とりあえずserverlessでpythonを試してみる
npmのインストール
なんかインストール方法が複数あるっぽいけど、
nodebrewというのを入れるのがよさげだったのでそれにしてみる。
（会社のmacにはanyenvというのが入っていた）
http://www.hirooooo-lab.com/entry/development/install-node
brew install nodebrew nodebrew ls-remote nodebrew install-binary v6.9.4
インストールに失敗した。
% nodebrew install-binary v6.9.4 Fetching: https://nodejs.org/dist/v6.9.4/node-v6.9.4-darwin-x64.tar.gz Warning: Failed to create the file Warning: /Users/kubotad/.nodebrew/src/v6.9.4/node-v6.9.4-darwin-x64.tar.gz: No Warning: such file or directory curl: (23) Failed writing body (0 != 941) download failed: https://nodejs.org/dist/v6.9.4/node-v6.9.4-darwin-x64.tar.gz
ディレクトリを作ったらうまく行った。おかしい。
mkdir -p ~/.nodebrew/src % nodebrew install-binary v6.9.4 Fetching: https://nodejs.org/dist/v6.9.4/node-v6.9.4-darwin-x64.tar.gz ######################################################################## 100.0% Installed successfully
パスを通す。
echo 'export PATH=$PATH:~/.nodebrew/current/bin' >> ~/.zshrc % source ~/.zshrc % nodebrew use v6.9.4 use v6.9.4
バージョン確認
% node -v v6.9.4 % npm -v 3.10.10
https://nodejs.org/
から.pkgをダウンロードしてインストールでもいいような気がする。
anyenvのndenvの場合
インストール可能バージョンの一覧
ndenv install -l
# install ndenv install v6.9.4 # installed list ndenv versions # switch ndenv global v6.9.4
serverlessのインストール
# Install serverless globally npm install serverless -g

のトップページに載っていたコマンドを入力してみる。
serverless create --template aws-nodejs % ll total 24 drwxr-xr-x 5 kubotad staff 170 1 12 14:47 ./ drwx------@ 10 kubotad staff 340 1 12 01:10 ../ -rw-r--r-- 1 kubotad staff 86 1 12 01:10 .npmignore -rw-r--r-- 1 kubotad staff 466 1 12 01:10 handler.js -rw-r--r-- 1 kubotad staff 2410 1 12 01:10 serverless.yml
とりあえずインストールできた。
デプロイ
AWS IAMでアクセスキーを作成。

serverless config credentials --provider aws --key AKIAIOSFODNN7EXAMPLE --secret wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

IAM権限の設定でエラーが出て直らなかったので、
AdministratorAccess

% serverless deploy
を実行したら、エラーが出ずにデプロイできた。
