VSCode中运行R代码出现异常打印问题求助

加载tidyverse库时，输出中出现了显式的ANSI转义字符（如←[1m、←[32m），而非预期的格式化样式，示例输出如下：

> library("tidyverse")
-- ←[1mAttaching packages←[22m -------------------------------------------------- tidyverse 1.3.2 --

当前VSCode用户设置JSON：

解决思路 #

• 禁用R的ANSI颜色输出：在R控制台运行options(cli.num_colors = 1)，临时关闭cli包的颜色格式化；若要永久生效，在用户目录下的.Rprofile文件中添加该行代码。
• 修改VSCode的R启动参数：更新用户设置中的r.rterm.windows为"C:\\Program Files\\R\\R-4.2.2\\bin\\R.exe --no-color"，启动R时直接禁用颜色输出。
• 更换终端环境：Windows Server 2012 R2的默认控制台对ANSI转义字符支持有限，可将VSCode的默认终端切换为Windows Terminal，提升兼容性。
• 更新相关依赖包：运行update.packages(c("cli", "crayon"))，更新负责输出格式化的cli和crayon包，新版本可能修复旧系统的兼容问题。
• 调整LSP设置：尝试关闭r.lsp.debug选项，减少调试输出带来的转义字符解析问题；或检查LSP的输出配置，确保转义字符被正确处理。
