升级到 xcode9.0 之后使用 安装cocoapods 会出现如下情况:
Air:~ Jniying$ sudo gem install cocoapods
Password:
YAML safe loading is not available. Please upgrade psych to a version that supports safe loading (>= 2.0).
ERROR: Could not find a valid gem 'cocoapods' (>= 0), here is why:
Unable to download data from https://gems.ruby-china.org/ - Errno::ECONNREFUSED: Connection refused - connect(2) (https://gems.ruby-china.org/specs.4.8.gz)
YAML safe loading is not available. Please upgrade psych to a version that supports safe loading (>= 2.0). 这个是什么鬼??

Try `brew tap --repair` and make sure `brew doctor` looks reasonable.

表示好难过 更新不了rudy 就 安装不了cocoapods
新大陆: Try brew tap --repair and make sure brew doctor looks reasonable.
尝试一下 这个两个命名:
brew doctor

==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
/usr/local/etc/openssl/certs
and run
/usr/local/opt/openssl/bin/c_rehash
This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.
If you need to have this software first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include
==> Summary
🍺 /usr/local/Cellar/openssl/1.0.2n: 1,792 files, 12.3MB
