Я следовал инструкциям по установке v8 и libv8 gem. После этого я не могу успешно установить therubyracer 0.12.3. Mkmf.log дросселирует при попытке проверить заголовок v8.h и выдает unknown type name -ошибку.
Моя среда:
- Ruby: 2.6.3
- OSX: 10,15
- xcode-select: 2373
- libv8: 3.16.14.19
- v8:v8@3.15 (через Homebrew) Информация о пиве v8@3.15 = v8@3.15: стабильный 3.15.11.18 (в бутылках) [только для бочонков]
- g ++: Apple Clang версии 11.0.0 (clang-1100.0.33.17)
Я прошел через предложения здесь . Кто-нибудь получил предложения?

`configure': By using --with-system-v8, you have chosen to use the version
(Libv8::Location::System::NotFoundError)
of V8 found on your system and *not* the one that is bundled with
the libv8 rubygem.
However, your system version of v8 could not be located.
Please make sure your system version of v8 that is compatible
with 3.16.14.19 installed. You may need to use the
--with-v8-dir option if it is installed in a non-standard location
