Rails API × GraphQL プロジェクトを作成する際にハマったこと

Posted at

概要

以下の記事を参考にプロジェクトを作ろうとしたところ私のmac環境で次のような問題でハマったためまとめます。

環境

  • macOS Mojave v10.14.6
  • Rails 5.0.7.2

make: *** [mysql2.bundle] Error 1

これはGraphQL関係なく、mysql2の $ bundle install エラーでした。

$ bundle install

解決方法

以下のコマンドを実行した後に再度 $ bundle install すると正常にインストールできました。
原因は、以下の参考にした記事で解説されてあります。

$ sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

Password:
installer: Package name is macOS_SDK_headers_for_macOS_10.14
installer: Installing at base path /

installer: The install was successful.

Sprockets::Railtie::ManifestNeededError

標準ライブラリの sprocketsによって起きたエラーでした。

$ rails generate graphql:install
...
But did not, please create this file and use it to link any assets that need
to be rendered by your app:

Example:
  //= link_tree ../images
  //= link_directory ../javascripts .js
  //= link_directory ../stylesheets .css
and restart your server
