The first time I used wandb login from the command line, I encountered the error PermissionError: [Errno 13] Permission denied: ‘/tmp/.config/wandb/’. However, I have checked that the permissions on the /tmp folder are: “rwxrwxrwt”, and I can also create new files in /tmp. I hope i can get the answer about the permission of the tmp file. Later, using the developer guide, I temporarily solved this problem by using os.environ[“WANDB\_CONFIG\_DIR”] = op.join (OS.getcwd (),“tmp”) in my py file. However, I didn’t want to add such a paragraph to my script every time, so I tried adding environment variables to the.bashrc file. However, when I source.bashrc, “WANDB\_DIR: command not found” is displayed. I am also looking forward to your answer on how to correctly set environment variables ---

Hi @matrixmax, is `tmp/` the root directory on this machine? That config file should normally end up in `~/.config/wandb/settings` unless this path is unwritable. It may be worth figuring out why wandb doesn’t have access to write to `~/` Also, could you let me know how you were attempting to set this in your bashrc? ---

Thank you very much for your reply, the “tmp” directory I mentioned is the root directory of the system, namely: the “/tmp” folder. Do you mean that I should check the permissions for the “~/.config/” folder? Okay, I’ll go back and try The Settings in.bashrc are shown in the following figure. The directory used was the tmp folder I created in my own home directory. ![Snipaste_2023-09-19_10-04-25](https://us1.discourse-cdn.com/flex020/uploads/wandb/original/2X/e/e4348ca8a2724171174be6606b1185a17f918dfe.png) ---

Hello! It looks like Python doesn’t have permissions to write to the `.config/wandb file` and you probably need to use `chmod` to update the permissions. Have you checked the permissions for the “~/.config/” folder and were you able to fix this issue after changing the permissions? ---

Thank you very much for your reply! I have checked that the permissions for the “~/.config/” directory are: `drwxrwxr-x 10 wxl wxl 10 Sep 19 10:03 .config/` , and the permissions of the “/tmp” directory are: `drwxrwxrwt 3970 root root 159744 Sep 27 11:06 tmp/` But that still doesn’t solve the problem ---

Could you try to make a new environment or try a separate environment to try this in? We do not have any known permissions issues on our end and all the signs seem to point to this being an environment-based permission issue. Hopefully this can be solved with a different environment since it purely looks like your current environment is having issues. ---
