Anaconda3 × Pycharm environment construction memo

Python de amateur built the environment with Anaconda3 and Pycharm. I will leave it as a memorandum.

◆ Environment
◆ Flow of environment construction

First, install Anaconda and Pycharm Community. Conducted by referring to the here page. Execution is completed up to Hello World without any trouble.

python


ModuleNotFoundError: No module named 'openpyxl'

In the execution environment, openpyxl is already installed, and if you import openpyxl from the command prompt, you can execute it without any problem.

・ Cause In the execution environment used in Pycharm (strictly speaking, an Excel processing project created on Pycharm), openpyxl was not installed (in Pycharm (or Python?), Each project has a virtual execution environment individually. You can have it. You can reuse one virtual execution environment).

・ Countermeasures Solved by creating a virtual environment with Anaconda Navigator and installing openpyxl there. image.png

・ Countermeasures (detailed procedure)

  1. Launch Anaconda Navigator
  2. Click Create ("+" button)
  3. Select NaturalLanguage01 for "Name" and Python3.8 for "Packages" and click "Create" image.png
  4. Select "All" in the drop-down list and enter "anaconda" in the search box image.png
  5. Check "anaconda" and click "apply"

It looks like it should be a countermeasure ... w

The above procedure creates a virtual execution environment for Anaconda with "openpyxl" installed (as a result). You will need the path of the virtual execution environment created here later.

Next, in Pycharm, add an interpreter that specifies this execution environment.

  1. Start Pycharm and open "File"-> "Settings"-> any project (this time "Project: sampleOpenPyExcel")-> "Python Interpreter"
  2. Click the gear icon at the top right of the screen → "Add" image.png
  3. Click "System Interpreter" → Click "..." at the top right of the screen
  4. Find and select "Python.exe" directly under the virtual execution environment created by Anaconda, and click "OK". image.png
  5. Close the "Settings" window and click "run" → "Edit Configrations"
  6. Select the program file to which you want to apply the environment, select "Environment"-> "Python Interpreter", select the virtual execution environment you added earlier, and click "OK". image.png

This completes the settings. It was also possible to import the library.
