OMG.....I just fixed the problem.Too many posting on the internet suggest the operation：gem install cocoapods --pre
But it doesn't work for me!
If you encounter the same probem likes me,try this

My xcode version is 9.3,so the project format settint would be :Xcode 9.3 - compatible
just select one under 9.3.
then pod install
fixed.....it works for me(confused 2 days),hope helps you guys!!!!!

@luckycherry Beijing coder says HELLO~

YouZoudeFish on 29 Jun 2018

I find that if gem sources use http://rubygems-china.oss.aliyuncs.com in cocoa pods only can update to v1.3.0.
If you gem sources use this, it must change to https://gems.ruby-china.org for latest version.
Then, just hit this on Terminal
sudu gem install -n /usr/local/bin cocoa pods --pre

Finally, It works!

Thx!
