推荐答案

我恢复到yaml R软件包版本2.1.14，并为我修复了该问题。
https://cran.r-project.org/src / contrib / Archive / yaml /

I reverted to yaml R package version 2.1.14 and it fixed it for me. https://cran.r-project.org/src/contrib/Archive/yaml/

使用此R命令从源代码安装软件包（前提是工作目录设置为R软件包所在的位置） ：
install.packages（ yaml_2.1.14.tar.gz，存储库= NULL）

Use this R command to install the package from source (provided the working directory is set to where the R package is): install.packages("yaml_2.1.14.tar.gz", repos = NULL)
