Ruby在Windows中离线安装gem

Question

I need to install some Ruby gems in Windows in the offline-mode (without internet). I have gem files downloaded from the other PC.

As long as the gem does not require specific options (with -- ), I just execute gem install somegem --local and everything is fine.

But if the gem does require those options, there is a trouble. For example, I want to install sqlite3-1.3.10.gem :

gem install sqlite3 --local -- --with-sqlite3-dir="c:\programs\sqlite"

This returns me an error:

ERROR:  While executing gem ... (OptionParser::InvalidOption)
invalid option: --with-sqlite3-dir=c:\programs\sqlite

What is wrong?

• ruby 2.2.2p95 (2015-04-13 revision 50295) [x64-mingw32]
• Rails 4.2.2

Got the reason. I ran all commands in Windows PowerShell .

Now I tried to do it in usual cmd.exe - and it just worked.

Just for a case here is how I installed sqlite3.gem : followed instructions from https://stackoverflow.com/a/16023062 and executed command:

gem install sqlite3-1.3.10.gem --local --platform=ruby -- '--with-sqlite3-dir="c:/programs/sqlite" --with-sqlite3-lib="c:/programs/sqlite/.libs" --with-sqlite3-include="c:/programs/sqlite"'

Thank you for comments, they helped to correct the command.
