During startup - Warning messages:
1: Setting LC_COLLATE failed, using "C"
2: Setting LC_TIME failed, using "C"
3: Setting LC_MESSAGES failed, using "C"
4: Setting LC_MONETARY failed, using "C"

原因分析

导致这种情况出现的原因是本地环境LANG配置错误, iterm2(终端)运行locale

LANG=
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

解决办法

1. 关闭R, 打开iterm2(终端), 运行一下命令:

defaults write org.R-project.R force.LANG en_US.UTF-8

2. 打开R, 运行以下命令:

system("defaults write org.R-project.R force.LANG en_US.UTF-8")

3. 配置环境, 笔主使用iterm2, 配置.zshrc

vim ~/.zshrc
# 加入如下配置
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

然后重启终端, 或者

source ~/.zshrc

笔主试过1,2 方法, 没有生效, 第3中方法生效.
现在重新打开R, 你会发现告警信息已经不在了.
