macOS が 10.13.6 なのがきっといけないのだろうと思うが、そこじゃない場所で解決を試みる。 コメントにて、OS も関係ないとのご指摘。 ld: warning: The i386 architecture is deprecated for macOS (remove from the Xcode build setting: ARCHS)
の辺りを調べればいいかもしれないのですが、それはまたの機会に。
解決後に Gemfile.lock
を見ると、 ffi
の依存指定は一箇所のみで、こうなっていた。
rb-inotify (0.10.0)
ffi (~> 1.0)
ffi (~> 1.0)
とあるので、 ffi
の 1.x
の最新版(当時は 1.11.0
)を取ろうとして、それがインストールできていない。
解決方法
~> 1.0
ということは 1.11.0
が必要なわけじゃないはずので、 Gemfile
を書き換えて、インストールできるバージョンに固定した。( 1.9.21
は、あくまで例です)
gem 'ffi', '= 1.9.21'
(これは要らないかもしれない) 事前にインストールしておく。
$ sudo gem install ffi -v '1.9.21'

で、改めて bundle install
$ bundle install --path vendor/bundle
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

バージョンの選び方
ffi 1.9.21
を選ぶべきだというわけではないのですが、あらかじめ mac 側にインストールしてある可能性(他の ruby プログラムを動かすためにインストールしたことがあった、など)を考えれば、たとえば gem list
で調べればインストール可能なバージョンがわかるはず
$ gem list ffi
*** LOCAL GEMS ***
ffi (1.9.21)
public_suffix (3.0.3)
それ以外では、 https://rubygems.org/gems/ffi/versions を見て、一つ前のバージョンの最新を選ぶと良いと思います。今回だと、失敗したのは 1.11.0
なので、 1.10.x
の中での最新の 1.10.0
を試す、それでもダメなら 1.9.25
を試す、...を繰り返す、など。
時間がある人は、もちろん原因を特定してそれが解決できる最新のバージョンを選びましょう。
