[jira] [Comment Edited] (ARROW-6169) A bit confused by arrow::install_arrow() inR

----------------------------------------------------------------

Have finally managed to get things working by installing from the right tag on GH:
{code:java}
$brew link apache-arrow #undoing earlier unlink
>remotes::install_github("apache/arrow", subdir = "r", ref = "apache-arrow-0.14.1"){code}
Next step is to try and get this to play well with GitLab CI on Ubuntu... any chance there's a Dockerfile laying around already? :)

> Am trying to get up and running on arrow from R for the first time (macOS Mojave 10.14.6)
> Started with
> {code:java}
> install.packages('arrow') #success!
> write_parquet(iris, 'tmp.parquet') #oh no!{code}
> and hit the error:
> > Error in Table__from_dots(dots, schema) : Cannot call Table__from_dots(). Please use arrow::install_arrow() to install required runtime libraries. 
> OK, easy enough:
> {code:java}
> arrow::install_arrow() 
> {code}
> With output:
> {code:java}
> You may be able to get a development version of the Arrow C++ library using Homebrew: `brew install apache-arrow --HEAD` Or, see the Arrow C++ developer guide <https://arrow.apache.org/docs/developers/cpp.html> for instructions on building the library from source.
> After you've installed the C++ library, you'll need to reinstall the R package from source to find it.
> Refer to the R package README <https://github.com/apache/arrow/blob/master/r/README.md> for further details.
> If you have other trouble, or if you think this message could be improved, please report an issue here: <https://issues.apache.org/jira/projects/ARROW/issues>
> {code}
> A few points of confusion for me as a first time user:
> A bit surprised I'm being directed to install the development version? If the current CRAN version of {{arrow}} is only compatible with the dev version, I guess that could be made more clear in this message. But on the other hand, the linked GH README suggests the opposite: "On macOS and Windows, installing a binary package from CRAN will handle Arrow’s C++ dependencies for you." However, that doesn't appear to have been the case for me.
> Oh well, let's just try installing the normal version & see if that works:
> {code:java}
> $brew install apache-arrow
> >install.packages('arrow') #reinstall in fresh session
> >arrow::write_parquet(iris, 'tmp.parquet') # same error{code}
> Now I try the dev version:
> {code:java}
> brew install apache-arrow --HEAD
> # Error: apache-arrow 0.14.1 is already installed
> # To install HEAD, first run `brew unlink apache-arrow`.
> brew unlink apache-arrow
> brew install apache-arrow --HEAD
> # Error: An exception occurred within a child process:
> # RuntimeError: /usr/local/opt/autoconf not present or broken
> # Please reinstall autoconf. Sorry :(
> brew install autoconf
> brew install apache-arrow --HEAD
> # Error: An exception occurred within a child process:
> # RuntimeError: /usr/local/opt/cmake not present or broken
> # Please reinstall cmake. Sorry :(
> brew install cmake
> brew install apache-arrow --HEAD
> # cmake ../cpp -DCMAKE_C_FLAGS_RELEASE=-DNDEBUG -DCMAKE_CXX_FLAGS_RELEASE=-DNDEBUG -DCMAKE_INSTALL_PREFIX=/usr/local/Cellar/apache-arrow/HEAD-908b058 -DCMAKE_BUILD_TYPE=Release -DCMAKE_FIND_FRAMEWORK=LAST -DCMAKE_VERBOSE_MAKEFIL

> Poked around a bit about that error and what I see suggests re-installing {{scipy}} but that didn't work ({{pip install scipy}} nor {{pip3 install scipy}}, though the traceback does suggest it's a Python 3 thing)
> So now I'm stuck & not sure how to proceed.
> I'll also add that I'm not sure what to make of this:
> > After you've installed the C++ library, you'll need to reinstall the R package from source to find it.
> What is "find it" referring to exactly? And installing from source here means {{R CMD build && R CMD INSTALL}} on the cloned repo?
