macOS 10.14(beta) How to install Command_Line_Tools_macOS_10.14_for_Xcode_10_Beta

Question

As the Title of my question, I don't know how to install the Command_Line_Tools_macOS_10.14_for_Xcode_10_Beta for my mac, please help.

What I did:

1. run command "brew install carthage" to install the Carthage, get errors:

Error: Your Xcode (9.4.1) is too outdated. Please update to Xcode 10.0 (or delete it). Xcode can be updated from https://developer.apple.com/download/more/

2. run command "xcode-select --install" in Terminal as the second answer from @Dev, but I still get the same errors after "brew install carthage";

3. download the .dmg file from Apple site, I got too many tools after I opened it:

I've tried install the two .pkg which marked with red rectangle in the attached image, but the error still coming.

Environment:

macOS 10.14 Beta
Xcode(Installed 2 versions on the Mac): 
10 (Beta), 
9.4.1

Answer 1

It looks like you have two versions of the xcode installed on your machine. First select the latest version of the xcode by running this command:

sudo xcode-select -switch <path/to/>Xcode.app

Once this is done, install the required command line tools but running this command:

xcode-select --install

Answer 2

This worked for me:

1. Download "Xcode 10.0 Beta" from https://developer.apple.com/download/
2. Unzip it and move it to /Applications
3. Download "Command Line Tools (macOS 10.14) for Xcode 10 Beta" from https://developer.apple.com/download/more/
4. Run the installer for "Command Line Tools"
5. Launch the Xcode-beta application and wait for it to install necessary packages when it prompts it at launch
6. Run this from the command line sudo xcode-select -switch /Applications/Xcode-beta.app/

Now brew update should work again.

Answer 3

This fixed things for me, on a fresh 10.14 Beta 3 install.

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

Answer 4

Following worked for me:

After you updated to Mojave 10.14 Go to https://developer.apple.com/download/more/ search for "command line" then

download "Command line tool for MacOS 10.14"

Once dmg is downloaded install the package.

Verify package installation
