pod installができなかったのを清く泥臭く解決した

TL;DR

• CocoaPodsを使って依存ライブラリをインストールしようとしてできなかったお話。
• gem update xcodeprojするか1.6.0.rc.xを入れれば解決。
• 知ってる人からしたら全然わかってないなお前ってなると思います。

環境

エラー内容のStackを見ておくれ。

CocoaPodsインストール

既に1.5.0が入ってることを知らないでsudo gem install cocoapodsでインストール。

CocoaPods 1.6.0.rc.1 is available.
To update use: `sudo gem install cocoapods --pre`
[!] This is a test version we'd love you to try.

For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.6.0.rc.1

おう、俺もlove youだけどrc版はまた今度な。
この後これがトリガーになってハマることになろうとはこの時s-yoshidaは思いもしｎ（

pod setup

何事も無く終了。
ぼく「かんたーん＾＾」

pod install

いっぱいエラー吐いた。ｵﾝｷﾞｬｰ。

エラーと向き合う

なっがｗなっげぇｗｗｗｗ草生えない（真顔
俺は依存してるライブラリを入れたいだけなんじゃぁぁぁあああ(´・ω・｀)

RuntimeError - [!] Xcodeproj doesn't know about the following attributes {"inputFileListPaths"=>[], "outputFileListPaths"=>[]} for the 'PBXShellScriptBuildPhase' isa.
If this attribute was generated by Xcode please file an issue: https://github.com/CocoaPods/Xcodeproj/issues/new`

ここが怪しい（直感

ってことでググる。「pod install RuntimeError Xcodeproj doesn't know about the following attributes」でググる。

公式のIssueを確認する

先頭に出てきた公式Issueを要チェックや！（雑なリスペクト

Xcodeproj doesn't know about the following attributes {"inputFileListPaths"=>[], "outputFileListPaths"=>[]} for the 'PBXShellScriptBuildPhase' isa #7835

gem update xcodeprojすると解決すると思うぜ！って
@peruginniさんが言ってる。が、直る理由がわからないので一旦ステイ。

原因を探す

Issueをちゃんと追うと、dnkoutsoさんが「its simple, any Xcode 10 project that has a new script phase that has input file list or output file list shows this warning.」って仰ってる。要するにXcode10でプロジェクトを作るとinputFileListPathsとoutputFileListPathsが空だとそのまま空の配列が出力されてしまって、それが原因だよ（意訳）。とのこと。

原因はわかった。で、どうしたら良いんだ...諸事情によりgem update xcodeprojの手段は使わないようにしたい。

解決策を探す

ここでCocoaPods 1.6.0.rc.1 is available.を思い出す。

バージョンを指定しつつ更にググる。

CocoaPods with Xcode 10 RuntimeError Xcodeproj doesn't know about the following attributes

世の中同じことで悩む人はいるんだなぁ...という事で

This is a known bug introduced by Xcode 10 which fixed in CocoaPods 1.6.0. Right now (Jan 2019) it's in beta, so you can install it with

> sudo gem install cocoapods --pre

＼ いそのー！1.6使えば解決できるってさー！ ／

再トライ

インストール済みのCocoaPodsを全てアンイストールして（ここで1.5.0が別で入ってることに気が付く）、sudo gem install cocoapods --preで1.6.0.rc.2をインストール。pod setup pod install共に問題無く終了。先人達は凄い。

さいごのまとめ

やっぱ公式だよ。
