No package found when invoking `carton dev` about carton HOT 14 CLOSED

BTW, the reason for carton considering swift-wasm-DEVELOPMENT-SNAPSHOT-2020-06-12-a the default is because it's a snapshot version that's known to work well. As soon as 5.3 snapshots are verified to be stable enough they will become the default in the next carton version.

This might be related to #65.

I had a similar issue with carton dev due to Xcode 12 beta 3 being selected.

It's related to command line tools selected? However I've changed to Xcode 11.6, the error still exists.

I also built and exported carton with Xcode 11.6, the error still exists too.

Did you try to run ~/.swiftenv/versions/wasm-DEVELOPMENT-SNAPSHOT-2020-07-02-a/usr/bin/swift package dump-package directly from the same directory? I wonder what the output of that would be.

from carton.

The response is:

➜  TokamakApp /Users/ziyuanzhao/.swiftenv/versions/wasm-DEVELOPMENT-SNAPSHOT-2020-07-02-a/usr/bin/swift package dump-package
/Users/ziyuanzhao/Documents/open-source-project/swiftwasm/TokamakApp: error: manifest parse error(s):
<unknown>

from carton.

I'm pretty sure it's unrelated to the Xcode version, it's related to problems with snapshots we experienced in the beginning of July described here swiftwasm/swift#1365. Does a more recent snapshot, swift-wasm-DEVELOPMENT-SNAPSHOT-2020-07-14-a for example, resolve the issue for you?

from carton.

Yep, this snapshot resolved the issue. But another occurs:

I've tried to delete the Package.resolved as the message told, but it doesn't work.

I can reproduce it locally, thanks for reporting this! Investigating now...

Sorry about directing you to a broken snapshot, I've just tried the latest 5.3 that you can download here in the "Artifacts" dropdown: https://github.com/swiftwasm/swift/runs/911478444?check_suite_focus=true

It works with that snapshot. Our latest development snapshots seem to be broken as you've reported and we don't have anything newer than that. wasm-5.3-SNAPSHOT-2020-07-26-a should be tagged tonight, it now has both Foundation and XCTest included, while previous 5.3 snapshots didn't. If you want to install it now, you can download macos-installable.zip from "Artifacts" and unpack it, you'll then have to copy the unpacked directory to ~/.swiftenv/versions manually. Or you can download the tagged version tomorrow more easily with carton sdk install. Hope that helps 🙂

By the way, was there anything that made you look for newer snapshots? The default wasm-DEVELOPMENT-SNAPSHOT-2020-06-12-a that carton uses by default right now should also work.

All right. Maybe I'll wait for a couple hours to use the latest tagged version and have another try.

It seems that carton now always download swift-wasm-DEVELOPMENT-SNAPSHOT-2020-06-12-a as default. Because of Chinese bad network situation, I have no idea to speed up downloading it with carton, even if I used VPN. But I found if I use swiftenv to download, the speed is acceptable. So I used swiftenv and always download the latest version.

from carton.

No problem at all, you're welcome to continue using swiftenv 🙂

With 5.3 builds I hope they are more stable on average than the previous development snapshots, that would mean there's less need to download newer snapshots once you're using the 5.3 branch. When Apple releases 5.3.0 later this year, I plan to tag SwiftWasm 5.3.0 and release patch versions after that, which overall should become even more stable.

from carton.

The release has been tagged and you can install it with carton sdk install wasm-5.3-SNAPSHOT-2020-07-26-a or swiftenv install https://github.com/swiftwasm/swift/releases/download/swift-wasm-5.3-SNAPSHOT-2020-07-26-a/swift-wasm-5.3-SNAPSHOT-2020-07-26-a-osx.tar.gz or whatever URL you pass to swiftenv to download the snapshot. Do any of these work well for you?

from carton.

It works now! Thanks a lot and I'm going to close this issue.

No problem, I'm glad it worked!
