Directions to install feather on a Windows 7 (64 bit) machine

  1. upgrade to 3.3.0 R: as directed from the original announcement post "Feather uses C++11, so if you’re on windows, you’ll need the new gcc 4.93 toolchain. (All going well this will be included in R 3.3.0, which is scheduled for release on April 14. We’ll aim for a CRAN release soon after that)."

  2. install.packages("feather"); library(feather)

  3. write_feather(df, path) in R:
    this took less than 2 minutes to write a ~0.5 Gb file, where as readr::write_csv was stopped yesterday after writing 0.1 Gb in 2 hours (I had to go home)

  4. pip install feather-format in windows command line (cmd) error: Unable to find vcvarsall.bst
