Describe the bug

Upon downloading the template, I'm unable to run pnpm dev in apps/expo. I receive the following permissions error due to the .gitignore:

Starting Metro Bundler
Error: EACCES: permission denied, open '/home/learning-projects/t3-test/apps/expo/.gitignore'

same issue here and don want to execute with sudo

Hi, I had the same issue. It looks like the .gitignore file gets generated without any rwx permissions. I fixed the issue by deleting the file and creating an empty /apps/expo/.gitignore file. The file should get updated automatically once you run pnpm dev again.

[juliusmarminge]

Can you please verify that this doesnt happen on a normal expo app? I dont see why this would be a cause of t3 turbo so this issue should likely be opened upstream?

[AMayer1997]

It works for me with a normal expo app. An intact .gitignore file gets generated with the cli: npx create-expo-app my-app.

btw thanks for your open source contributions

And if you delete that file and run pnpm dev again? I'm guessing that the create-expo cli is copyinh some template file at init with proper permisssions but then the dev server writes with different ones?

[AMayer1997]

I deleted the .gitignore file and it does not get generated again. I used npm run ios instead of pnpm dev, because the default expo app comes with npm.

I want to report I have the same issue and I fix the issue by adding file permissions to the .gitignore and running pnpm run dev

I can confirm that this is not a unique T3 issue, I get the same in an NX monorepo

[adamspotlite]

Does anyone know where to put this then? I feel like the proper steps are:

1. Close this issue
2. Make a note somewhere that there is a solution to the solution (namely, running chmod 644 apps/expo/.gitignore)
3. Add a new issue in one of the expo-cli repos

Is there anything wrong with just manually adding a .gitignore file to the expo directory as @AMayer1997 mentioned here

@psycho-baller not that I can tell - I think that's likely what most folks end up doing (myself included), without any downstream implications.

@juliusmarminge should i go through with this? I don't think this needs to be an active issue, but I feel it should be documented for future reference.

[juliusmarminge]

I opened an issue right after expo started generating gitignore that got converted to discussion (see expo/router#846)

I bumped that to see if they want a new issue or not. Either way I think we can keep this issue open just for visibility until they have fixed it on there part.

Happening to me as well

go to apps/expo/ and run following command. I will suggest 2nd one because it worked for me.

1. icacls .gitignore /grant %username%:F
   or
2. attrib -r .gitignore

[CarlosZiegler]

Tested right now and have same issue :)

[recallwei]

Try to delete the .gitignore file generated by Expo, then rerun.

[CarlosZiegler]

Then cli create new again

[swebreza]

try this
attrib -r .gitignore

[CarlosZiegler]

Works if use sudo, but this is not a solution :(

Linux user here.
Solved by
cd apps/expo
chmod 777 .gitignore

In my case, the .gitignore also cannot open in visual studio code.
So I did this and the issue gone:

• Remove the not openable .gitignore
• Create a new empty .gitignore file
• Run npx expo start

btw, here is the common content of .gitignore, you can paste it to empty file:
