OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed about ruby-docs-samples

[blowmage]

This is a common error when ruby is missing the needed SSL certificate configuration. Most ruby installers will add this configuration, but it looks like your install is missing it. The easiest way to resolve this is to check for a SSL_CERT_FILE environment variable. If it is missing, then adding it (and the certificate file it points to) should fix this.

Here are some Stack Overflow questions that may help

Thanks @blowmage!

@niaomingjian What did you use to install Ruby on your machine?

@remi I used RubyInstaller to install Ruby 2.3.1.

I tried those solutions before, but they didn't work.

I tried again., downloaded SSL certificate(cacert.pem), put it in Ruby23-x64\lib\ruby\2.3.0\rubygems\ssl_certs directory and set SSL_CERT_FILE environment variable.

Though I could install jekyll successfully, running this datastore example still got that error.

Even I uninstalled Ruby and reinstall it again. I still can't solve this problem.

Can you post the full backtrace? Datastore uses GRPC to connect to the API, but the error you are reporting is coming from Faraday, and I'm not sure what is using Faraday.

What version of google-cloud are you using?

@niaomingjian can I close this issue? Not sure if this is still an issue moving forward.
