在 RStudio 中安装包时出错：从连接读取错误

Question

I have recently updated both R (version 3.4.1) and RStudio (version 1.0.143) and I am now unable to install packages from Rstudio.

If I install a package in R directly using install.packages() it works fine.

If I try and install a package in Rstudio using either install.packages() or using the package install menu I get the error below. I have tried a few different packages, and have uninstalled and reinstalled both R and RStudio.

To get the error:

Run:

install.packages("lme4")

Output:

Installing package into ‘E:/Documents/R/win-library/3.4’
(as ‘lib’ is unspecified)
also installing the dependencies ‘minqa’, ‘nloptr’, ‘RcppEigen’

Warning in install.packages :
lzma decoding result 10
Error in install.packages : error reading from connection

I am working off my personal computer, below is some of my system info:

Answer 1

This certainly is an issue with your connection:the proxies you are using and repositories configured in your RStudio. I was getting the same error when I was connected to US VPN from India.I disconnected VPN and restarted RStudio and it worked like a charm!

Answer 2

I had the same issue when I tried to install caret .

The best solution is to restart R studio.

Now the install.packages() works fine.

Answer 3

只需重新启动它对我有用的 R 工作室。

Answer 4

I had the same issue after I misspelled a package name when trying to install it. I restarted R Studio and then it worked.

Answer 5

请通过以下选项在 R Studio 中选择合适的 CRAN 镜像：Tools>>>Packages>>>CRAN Mirror（根据您的位置选择合适的 CRAN）。

Answer 6

A simple solution would be to download manually the zip folder of the package and install it with the command : install.packages('package.zip', lib='destination_directory',repos = NULL)

• Package zip : the path to the zip file of the package
• Destination_directory: where the packages are installed by default like C:/Users/unknown/Documents/R/win-library/3.3

Hope it helps
