Updating to latest version of CocoaPods?

I'm having some issues installing Alamofire 4.0 into my project.

I've got the latest version of Xcode, running Swift 3, and when I try to install alamofire I'm getting like 800 compiler errors.

Apparently

CocoaPods 1.1.0+ is required to build Alamofire 4.0.0+

[!] some_cocoapod requires CocoaPods version >= X.Y.Z, which is not satisfied by your current version, Z.Y.X.

I looked at the version of CocoaPods I have in terminal and it says I'm at 1.0.1.

Running an update didn't work I guess because CocoaPods 1.1 is in beta.

So I'm not exactly sure how to update it up to where I'm good to go. Unless being out of date doesn't force like 800 compiler errors? Does that sound like some other issue?

Execute the following on your terminal to get the latest stable version:

sudo gem install cocoapods

Add --pre to get the latest pre release:

sudo gem install cocoapods --pre

If you originally installed the cocoapods gem using sudo, you should use that command again.

Later on, when you're actively using CocoaPods by installing pods, you will be notified when new versions become available with a CocoaPods X.X.X is now available, please update message.

Open the Terminal -> copy below command

sudo gem install cocoapods

It will install the latest stable version of cocoapods.

after that, you need to update pod using below command

pod setup

You can check pod version using below command

pod --version

If you got System Integrity Protection enabled or any other permission write error, which is enabled by default since macOS Sierra release, you should update CocoaPods, running this line in terminal:

sudo gem install cocoapods -n/usr/local/bin

After installing, check your pod version:

pod --version

You will get rid of this error:

ERROR:  While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory

And it will install latest CocoaPods:
