No module named pandas_datareader

问题

I have just installed pandas_datareader using pip install pandas-datareader which ran successfully.

Now I am trying to use it for a tutorial and I am getting this error when I try to import.

    import pandas_datareader as pdr

ModuleNotFoundError: No module named 'pandas_datareader'

This is the link to the tutorial.

Any ideas?

回答1:

Type into Terminal:

pip install pandas_datareader

That's it

回答2:

In your Anaconda Prompt, do this : pip install pandas_datareader

回答3:

All the other methods didn't work for me.

In command prompt: conda install -c delichon pandas_datareader

This is working fine on 22nd sept 2019 make sure to update pip.

Ok the following steps resolved the "No module named 'pandas_datareader" issue for me. To be clear, my situation was such that I had already installed pandas_datareader via pip install pandas_datareader but the "No module named 'pandas_datareader" error still kept popping up whenever I ran a .py code that imports pandas_datareader.

If you are in the same situation as I was (on Mac), this may help you.

Step 1: Uninstall the pandas_datareader package first:

• via terminal, type pip uninstall pandas_datareader
• it will prompt you asking for a y/n answer to proceed with the uninstallation
• type 'y'

Step 2: Restart your IDE if you were using one

• in my case, I was using MS VSC (Visual Studio Code)

Step 3:: re-install pandas_datareader package

• again via terminal, type pip install pandas_datareader

• your terminal may show you a bunch of "pre-installed" pandas_datareader package with message "Requirement already satisfied..."

• ignore those.

Step 4: Run your python code again

• the "No module named 'pandas_datareader" error should be gone this time round.

Hope this helps.

I had the same problem. I tried pip install pandas_datareader in my Anaconda Prompt and the problem was solved. For some reason, it didn't work in command prompt.

回答6:

Got this error even though I had pandas_datareader installed. Running on Windows. py -3 -m pip install pandas_datareader in the command prompt didn't work. Same in anaconda prompt didn't work. pip uninstall pandas_datareader followed by pip install pandas_datareader and a reboot finally fixed my problem.

TLDR if running on a Windows machine, uninstall pandas_datareader if you have it (pip uninstall pandas_datareader) and then reinstall with 'pip install pandas_datareader'.

Go to C:\Users\[UserName]\AppData\Roaming\jupyter\kernels\python3 and open up kernel.json. Check the first argument is pointing to a Python 3 environment/the environment you installed pandas_datareader to.
