PyCharm current working directory

问题:

Recently, I'm unable to use relative paths in my code while using PyCharm. For instance, a simple open('test.txt', 'r') will not work - whereupon I am sure the file exists in the same level as the running py file. PyCharm will return this error.

FileNotFoundError: [Errno 2] No such file or directory:

After reading answers online on StackOverflow, I have tried multiple options including:

• Changing test.txt to ./test.txt
• Closing project, deleting the .idea folder, open the folder with code.
• Reinstalling as well as installing the latest version of PyCharm.
• Invalidating caches and restarting.

None of these options have worked for me. Is there someway I can tell PyCharm to refresh the current working directory (or even to see where it thinks the current working directory is)?

Thanks in advance!

Edit: I should note that running the script in a terminal window will work. This appears to be a problem with PyCharm and not the script.

I have Pycharm 4.5, so things might have changed a bit.

Try going to Settings > Project > Project Structure

On this dialog, click your folder that has the source code in it, and then click the blue folder in the menu to note it as "source" folder. I believe this fixes a lot of the path issues in Pycharm

Here is the link to "content roots": https://www.jetbrains.com/pycharm/help/content-root.html

Change: Run > Edit Configurations > Working directory, which sets the working directory for a specific project. (This is on a Mac)

回答3:

__file__ refers to file path. So you can use the following to refer file in the same directory:

import os

dirpath = os.path.dirname(__file__)
filepath = os.path.join(dirpath, 'test.txt')
open(filepath, 'r')

Sometimes it is different. I solved my problem by clicking "Run" at the Pycharm's toolbar and then "Edit Configurations..." and I change my Interpreter to another actual one. Just changing it in the settings does not help, but this opperation already does ;)

回答5:

I too had the same issue few minutes ago...but,with the latest version of PyCharm it is resolved by simply using the relative path of that file.. For instance, a simple f = open('test', 'r') will work.

回答6:

In PyCharm, click on "run/edit configurations..."

Then find your script file in the "Python" dropdown menu. Check the "Working Directory" entry and change it if necessary.

A little clarification for mac users. In mac, what @andere said above is correct for setting working directory. However, if your code is in a different folder, say working_dir/src/ (like classic java/scala file structure) in that case you still need to set your Sources Root. In mac's PyCharm this can be done by right clicking on the src/ folder > Mark Directory as > Sources Root. Helped me with lot of similar import issues. Hope this helps someone.
