Python Pandas "Error: Could not install packages due to an OSError: No such file or directory:"

Question

System:Win10
IDE: VSCode
Python path: C:\Users\user\AppData\Local\Continuum\miniconda3

while trying to install pandas and geopandas via VSCode terminal to run Jupyter Notebook, I encountered issues, so I created a conda environment and installed pandas and geopandas via Command Prompt and they were successful. Now the Jupyter Notebook worked, by my pythonfiles.py) on VSCode can't find pandas.

> PS C:\Users\user\folder> python pythonfile.py
> Traceback (most recent call last):   File
> "pythonfile.py", line 1, in <module>
>     import pandas as pd ModuleNotFoundError: No module named 'pandas'
> 

when I check "pip list" in VSCode, resulted:

seems pandas and geopandas are installed in the environment, however, running the pythoncode.py still returned:

> Traceback (most recent call last):   File
> "C:\Users\user\folder\pythonfile.py", line 1, in <module>
>     import pandas as pd ModuleNotFoundError: No module named 'pandas'
> 

when I return to VSCode and try to install pandas again, I get the following error:

> PS C:\Users\user\folder> pip install pandas Collecting pandas

how can I make pandas and geopandas work ?

Answer 1

The reason is that the python used by the internal terminal of VS Code is different from the python environment you currently select in VS Code (shown in the lower left corner of VS Code).

I noticed that you are using the powershell terminal, which does not automatically activate the conda environment by default in VS Code.

1. Please select conda environment in VS Code, it will be displayed in the lower left corner of VS Code. (F1, Python: Select Interpreter)

2. Please enter "Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process" in the VS Code terminal, and then reopen the VS Code terminal (Ctrl+Shift+`). When using the command "python --version", the python version it displays is the same as the one displayed in the lower left corner.

   

3. If the module is not installed in this environment, please follow it. (pip install pandas)

Update:

In addition, please try to use other terminals, such as the 'cmd' terminal. Can I use Cmder's shell with the terminal on Windows?
