Code should be placed in three backticks as shown below

library(TCGAbiolinks)
错误: package or namespace load failed for ‘TCGAbiolinks’ in runHook(".onLoad", env, package.lib, package):
 lazy-load database 'E:/R-4.0.3/library/biomaRt/R/biomaRt.rdb' is corrupt
此外: Warning message:
In runHook(".onLoad", env, package.lib, package) :
  internal error -3 in R_decompress1

It is implied that your biomaRt installation has a corrupt file. Can you first re-install biomaRt via:

BiocManager::install('biomaRt')

After this, try to load TCGAbiolinks.
