[Python]PyAutoGUIのインストールで躓いた話

Pythonでスクリーンショットを保存したく、PyAutoGUIをインストールしようとしたところエラーが発生し、解決に至るまでやったことをメモします。

論理的なことや正確さは考慮していないため、 必要ない操作がある可能性はあります。

※ただ、Selenium動作中にスクリーンショットを取得したかったので、別の方法でスクリーンショットを保存するようにしました。

参考

背景

画層の生成を行いたく、以下のコードを実行しようとしました。

例として、「01t.py」というファイルに以下のコードを実装。

import pyautogui
s = pyautogui.screenshot()
s.save('screenshot1.png')

実行したときのエラーと対応

$ python 01t.py
Traceback (most recent call last):
  File 01t.py, line 1, in <module>
    import pyautogui
ImportError: No module named pyautogui

→pyautoguiがない、といわれる。
　なので、インストールする

→PILがない、といわれる。
　まあ、言われた通りインストールする

　この状態でpyautoguiを使おうとしても状況は変わらなかった。
グーグルでいろいろ調べて試してみる。。。
