merb -i problem with 1.0.9

[IndianGuru]

I am using merb 1.0.9 on Windows.

When I type:
---------------
E:\ruby_simple_app> merb -i
Loading init file from E:/ruby_simple_app/config/init.rb
Loading E:/ruby_simple_app/config/environments/development.rb
~
~ ←[1;31;47mFATAL: The gem dm-types (= 0.9.10, runtime), [] was not
found←[0m
~
E:\ruby_simple_app>
----------------

I get the above error - The gem dm-types (= 0.9.10, runtime), [] was
not found

My dependencies.rb has:
merb_gems_version = "1.0.9"
dm_gems_version = "0.9.10"
do_gems_version = "0.9.11"

amongst other things.

When I type:
----------------

E:\ruby_simple_app> gem install dm-types
Building native extensions. This could take a while...
ERROR: Error installing dm-types:
ERROR: Failed to build gem native extension.

What is the problem? All help appreciated.

In DM 0.9.10 dm-types has a dependency on BCrypt.

What's going on here is that RubyGems is trying to build the BCrypt
native extension on your Windows box, but it looks like you don't have
a suitable compiler Visual Studio / nmake) available.

BCrypt is actually optional (its only needed by one custom type) - and
as of this commit -
http://github.com/datamapper/dm-more/tree/d37f392ce69e5bfbc71b0aa8abade5dd22c00c63
- its not included as a gem dependency.

You may want to try installing edge DataMapper to see if the problem persists.

Alex is absolutely right, note that DM removed the dependency on their "edge" version but a new Merb release doesn't mean that DM released a new version. So, the problem you previously had isn't fixed with this Merb release.

@ Indian Guru.

Perhaps this paragraph by Mr. Matt just posted in another thread in
the same forum may help you.
---------------------------------------------------------------------------------------
DataMapper was not updated in the last few days, so if you had issues
with
DM Type on Windows, you will still have this issue, and the only
solution is
to get DM types from the repo and build the gem yourself.

Hope this helps
