connection_connect(dbname, loadable.extensions, flags, vfs, extended_types) 中的错误:包Rcpp"未提供函数Rcpp_precious_remove"

解决方案

我在使用另一个包时遇到了同样的问题，问题是我运行的是针对先前版本的 Rcpp<编译的最新版本的包/代码>.正如

I have been trying to create a database and installed the "DBI" package, but I am still facing this error. I reinstalled DBI and RSQLite package, but they don’t seem to work.

library("DBI")
con <- dbConnect
(RSQLite::SQLite(), dbname = ":memory:")
dbListTables(con)

Error:

Error in connection_connect(dbname, loadable.extensions, flags, vfs, extended_types) : function 'Rcpp_precious_remove' not provided by package 'Rcpp'

解决方案

I had the same problem with another package and the issue was that I was running a recent version of the package compiled against a previous version of Rcpp. As user20650 points out in the comment, updating Rcpp to 1.0.7 should fix it:

install.packages('Rcpp') 

In RStudio you can also use the packages panel to update the packages, as in the following image:
