如何获得RCurl以连接到OS X Yosemite上的POST SSL? [英] How do I get RCurl to connect to POST SSL on OS X Yosemite?

问题描述

自从升级到OS X Yosemite 10.10.2以来，我一直无法使用RCurl通过SSL发送POST.我收到的错误消息是:

Since upgrading to OS X Yosemite 10.10.2, I have been unable to use RCurl to send POSTs via SSL. The error message I get is:

Error in function (type, msg, asError = TRUE) :
    SSLRead() return error -9806

这非常类似于此处的卷曲错误: osx 10.10将URL POST发送到HTTPS URL会导致SSLRead()错误

This strongly resembles the curl error here: osx 10.10 Curl POST to HTTPS url gives SSLRead() error

因此，按照该问题的答案，我运行了通过自制程序安装libcurl的说明，但是我不知道如何将RCurl链接到新的libcurl. curl-config仍会返回旧版本的libcurl.

So I ran the instructions to install libcurl via home-brew, per the answers on that question, but I cannot figure out how to link RCurl to the new libcurl. curl-config still returns the old installation of libcurl.

推荐答案

想通了！

首先，我从自制软件安装了brew:

First, I installed brew from homebrew:

brew install --with-libressl curl

然后，我复制了curl-config:

Then, I copied the curl-config in place:

sudo cp /usr/bin/curl-config /usr/bin/curl-config.bak
sudo cp /usr/local/opt/curl/bin/curl-config /usr/bin/curl-config

然后，我重新安装了RCurl:

Then, I reinstalled RCurl:

install.packages("RCurl", type="source")

它再次起作用.
