当我生成一个新的rails应用程序时，我会得到这个错误

Question

Fetching source index from https://rubygems.org/
Retrying source fetch due to error (2/3): Bundler::Fetcher::CertificateFailureError Could not verify the SSL certificate for rubygems.
There is a chance you are experiencing a man-in-the-middle attack, but most likely your system doesn't have the CA certificates needed for verification. For information about OpenSSL certificates, see bit.ly/ruby-ssl. To connect without using SSL, edit your Gemfile sources and change 'https' to 'http'.

         run  bundle exec spring binstub --all

我运行了gem update --system，但是它不起作用。我又犯了一个错误：

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)

这是怎么回事，我该怎么解决呢？谢谢

Answer 1

此问题通常发生在旧版本的rubygem中。您可以尝试通过运行

gem update --system --source http://rubygems.org/

在那之后

gem update

来源。

Answer 2

在主目录中创建一个新文件.gemrc并添加这一行。

:ssl_verify_mode: 0

现在，即使无法验证SSL连接是“可信的”，它也应该继续。
