生锈货物初始签名验证失败

Question

i try to use cargo init to init cargo manage system.

but i can't see the $HOME/.cargo dir generate.

and the shell show

macmatoMacBook-Air:rust kula$ cargo init
warning: signature verification failed for sources.json

macmatoMacBook-Air:rust kula$ cargo sync
error: No sources defined. You may wish to run "cargo init" then "cargo sync".

what's up on the cargo manage system?

my os is mac osx 10.7

Answer 1

cargo appears to shell out to GPG and use crappy regexes on the output. Which fails if your locale isn't what it expects. This worked for me:

LC_MESSAGES=C cargo init

Answer 2

The issue is likely that you don't have gpg installed so it can't verify the signature of cargo-central's source file, and then proceeds to not work at all.

This situation where signature verification fails is supposed to be non-fatal, but there was a bug in cargo that caused it to not complete the 'init' command.

I've checked in a change to cargo that I believe should allow it to continue even when signature verification fails, but FWIW cargo could use some love to make it more useful and reliable.
