由于依赖关系，安装devtools失败，但对于我拥有的R版本，依赖项不可用

Question

configure: error: 
---------------------------------------------
  OpenSSL library required

  Please install:
  libssl-dev (deb) or openssl-devel (rpm)
---------------------------------------------
See `config.log' for more details
ERROR: configuration failed for package ‘git2r’
 * removing ‘/home/udi/R/x86_64-pc-linux-gnu-library/3.2/git2r’
ERROR: dependency ‘openssl’ is not available for package ‘httr’
 * removing ‘/home/udi/R/x86_64-pc-linux-gnu-library/3.2/httr’
ERROR: dependencies ‘httr’, ‘git2r’ are not available for package ‘devtools’
 * removing ‘/home/udi/R/x86_64-pc-linux-gnu-library/3.2/devtools’

然而，当我试图安装libssl-dev (我有Ubuntu14.04.3)时，我得到了消息“‘libssl-dev’是不可用的(对于RVersion3.2.2)”。

知道该怎么做吗？下载一个新的R版本或有任何其他解决方案？

Answer 1

那是一个系统包-不是R包。从命令行中可以运行

sudo apt-get install libssl-dev

Answer 2

解决我的Ubuntu问题的地方是安装这个：

sudo apt-get install zlib1g-dev

除非你这样做，否则它不会立即显现出来：

install.packages("git2r")

它将抛出此错误：

The zlib library that is required to build
   git2r was not found.

   Please install:
     zlib1g-dev (package on e.g. Debian and Ubuntu)
     zlib-devel (package on e.g. Fedora, CentOS and RHEL)
   and try again.
