"no implicit conversion of nil into String" when logging in #190

jalanb · 2014-05-23T14:44:11Z

Just d/l and installed travis cli onto Ubuntu 12.0, with ruby 2.1

First command I tried it asked me to log in, but then:

$ GLI_DEBUG=true travis login --pro

BanzaiMan · 2014-05-23T14:58:42Z

This is weird. Login with GitHub failed, but the error's response body was nil.

https://github.com/travis-ci/travis.rb/blob/v1.6.11/lib/travis/tools/github.rb#L230

Does the error persist?

JoeKarlsson · 2017-10-19T14:49:27Z

Just ran into this issue, has anyone found a fix for this?

JoeKarlsson · 2017-10-19T15:26:51Z

For me, this was a firewall issue. Once I went to another network without a firewall, I was able to login to Travis with no issues.

KyeRussell · 2018-02-24T03:50:56Z

Is this still an issue for anyone else? I am experiencing it now - no firewall issues.

vijayenthran · 2018-02-24T04:11:08Z

Same issue here. Facing it now :( . @BanzaiMan , Can you please help

AlexSugak · 2018-02-26T11:00:32Z

Same issue here. Trying to login using github token.

wiep · 2018-02-28T14:28:21Z

I've the same issue. It doesn't matter if I use a github-token or username and password.

hancush · 2018-03-01T22:13:31Z

I had the same issue, but I solved it by upgrading to Ruby (from 2.0 to 2.3).

Not sure if it matters, but I was also using travis installed via Homebrew. I uninstalled that version and reinstalled as recommended with gem install travis -v 1.8.8 --no-rdoc --no-ri.

Got same error, is there any solution for this issue ?

blackcappedchickadee · 2018-03-07T19:47:33Z

I had the same exact issues as what have been reported since Feb 23 2018, including the same exact stacktrace.

Thanks to what @hancush called out:

gem install travis -v 1.8.8 --no-rdoc --no-ri

...did the trick for me. I'm now able to sign in!

I tried pretty much everything, with no luck. In the end I gave up and installed it using homebrew (brew install travis).

astromechza · 2018-03-10T15:01:52Z

I managed to workaround this by switching ruby versions. I was using ruby 2.0.0 and switched to ruby 2.3.3 with rbenv.

Serves me right for running such an old ruby.

@astromechza

I have just installed ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin16] on my MacBook via brew

same error as before.

But... travis try to use old ruby again...

An error occurred running `travis login`:

astromechza · 2018-03-12T07:40:11Z

@WuglyakBolgoink Travis is still linked to the old 2.0.0 gems I assume. You'll need to reinstall the travis gem so that it links to your current ruby version.

WuglyakBolgoink · 2018-03-12T09:03:07Z

@astromechza thank you! fully re'install travis was very helpful! now I see no errors during login.

ice1000 · 2018-03-20T17:20:21Z

Same here, and the cause is I'm using https_proxy env var.
Removing it resolves this.

stopsopa · 2018-04-01T23:05:04Z

same here:

ruby -v

travis -v
1.8.8

fongelias · 2018-04-03T02:12:08Z

I just spent forever and figured it out. There are a few gotchas that can prevent the whole thing from working. If you've installed it incorrectly once, you might run into this issue over and over again.

what I did (thanks to all the comments above) was:
Make sure that your computer does not have any trace of travis on it

make sure you have either an updated version of ruby (2.3.3 and above) either as your system default or on rbenv
make sure that travis is not installed on any version of ruby (run gem uninstall travis on each of the rbenv versions you've tried to install it on, you can use gem list to see if it is installed)
make sure that the binaries are all gone- both from your rbenv shims and your /usr/local/bin

Properly install travis to the correct version of ruby
I haven't tried this on the system version since I'm using rbenv, but:

make sure that your local ruby is 2.3.3 and above by using ruby -v
run gem install travis -v 1.8.8 --no-rdoc --no-ri to install travis to your local ruby version
run rbenv rehash to make sure that the shims are installed
run travis and look at the last line. It should have a path showing the ruby version you are using.

This worked for me, and I think that if everyone makes sure that their computer is not in a strange state, it should work for everyone else. Hope this helps!

ArcherN9 · 2018-04-03T10:25:30Z

Thanks @fongelias That worked for me! I did not have to follow the full guide though, just upgrading ruby via rvm and reinstalling travis did it.

For people who want to update ruby using rvm or brew, refer this link.

I guess this ticket could be closed. No?

jtontiwith · 2018-04-11T18:22:48Z

I installed the latest version of ruby with Homebrew brew install ruby and ran sudo gem install travis -v 1.8.8 --no-rdoc --no-ri and that worked for me. I didn't touch my system ruby install at /usr/bin/ruby.

pckilgore · 2019-04-14T00:59:38Z

Still seeing the error after following @fongelias 's instructions...

BanzaiMan · 2020-04-08T17:32:45Z

This should be fixed by 59ef981.
