在rmarkdown中使用python时出错py_call_implcallable，dots $ args，dots $ keywords中的错误...

如何解决在rmarkdown中使用python时出错py_call_implcallable，dots $ args，dots $ keywords中的错误...

我有以下rmarkdown代码：

---
title: "test"
output: html_document
---

```{r setup,include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(reticulate)
use_condaenv(condaenv = "daniellgaenv",conda = r"(C:\Users\danie\anaconda3\envs\daniellgaenv)",required = TRUE)
```

```{python}
a = [1,2,3]
```

在运行python块时，它给了我错误：

Error in py_call_impl(callable,dots$args,dots$keywords) : 
  TypeError: use() got an unexpected keyword argument 'warn'

我的系统信息：

和来自网状结构：

NOTE: Python version was forced by use_python function

使用repl_python在终端上工作时，相同的代码也起作用：

> reticulate::repl_python()
Python 3.7.9 (C:/Users/danie/anaconda3/envs/daniellgaenv/python.exe)
Reticulate 1.16 REPL -- A Python interpreter in R.
>>> a = [1,3]
>>> a
[1,3]

有人知道如何解决此问题吗？

解决方法

该问题应通过网状结构的开发版本解决
