Windows Subsystem for Linux(WSL)上にVagrant環境を構築する際は、gccとmakeを必ずインストールするべし

f:id:yokoyantech:20190125173930p:plain

はじめに

Windows Subsystem for Linux(WSL)上にVagrant環境を構築して、vagrant-awsプラグインをインストールしようとしたら大ハマリしたのでメモ。

実行環境

  • Windows 10 64bit(ver 1803)
    • Windows Subsystem for Linux(WSL)
      • Ubuntu 18.04.1 LTS (Bionic Beaver)
      • Vagrant 2.2.3

やりたいこと

  • WSL上で起動するVagrant環境にvagrant-awsを入れたい

結論

タイトルのとおりです。

Windows Subsystem for Linux(WSL)上にVagrant環境を構築する際は、gccmakeを必ずインストールするべし。

以下、ハマった軌跡です。

発生したエラー

$ sudo vagrant plugin install vagrant-aws を実行したら下記のエラーが発生。

$ sudo vagrant plugin install vagrant-aws

Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:

ERROR: Failed to build gem native extension.

エラー解析

mkmf.logの確認

  • 発生したエラーに記載されているログファイルを確認。
  • gcc: not foundとのこと。

2:

/* end */

gccコマンドの確認

  • 試しにgccを実行してみる。確かにコマンドがない。
$ gcc

Command 'gcc' not found, but can be installed with:

sudo apt install gcc

処置

gccコマンドのインストール

$ sudo apt-get update
$ sudo apt install gcc

gccコマンドの実行

  • 今度はOK
$ gcc
gcc: fatal error: no input files
compilation terminated.

再度vagrant-awsのインストール

$ sudo vagrant plugin install vagrant-aws

今度はエラーが変わった。

確かにmakeコマンドがない。

$ make

Command 'make' not found, but can be installed with:

sudo apt install make
sudo apt install make-guile

処置2

makeコマンドのインストール

$ sudo apt install make
$ sudo apt install make-guile

3度目のvagrant-awsのインストール

  • やっと入ったー!!!
$ sudo vagrant plugin install vagrant-aws

# 略

Fetching: vagrant-aws-0.7.2.gem (100%)
Installed the plugin 'vagrant-aws (0.7.2)'!

まとめ

nokogiriが悪いと言うより、WSLの罠にハマってしまいました。 エラーメッセージをちゃんと読めば、トラブルシューティングできるなと痛感しました。

焦っていろいろググる前にまずエラーメッセージを読むべし!
