R devtools :: install_github（）下载错误：未经授权

Question

I'm trying to tie R to Twitter and everything I try has been failing. I've been looking at several links including the following: One , Two , Three

While those have led to more issues, I'm now looking at the links here and here to try some workarounds. I would have posted my question as a comment to either of these links but I don't have enough rep yet.

When I run the following code, I get the following error

Code:

library(base64enc)
library(RCurl)
library(httr)
set_config( config( ssl_verifypeer = 0L ) )
devtools::install_github("jrowen/twitteR", user="MY_USERNAME", password="MY_PASSWORD", ref = "oauth_httr_1_0")

Error:

WARNING: Rtools is required to build R packages, but is not currently installed.
Please download and install Rtools 3.3 from http://cran.r-project.org/bin/windows/Rtools/ and then run find_rtools().
Downloading GitHub repo jrowen/twitteR@oauth_httr_1_0
Error in download(dest, src, auth) : client error: (401) Unauthorized

Am I just completely missing something here in how to download this dev twitteR package? Does anyone have an idea on how to get past the 401 error?

Thanks,

Have you installed and sourced R tools in the session you are referencing above? You aren't getting a certificate error (were you before?) which suggests you don't have a certificate server you're running under as was the issue in some of your linked posts.

I would suggest the following steps to find your issue.

You may need the httpuv package which can be downloaded sourced with

install.packages('httpuv')
library('httpuv')

Sometimes the twitteR package needs an older version of httr to work correctly, depending on jrowen's (and hadley's) updates.

You may try installing the older version of httr

 devtools::install_version("httr", version="0.6.0", repos="http://cran.us.r-project.org")

and restarting R and then trying your install again. Note that if you are on a 64-bit machine, you will probably have to install the most recent version of httr first, then install the older version.
