無法在R Studio中加載SWIRL軟件包

Question

加載漩渦包裝時出現以下錯誤

library("swirl", lib.loc="~/R/x86_64-pc-linux-gnu-library/3.2")
Error : .onAttach failed in attachNamespace() for 'swirl', details:
call: str_c(..., sep = " ")
error: lazy-load database '/home/ganesh/R/x86_64-pc-linux-gnu-library  /3.2/stringi/R/stringi.rdb' is corrupt
In addition: Warning messages:
1: In str_c(..., sep = " ") : restarting interrupted promise evaluation
2: In str_c(..., sep = " ") : internal error -3 in R_decompress1
Error: package or namespace load failed for ‘swirl’

如您所見，R版本是3.2，它在Ubuntu 15.04 64位上運行。

請求您的幫助。

謝謝

Ubuntu 15.04也在這里，一切都很好：

edd@max:~$ r -e 'library(swirl); cat("All OK\n")'

| Hi! I see that you have some variables saved in your workspace. To keep

| Type ls() to see a list of the variables in your workspace. Then, type
| rm(list=ls()) to clear your workspace.

| Type swirl() when you are ready to begin.

All OK
edd@max:~$

如您所見，該軟件包在這里干凈安裝，不需要任何依賴（也許是因為我已經安裝了很多軟件包）並且可以正常加載。

我經常從命令行安裝和測試，並在littler中使用install.r包裝器- sudo apt-get install littler 。
