手动安装R包stringi

因为 https://raw.githubusercontent.com/gagolews/stringi/master/src/icu69/data/icu4c-69_1-data-bin-l.zip被墙, 需要手动安装stringi:

In addition: Warning messages:

在github下载源码, 再解压到my_packages,最后手动安装:

/opt/R/R-4.0.2/bin/R CMD INSTALL --configure-vars='ICUDT_DIR=/opt/R/R-4.0.2/my_packages/stringi-master/src/icu69/data' stringi_1.7.12.tar.gz

最后成功的结果是这样的:

installing via 'install.libs.R' to /opt/R/R-4.0.2/lib64/R/library/00LOCK-stringi/00new/stringi
