Rstudio安装org.Hs.eg.db

自己也是个小白，初次安装org.Hs.eg.db碰到好多问题，步骤总结如下：

第一，instal.packages（）安装，不行则换 BiocManager：：install（）

第二，如BiocManager不成，说明不是最新版本，可按提示安装最新版

BiocManager::install(version = '3.13') #由于R版本较新，按照提示中的相关信息，安装最新版本的

第三，再次安装

BiocManager：：install("org.Hs.eg.db")

 第四，之后每个人碰到问题就不一样了，我遇到的问题是

             类似于包不能因移除，而无法更新（有11个警告信息,不详细列举）

Bioconductor version 3.13 (BiocManager 1.30.16), R 4.1.0 (2021-05-18)
Old packages: 'gert', 'RCurl', 'readr', 'survival', 'XML'
Update all/some/none? [a/s/n]: 
a
#更新过后报错（中间代码省略）
package ‘stringi’ successfully unpacked and MD5 sums checked
Warning: cannot remove prior installation of package ‘stringi’ 
Warning: restored ‘stringi’

解决办法：packages——找到与报警信息对应包——点击❌去除相应包（之后可再安装）

 第五，再次BiocManager：：install("org.Hs.eg.db")

第六，最后library("org.Hs.eg.db")，出现以下代码，恭喜你安装成功
