Dart pub publish gives error after authentication

Question

I wanted to put a small library code to pub.dartlang.org After calling pub publish, it asked me to Allow accessing my google account for sending files. After I allowed by going to the given browser link, it gave me this error in the command line:

Waiting for your authorization...
Authorization received, processing...
ProcessException: No such file or directory
Command: curl --dump-header /tmp/temp_dir1_CzMqQG/curl-headers --cacert /home/afsina/apps/dart/dart-sdk/util/pub/curl/ca-certificates.crt --request POST --location --max-redirs 5 --data-binary @- --header accept:  --header user-agent:  --header Content-Type: application/x-www-form-urlencoded; charset=UTF-8 --header content-length: 265 https://accounts.google.com/o/oauth2/token

here is the --verbose output

I am guessing it cannot find the ca-certificates.crt file but not sure why.

Answer 1

If you run pub on Linux or Mac, it will assume curl is in your PATH and try to spawn it without an explicit path. On Windows, it will use the included curl binary. Our assumption here was that most *NIX users would have curl installed already.

This curl dependency should be going away soon anyway, but I'm glad you found the solution.

Answer 2

My bad, this was because pub has "curl" dependency. After installing curl I could publish the lib.
