Catalina and Python Package Problems

I'm attempting to get a working version of python3 installed on a mac running Catalina (10.15.7).Calling python3 from the terminal ultimately errors with a software not available message. I've seen this problem already noted on this forum. Installing Homebrew installs CLT as well, and a python3 version in /usr/local/bin (version 3.9). I can then install numpy with pip3, but I cannot install scipy, which kicks up about 800 lines of error starting with openblas issues. Has anyone successfully installed scipy with Catalina? If so, how?

Get the Flutter SDK

Hi, The xcrun tool allows me to invoke the correct compiler and other tools for cross-compiling to, for example, iOS or the simulator. The -sdk flag lets me choose which SDK I want, such as -sdk iphonesimulator or -sdk iphoneos However, once I installed the Xcode 'command line tools', it seems like xcrun can only find the sdk for macOS.
Introducing Xcode 12. With an all-new design that looks great on macOS Big Sur, Xcode 12 has customizable font sizes for the navigator, streamlined code completion, and new document tabs. Xcode 12 builds Universal apps by default to support Mac with Apple Silicon, often without changing a single line.

Get the Flutter SDK

Download the following installation bundle to get the lateststable release of the Flutter SDK:
For other release channels, and older builds,see the SDK releases page.
Extract the file in the desired location, for example:
If you don’t want to install a fixed version of the installation bundle, you can skip steps 1 and 2. Instead, get the source code from the Flutter repoon GitHub with the following command:
You can also change branches or tags as needed.For example, to get just the stable version:
Add the flutter tool to your path:
This command sets your PATH variable for thecurrent terminal window only.To permanently add Flutter to your path, seeUpdate your path.
Optionally, pre-download development binaries:
The flutter tool downloads platform-specific development binaries asneeded. For scenarios where pre-downloading these artifacts is preferable(for example, in hermetic build environments,or with intermittent network availability), iOSand Android binaries can be downloaded ahead of time by running:
For additional download options, see flutter help precache.

You are now ready to run Flutter commands! Mac os lion download for pc.

Note: To update an existing version of Flutter, see Upgrading Flutter.

Run flutter doctor

Run the following command to see if there are any dependencies you need toinstall to complete the setup (for verbose output, add the -v flag):

This command checks your environment and displays a report to the terminalwindow. The Dart SDK is bundled with Flutter; it is not necessary to installDart separately. Check the output carefully for other software you mightneed to install or further tasks to perform (shown in bold text).

For example:

The following sections describe how to perform these tasks and finish the setupprocess.

Once you have installed any missing dependencies, run the flutter doctorcommand again to verify that you’ve set everything up correctly.

Warning: The flutter tool uses Google Analytics to anonymously report feature usage statistics and basic crash reports. This data is used to help improve Flutter tools over time.

Flutter tool analytics are not sent on the very first run. To disable reporting, type flutter config --no-analytics. To display the current setting, type flutter config. If you opt out of analytics, an opt-out event is sent, and then no further information is sent by the Flutter tool.

By downloading the Flutter SDK, you agree to the Google Terms of Service. Note: The Google Privacy Policy describes how data is handled in this service.

Moreover, Flutter includes the Dart SDK, which may send usage metrics and crash reports to Google.

Update your path

You can update your PATH variable for the current session atthe command line, as shown in Get the Flutter SDK.You’ll probably want to update this variable permanently,so you can run flutter commands in any terminal session.

The steps for modifying this variable permanently forall terminal sessions are machine-specific.Typically you add a line to a file that is executedwhenever you open a new window. For example:

Determine the directory where you placed the Flutter SDK.You need this in Step 3.
Open (or create) the rc file for your shell.Typing echo $SHELL in your Terminal tells youwhich shell you’re using.If you’re using Bash,edit $HOME/.bash_profile or $HOME/.bashrc.If you’re using Z shell, edit $HOME/.zshrc.If you’re using a different shell, the file pathand filename will be different on your machine.
Add the following line and change[PATH_TO_FLUTTER_GIT_DIRECTORY] to bethe path where you cloned Flutter’s git repo:
Run source $HOME/.<rc file>to refresh the current window,or open a new terminal window toautomatically source the file.
Verify that the flutter/bin directoryis now in your PATH by running:
