r - 错误: Package or namespace load failed

Question

当我在 R 中加载一些库时，出现以下错误:

library(forecast) Error : object ‘f_eval’ is not exported by 'namespace:lazyeval' In addition: Warning message: package ‘forecast’ was built under R version 3.3.2 Error: package or namespace load failed for ‘forecast’

library(tsoutliers) Error : object ‘f_eval’ is not exported by 'namespace:lazyeval' In addition: Warning message: package ‘tsoutliers’ was built under R version 3.3.2 Error: package or namespace load failed for ‘tsoutliers’

我已尝试重新安装软件包，但没有帮助。另外，我之前可以使用预测包，但在安装 tsoutliers 包后我开始遇到此错误。

如何解决这个问题？

Answer 1

这应该适合你:

install.packages('lazyeval')
