Termux-packages: Error installing ffi

[user3710]

Good morning, I would first like to congratulate the excellent app that you guys help maintain.
I am having a problem on rails that does not let me complete the implementation of the bundle.
Sorry I do not know how to format text of code.
the following error occurs:

//
$ gem install ffi -v '1.9.14'
Building native extensions. This could take a while...
ERROR: Error installing ffi:

The gem install ffi fails due to the gem trying to build a bundled copy of libffi, which does not work due to assumptions that /usr/bin/env exists and too old libffi copy.

However, you can build the ffi gem against the system libffi - install the packages:

apt install clang make ruby-dev libffi-dev

After that the ffi gem should build:

gem install ffi

worked perfectly, I could make the installation the gem, but now has the problem in two other gems:
Installing sqlite3 1.3.11 with native extensions
and
Installing rb-inotify 0.9.7
Gem :: Ext :: BuildError: ERROR: Failed to build gem native extension.
follows the whole code, I am now starting on schedule, so we still do not understand these minutiae and problems related problems.
sorry if I'm being boring

sqlite3.h is missing. Try 'port install sqlite3 +universal',
'yum install sqlite-devel' or 'apt-get install libsqlite3-dev'
and check your shared library search path (the
location where your sqlite3 shared library is located).

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

An error occurred while installing sqlite3 (1.3.11), and Bundler
cannot continue.
Make sure that gem install sqlite3 -v '1.3.11' succeeds before
bundling.//

[user3710]

Just an afterthought, the sqlite3 gem appears on the project Gemfile, but does not appear when I run the gem command list, and the bundle can not install it

[fornwall]

Run apt install libsqlite-dev before installing the sqlite3 gem!
