cargo build failed

[banditkroot]

I've got this error when I tried to build.

$ cargo build --release --verbose
failed to parse registry's information for: serde_json
Caused by: the given version requirement is invalid

[serfma]

Came across the same issue. Few months later, but, did you by chance find a solution?

[banditkroot]

No.

Issue still exists. I'm trying to build on 16.04 and I think I've never built any other rust things as I had to install cargo to attempt the build in the first place.

Guess I'm off hunting on how to figure this out.

Version of Cargo in Ubuntu isn't new enough apparently. A lot more progress with latest from: https://www.rust-lang.org/en-US/install.html

[khyperia]

Thanks for the issue - I had no idea that people other than me and a friend were using this, so I apologize for not checking github issues for a long time.

I've never seen this error before. I'm guessing that the issue of cargo being too old in Ubuntu is related - it's recommended to use rustup to install rustc/cargo.

Alternatively, it might be just because the Ubuntu version of Cargo can't parse the checked-in version of cargo.lock. Try deleting that file and building - you may run into other issues (e.g. source incompatibilities due to versioning issues), but it may be a temporary workaround if it works.

Cool, that will be helpful for someone else finding the same issues :) Or me if I try to go back to other routes.

Not sure if I should create a new issue or not (technically not the same issue, but caused by the same thing). I had this issue too, setting up rustup solved that. However. I ended up seeing this instead. Using Ubuntu 16.04LTS:

weechat-discord needs weechat plugin header. It tries to get this header path with pkg-config.

• is pkg-config installed? If not sudo apt install pkg-config
• is a recent weechat installed? weechat -v to find weechat version
• pkg-config --cflags weechat return weechat header path. In my case (debian 9) /usr/local/include/weechat (It contains weechat-plugin.h)

[FredrIQ]

I'm on weechat 1.4. This is what the latter returns:

[2013][fiq@fiq ~/weechat-discord]$ pkg-config --cflags weechat
Package weechat was not found in the pkg-config search path.
Perhaps you should add the directory containing `weechat.pc'
to the PKG_CONFIG_PATH environment variable
No package 'weechat' found

$PKG_CONFIG_PATH is empty.

EDIT: Installing weechat-dev seems to have done the trick for that error, but I still have issues.

Is this a matter of my weechat version being too old?

[yfery]

Yep, your version seems too old. See ticket https://github.com/khyperia/weechat-discord/issues/23

[khyperia]

Probably should have reported a new issue in the general case, but in this case, that exact error has been reported twice now (three times if you count this report). Closing this issue since the original issue seems to have been resolved by upgrading cargo :smile:
