r - R devtools包安装找不到openssl

问题描述

我正在尝试使用install.package("devtools"). 无法找到 openssl 时安装失败，但openssl version -a表明已安装 LibreSSL 2.8.3。操作系统是 macOS 10.15.1。

这是控制台日志：

* installing *source* package ‘openssl’ ...
** package ‘openssl’ successfully unpacked and MD5 sums checked
** using staged installation
Homebrew 2.2.0
Homebrew/homebrew-core (git revision 434f; last commit 2019-12-03)
Homebrew/homebrew-cask (git revision deedf; last commit 2019-12-03)
Using PKG_CFLAGS=-I/usr/local/opt/openssl@1.1/include -I/usr/local/opt/openssl/include
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because openssl was not found. Try installing:
 * deb: libssl-dev (Debian, Ubuntu, etc)
 * rpm: openssl-devel (Fedora, CentOS, RHEL)
 * csw: libssl_dev (Solaris)
 * brew: openssl@1.1 (Mac OSX)
If openssl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a openssl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
--------------------------------------------------------------------
ERROR: configuration failed for package ‘openssl’
* removing ‘/usr/local/lib/R/3.6/site-library/openssl’
Warning in install.packages :
  installation of package ‘openssl’ had non-zero exit status

我该如何准确地执行错误消息提示的 PATH 内容？或者你有什么其他的补救方法可以建议吗？r 和 macOS 安装都是全新的，所以不应该有任何不寻常的事情搞砸了。

解决方案

由于 LibreSSL 是 OpenSSL 的一个分支，我认为它们足够不同，以至于 devtools 包无法将它们识别为 Openssl。您应该按照控制台日志的建议尝试安装 openssl@1.1。

brew install openssl
