Errors when trying to stream from the Twitter API

问题

I am trying to stream data from Twitter, by using StreamR and this guide https://github.com/pablobarbera/streamR

It worked recently, but now I get this error when I try to stream any data;

library(ROAuth)
library(streamR)

my_oauth <- list(consumer_key = "...",
   consumer_secret = "...",
   access_token="...",
   access_token_secret = "...")

getUsers(screen_names="LSEnews", oauth = my_oauth)

#Error in function (type, msg, asError = TRUE)  : 
  #Unknown SSL protocol error in connection to api.twitter.com:443

When I try to stream tweets the connection closes after 0 second

filterStream(file.name="trump-tweets.json", track="trump", timeout=120, oauth=my_oauth)
#Capturing tweets...
#Connection to Twitter stream was closed after 0 seconds with up to 0 tweets #downloaded.

I have re-generated my costumerkeys and access tokens on the Twitter developer site and also created a new app. I have also tried to update the ROAuth and streamR -package. However, when I try to update streamR from github, I get this error (I have installed the package before without any problems);

library(devtools)

#Loading required package: usethis
devtools::install_github("pablobarbera/streamR/streamR")

#Error in rethrow_call(c_processx_exec, command, c(command, args), stdin,  : 
#  Incorrect number of arguments (16), expecting 14 for 'processx_exec'

Which led me to this answer that I might need to update the processx package

https://github.com/r-lib/devtools/issues/2077

Which I have updated by

install.packages("processx")

But it did not solve the problem, I still get the same error when I try to update the StreamR package from Github. I have also tried to install the streamR-package through CRAN;

install.packages("streamR")
install.packages("ROAuth")

But it did not solve my primary problem about streaming tweets.

Any help is appreciated, thanks!

回答1:

I was able to successfully run the code as per below (proving that it is indeed an issue with your setup and nothing has changed in the API or package itself).

A couple notes:

I installed the github version of streamR
Notice that I couldn't run the function getUsers; I suspect that function is from the CRAN version
I've included the output of sessionInfo(); perhaps if you ensure you have the same package versions and R version as I do you will be able to run successfully or at least lead you in the direction
