使用Expo SDK 25.0.0构建iOS企业版应用遇问题求助

Hey there, let's work through your Expo build problems step by step — I've dealt with similar headaches back when SDK 25 was still in active use, so here's what you should check:

1. Fix Your Command Syntax First #

The command you're running has a couple of errors that are definitely causing issues:

• You don't need the EXPO - prefix — just run exp fetch:ios:certs directly.
• The second command has an incorrect colon: it should be exp build:ios, not exp: build:ios.
• Also, make sure you're using English quotation marks (not the curly ones in your original command) or omit them entirely.

Correct command sequence:

exp fetch:ios:certs && exp build:ios

2. Fix Invalid app.json Configuration #

Your app.json has a broken value in the splash section that will crash the build process:

"resizeMode": "cover..."

That trailing ellipsis makes the JSON invalid. Replace it with a valid resize mode like "cover" or "contain", and double-check that all brackets and commas are properly closed. Here's the corrected snippet:

"splash": {
  "image": "./app/assets/AppName.png",
  "resizeMode": "cover"
}

3. Verify Enterprise Account & Certificate Selection #

Since you're using an Apple Enterprise account:

• When running exp fetch:ios:certs, explicitly select the enterprise distribution option when prompted. Expo may default to standard App Store distribution if you don't specify, which won't work for enterprise builds.
• Log into the Apple Developer Portal and confirm none of your enterprise certificates or provisioning profiles are expired or revoked. Expired assets will block the build.

4. Install a Compatible Expo CLI Version #

SDK 25 is extremely outdated (released in 2018), and the latest Expo CLI versions don't support it. You need to install a CLI version that's compatible with SDK 25:

npm install -g expo-cli@2.21.2

This specific version is known to work reliably with SDK 25. After installing, re-run exp login to ensure you're authenticated with your enterprise admin account.

5. Clear Cache and Rebuild #

Cached data can cause unexpected issues with older SDK versions. Clear Expo's local cache first:

exp start --clear

Then re-run the certificate fetch and build commands. Make sure you're executing these from the root directory of your Expo project.

6. Check Build Logs for Exact Errors #

If the build still fails, don't skip the build logs! When you run exp build:ios, Expo will provide a URL to view detailed logs. Look for lines marked error — they'll tell you exactly what's wrong (e.g., certificate mismatch, missing dependencies, invalid configuration).
