Install Xcode Command Line Tools Catalina

Posted on by

Command Line Tools & Older Versions of Xcode. See the latest advances in Xcode presented at WWDC and other events. Help and Support. If you don’t intend to use ios. rules, it is sufficient to install the Xcode command line tools package by using xcode-select: xcode-select -install Otherwise, for ios. rule support, you must have Xcode 6.1 or later with iOS SDK 8.1 installed on your system. To update the CLT, go to app developer website and download the command line tool.dmg. If you have never installed Xcode before, you may be able to update with your Terminal by typing in xcode-select -install instead of visiting the developer website. Install Command Line Tools Open your terminal to begin the process of installing command-line tools on macOS Catalina. With your terminal opened, type the command below into the prompt and press the return key to execute it. After executing the command below a pop-up window should open with the option to install.

Recently, I have upgraded mac to 10.15.1 and I got a weird issue with node-gyp while working on my node project. It started failing when I was doing npm install. The issue reported was regarding the xcode-select CLT. We usually avoid installing full xcode and install the CLT (Command Line Tools) using xcode-select --install command.

Tried to run the command again but it did not work as CLT was already installed.

I did struggle for sometime to fix the issue. Finally, I found the solution and this is what I did.

  • Navigated to the folder /Library/Developer/ using terminal.
  • Removed the folder named CommandLineTools. Use sudo if needed.
  • Ran the command xcode-select --install which prompts for installing the command line toos. Once done, everything is back to normal for my node project.

Putting it here serves two purpose. One, It may help someone else and so won't hamper the productivity. Two, If there is another way to solve this issue, we can share it here through comment to let others know.

The latest version of Mac OS X, High Sierra, comes with Python 2.7 out of the box.

You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.

The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.

Doing it Right¶

Let’s install a real version of Python.

Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading XCode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.

Note

If you already have XCode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.

Note

If you perform a fresh install of XCode, you will also need to add thecommandline tools by running xcode-select--install on the terminal.

While OS X comes with a large number of UNIX utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.

To install Homebrew, open Terminal oryour favorite OSX terminal emulator and run

The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your PATH environment variable. You can do this by adding the followingline at the bottom of your ~/.profile file

Now, we can install Python 3:

This will take a minute or two.

Pip¶

Homebrew installs pip pointing to the Homebrew’d Python 3 for you.

Working with Python 3¶

At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.

will launch the homebrew-installed Python 2 interpreter (if any).

Install

will launch the homebrew-installed Python 3 interpreter.

If the Homebrew version of Python 2 is installed then pip2 will point to Python 2.If the Homebrew version of Python 3 is installed then pip will point to Python 3.

The rest of the guide will assume that python references Python 3.

Pipenv & Virtual Environments¶

The next step is to install Pipenv, so you can install dependencies and manage virtual environments.

A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.

For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.
