grpcのライブラリが見つからないようである

原因

どうも最新のnode（v7系全般？）だとNGらしい

解決方法

nodeのバージョンを下げる

• nvmのインストール

git clone https://github.com/creationix/nvm.git ~/.nvm 
cd ~/.nvm
git checkout `git describe --abbrev=0 --tags`
. ~/.nvm/nvm.sh

• nvmの設定

下記を.bashrcなどに記述しておく

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"

• versionを下げる

nvm install 6.9.1

• もう一度、ビルドコマンドを実行

sudo lerna bootstrap 

補足

本エラーはcomposer-fabricに限ったことではなく、7系のNodeを使っている状態でgrpc@1.0.0をnpm installしようとすると出てくると思われる
