R / RStudio-安装devtools失败？ [英] R/ RStudio - install devtools fails?

问题描述

我正在尝试在RStudio中安装 devtools 。但是我遇到了很多错误：

I am trying to install devtools in my RStudio. But I get tons of errors:

* installing *source* package ‘curl’ ...

Perhaps you should add the directory containing `libcurl.pc'
to the PKG_CONFIG_PATH environment variable

   If the OpenSSL library is installed on

   is unable to find it, you can specify
   the include and lib path to OpenSSL with:
   R CMD INSTALL --configure-args='--with-libssl-include=INCLUDE_PATH --with-libssl-lib=LIB_PATH' git2r

所以我尝试安装 libcurl ：

> install.packages("libcurl")
Installing package into ‘/home/lau/R/x86_64-pc-linux-gnu-library/3.4’
(as ‘lib’ is unspecified)
Warning in install.packages :
  package ‘libcurl’ is not available (for R version 3.4.0)
> install.packages("curl")

我在Ubuntu 17.04上。和R 3.4。

I'm on Ubuntu 17.04. And R 3.4.

有什么想法可以解决此问题吗？

Any ideas how I can fix this?

推荐答案

错误消息可能有点令人困惑，因为RStudio要求您为Linux操作系统安装libcurl和openssl库。对于那些实际上需要Ubuntu软件包而不是R软件包的人。

The error messages may be a bit confusing, because RStudio is asking you to install libcurl and openssl libraries for your Linux OS; for those you actually need Ubuntu packages instead of R packages.

打开命令行终端，然后键入

Open a command line terminal, and type

sudo apt-get install libcurl4-openssl-dev libssl-dev 

一旦完成Ubuntu软件包的安装，请重试，您将能够安装devtools R软件包

Once the installation of your Ubuntu packages is completed, try again and you'll be able to install the devtools R package
