Hi folks,

did someone of you experience this as well?

$ uname -a
CYGWIN_NT-6.1 arnie 1.7.32(0.274/5/3) 2014-08-13 23:06 x86_64 Cygwin
$ ruby --version
ruby 2.0.0p481 (2014-05-08) [x86_64-cygwin]
$ gem --version
2.4.1
$ gem list -l

Apparently when reading a file the environment’s encoding information
is applied. I’m just not sure whether this is an issue with gem
command or a Cygwin adjustment to that.

Bonus points for a solution. :slight_smile:

Kind regards

Hrm… do you have a ~/.gemrc?

Otherwise, try something like:

ruby -E US-ASCII -S gem update --system

No. I had a directory ~/.gem. But moving that away does not make a
difference.

Otherwise, try something like:

ruby -E US-ASCII -S gem update --system

I don’t expect that this will make a difference - and, yes:

$ ruby -E US-ASCII -S gem update
Updating installed gems
ERROR: While executing gem … (ArgumentError)

Setting LANG in the environment is even more effective as you can see
on the error message:

$ LANG=C ruby -S gem update
Updating installed gems
ERROR: While executing gem … (ArgumentError)
invalid byte sequence in US-ASCII

If only the file read was mentioned… Oh wait, I have a solution:

$ LANG=C.BINARY ruby -S gem update

“LANG=C.BINARY gem update” works, too.

Thank you, Ryan!
