MacでM5stack Core2 for AWS その２

Last updated at Posted at 2021-02-24

0. はじめに

前回はQiitaを書くのに疲れてしまい、
投稿はESP-IDFまでと中途半端に終わってしまったので
今回はLチカまで進めます。
ドキュメントはここのAWS CLIのインストールからです。

例によってエラーとの格闘です:ghost:

1. AWS CLIインストール

AWSアカウントも何もないところからだと、ちと面倒ですが、
ココを乗り越えないと先に進めませんので、
ドキュメント通りにAWSのアカウント作成、AWS CLIのインストール、
aws configureを行います

2. Minicondaインストール

ドキュメント通り進めます。
私はココのPython3.8のpkgをインストールしました。

ドキュメントにある、edukit環境作成とedukit環境への切り替えは
下の通りうまくいきました

(base) オレ@MacBook ~ % conda create -n edukit python=3.7

次に環境の移動

が、次のexport.shでまたコケました

Getting Started Guideを読みやがれと。。。
う〜ん、まあなんか

が怪しそうだな。。。と思いつつも先に進める。。。

3. デバイス証明書の取得と登録

(edukit) オレ@MacBookAir AWS_IoT_registration_helper %

なんかうまくいった模様
早速、デバイス証明書の取得と登録
シリアルデバイスは前のページと同じく
/dev/cu.usbserial-0225F023
を指定

(edukit) オレ@MacBookAir AWS_IoT_registration_helper % python registration_helper.py -p /dev/cu.usbserial-0225F023 
Pyserial is not installed for /Users/オレ/opt/miniconda3/envs/edukit/bin/python. Check the README for installation instructions.
Traceback (most recent call last):
  File "registration_helper.py", line 42, in <module>
    import esptool

During handling of the above exception, another exception occurred:

  File "registration_helper.py", line 49, in <module>
    import esptool
  File "/Users/オレ/esp/esp-idf/components/esptool_py/esptool/esptool.py", line 38, in <module>
    import serial
ModuleNotFoundError: No module named 'serial'

またエラー。。。
モジュールがないだけなので、何も考えずserialとesptoolをインストール！

〜〜〜まずはserial〜〜〜

こんなのがあったので、とりあえず

(edukit) オレ@MacBookAir Blinky-Hello-World % export IDF_PYTHON_ENV_PATH="/Users/オレ/opt/miniconda3/envs/edukit"
