installed and have tried the following methods to force RStudio to use the ArcGIS Pro version of python.
First I tried this:
library(reticulate)
use_python("C:/Program Files/ArcGIS/Pro/bin/Python/envs/arcgispro-py3/python.exe", required = TRUE)
The resulting error:
Error in path.expand(path) : invalid 'path' argument
Following some other tips, I tried setting the environment before loading the reticulate library.
Sys.setenv(RETICULATE_PYTHON = "c:/Program Files/ArcGIS/Pro/bin/Python/envs/arcgispro-py3/python.exe")
library(reticulate)
Then I retrieve information about the the version of Python currently being used by reticulate.
py_config
Error in path.expand(path) : invalid 'path' argument
I also tried creating and editing the .Renviron by using the usethis package
usethis::edit_r_environ()
Then entering the following
RETICULATE_PYTHON="C:/Program Files/ArcGIS/Pro/bin/Python/envs/arcgispro-py3/python.exe"
And saving it, restarting R..
library (reticulate)
py_config()
Error in path.expand(path) : invalid 'path' argument
And, to confirm, here is the location...
Any ideas on why I continue to receive invalid 'path' argument
UPDATE (1/11/24): This doesn't seem to be an issue with the reticulate package anymore. My current configuration is R version: 4.3.2, reticulate version: 1.34.0, RStudio version: 2023.12.0, ArcGIS Pro version: 3.2.0.

我也有类似的问题。在尝试了各种各样的事情之后，我终于安装了 reticulate 的存档版本（reticulate_1.22），而不是使用最新版本（reticulate_1.23），现在问题消失了。看来这个错误已经引起了开发人员的注意（https://github.com/ rstudio/reticulate/issues/1189）。
I was having a similar issue. After trying a whole assortment of things, I finally installed an archived version of reticulate (reticulate_1.22) instead of using the most up-to-date version (reticulate_1.23) and now the issue is gone. It appears that this bug has been brought to the developers' attention (https://github.com/rstudio/reticulate/issues/1189).
您是否尝试过用
PROGRA~1替换Program Files，并且您是否还检查过诸如dir("path/to/your/env") 这样的命令虽然你的截图看起来不错；顺便说一句，以防万一 - 编辑 .Renviron 文件后，您需要重新启动 RStudio/R 会话才能使更改生效；
RStudio 版本 2022.02 现在在

Program FileswithPROGRA~1and have you maybe also checked for example a command likedir("path/to/your/env")although tbh your screenshot looks ok;btw just in case - after editing your .Renviron file you need to restart your RStudio/R session for changes to take effect;

我在R-4.1.1版本中遇到了相同的错误，但是当我切换回前版本R-4.0.5时，一切都按预期工作。这是一个快速的解决方法，但不能解决当前版本中的基本问题。
I ran into the same error with R version R-4.1.1, but when I switched back to the previous version R-4.0.5 everything worked as expected. It's a quick workaround but doesn't solve the underlying issue in the current version.
