It’s more popular on Linux but is also used extensively on macOS. In fact, for apps that install as packages, Homebrew is the easiest way to remove them. Here’s how you can install Homebrew on macOS Catalina. In order to install Homebrew on macOS Catalina, you must have Xcode installed. You can get it from the Mac App Store.
To develop Flutter apps for iOS, you need a Mac with Xcode installed. Install the latest stable version of Xcode (using web download or the Mac App Store). Configure the Xcode command-line tools to use the newly-installed version of Xcode by running the following from the command line. Download Xcode for macOS 11.0 or later and enjoy it on your Mac. Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging. Learn about the key features available in Xcode, the integrated development environment for building apps for Mac, iPhone, iPad, Apple Watch, and Apple TV. Important - end of support for macOS 10.10 (Yosemite): Version 6.0.2 is the last to support macOS 10.10 (Yosemite). We strongly recommend upgrading to newer macOS version in order to receive further AnyDesk updates. This is how to install macOS Sierra on your desktop computer without a mac.
When you try to build xdebug on macOS Catalina you will get errors like these:
Configure and build xdebug on macOS Catalina
The reason for these errors is that the /usr/include folder is missing because Apple removed it when they released Xcode 11.
But, you can work around this problem. Here is how:
First, you need to make sure that Xcode and the command line tools installed. Open a terminal window and run the following command to display the SDK path:
This command should output something like this:
If not, install the command-line tools with executing:
and follow the instructions. After the installation is finished, start Xcode App to make sure the installation is done.
Now try to display the SDK-Path again:
The php tools needed to compile an extension try to use this missing include folder. We will create a modified version of phpize and php-config which will use the includes from the macOS SDK. First we will copy phpize and php-config and then we will modify these copies with a patch.
We create a new folder in your home directory under /Users/YOUR-USERNAME with the name 'php-private'..
Now copy phpize and php-config to php-private
Now determine which PHP version is installed on your system by executing
You should get something like this
I have prepared two patches to simplify the process. Download the two files and save them in your Downloads folder.
Download the phpize patch phpize-catalina.patch.zip and save it. The contents of the patch file for reference:
For PHP 7.3.9 Download the php-config patch php-config-7.3.9-catalina.patch.zip and save it.
For PHP 7.3.11 Download the php-config patch php-config-7.3.11-catalina.patch.zip and save it.
The contents of the patch file for reference:
Extract the compressed patch files.
PHP 7.3.9:
PHP 7.3.11:
Now we patching our copy of phpize and php-config
PHP 7.3.9:
PHP 7.3.11:
We are ready to compile xdebug
Create a working directory in your home folder. We will build xdebug here
Download xdebug from Xdebug.org and save in under Downloads.
Copy the archive to the working directory and extract it.
Now, we run our patched phpize in the xdebug folder.
When everything went good, you get something like this:
If so, you can skip the next part and continue with configuring and installing Xdebug.
Errors like these means, you need to install some requirements.
If phpize prints lines like these, you need to install autoconf:
To install autoconf, execute the following commands:
Now run our patched phpize in the xdebug folder again.
Check the output, and if everything went good, continue.
Configure and build xdebug:
Now we will find the full path to our patched php-config. This can be done like this:
Install Xcode For Mac Catalina Os
The output will something like:
Replace '/Users/YOUR-USERNAME/php-private/php-config' with the output of the above command and configure xdebug by executing:
In the output of configure you will see that the SDK path is being used:
Now build the extension
We don't executing 'make install' to install xdebug.so because the macOS System Integrity Protection (SIP) will not allow us to install xdebug to the /usr/lib/extensions folder. To workaround this, we install the extension under the /usr/local folder.
Now edit your php.ini (usually under /etc/php.ini) to load the right xdebug. PHP searches for extensions in its default extension directory. Our xdebug resides outside of this directory, so we have to specify the full path:
To test it, execute:
The output should begin like this:
Restart your apache web server to activate your changes
Mac OS X 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 OS X 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
If you have OS X 10.12 (Sierra) or older use this line instead
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.
Can't Install Xcode On Catalina
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 3 interpreter.
will launch the Homebrew-installed Python 2 interpreter (if any).
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.
Install Xcode-select Mac Catalina
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.
So, onward! To the Pipenv & Virtual Environments docs!
