Issue #21692 has been updated by mame (Yusuke Endoh). I think what you want is `bundle install --prefer-local`. (I wonder why this option is not the default.) ---------------------------------------- Bug #21692: Basic gems like `date` require a compiler https://bugs.ruby-lang.org/issues/21692#change-115232 * Author: getajobmike (Mike Perham) * Status: Open * ruby -v: 3.4.5 * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- I'm trying to use Ruby in a high security environment which does not allow a compiler to be installed. This was easy years ago when all of standard library was included with Ruby itself and I could use `apt install ruby`. But as the standard library has broken off into separate, optional gems it has become impossible to `bundle` a reasonable pure Ruby application without requiring basic gems like `date` which require a compiler to install. Are there any plans to make native extensions optional for gems? With tools like ZJIT it can be better to use pure Ruby for performance; I would like to see Ruby encourage fewer native extensions and/or make them optional. -- https://bugs.ruby-lang.org/
