I recently updated to macOS Catalina and encountered several issues with programs that use a C/C compiler.If you see any of these errors.
Print instructions for setting up the command-not-found hook for your shell. If the output is not to a tty, print the appropriate handler script for your shell. Services subcommand Manage background services with macOS’ launchctl(1) daemon manager. If sudo is passed, operate on /Library/LaunchDaemons (started at boot).

Question or issue on macOS:

After the instance I want to apply this command: brew cask install. I am running macOS Catalina v10.15.7. (Mac) -bash: gitps1: command not found.

I have installed Android SDK and Eclipse on my Mac system. I am able to program using Eclipse and have created few sample applications. But I am still not able to access adb through the terminal window. I have tried following command in terminal:

I have also added the ls output so that you know in which window I am.

How to solve this problem?

Solution no. 1:

The problem is: adb is not in your PATH. This is where the shell looks for executables. You can check your current PATH with echo $PATH.

Bash will first try to look for a binary called adb in your Path, and not in the current directory. Therefore, if you are currently in the platform-tools directory, just call

The dot is your current directory, and this tells Bash to use adb from there.

But actually, you should add platform-tools to your PATH, as well as some other tools that the Android SDK comes with. This is how you do it:

Find out where you installed the Android SDK. This might be (where $HOME is your user’s home directory) one of the following (or verify via Configure > SDK Manager in the Android Studio startup screen):
- Linux: $HOME/Android/Sdk
- macOS: $HOME/Library/Android/sdk
Find out which shell profile to edit, depending on which file is used:
- Linux: typically $HOME/.bashrc
- macOS: typically $HOME/.bash_profile
- With Zsh: $HOME/.zshrc
Open the shell profile from step two, and at the bottom of the file, add the following lines. Make sure to replace the path with the one where you installed platform-tools if it differs:
Save the profile file, then, re-start the terminal or run source ~/.bashrc (or whatever you just modified).

Note that setting ANDROID_HOME is required for some third party frameworks, so it does not hurt to add it.

In addition to slhck, this is what worked for me (mac).

To check where your sdk is located.

Open Android studio and go to:

File -> Project Structure -> Sdk location

Copy the path.
Create the hidden .bash_profile in your home.
(open it with vim, or open -e) with the following:

Then simply use this in your terminal: . ~/.bash_profile

Quick Answer

Pasting this command in terminal solves the issue in most cases:

** For Current Terminal Session:

(in macOS)export PATH=”~/Library/Android/sdk/platform-tools”:$PATH
(in Windows)i will update asap

** Permanently:

(in macOS) edit the ~/.bash_profile using vi ~/.bash_profile and add this line to it: export PATH=”~/Library/Android/sdk/platform-tools”:$PATH

However, if not, continue reading.

Detailed Answer

Android Debug Bridge, or adb for short, is usually located in Platform Tools and comes with
Android SDK, You simply need to add its location to system path. So system knows about it, and can use it if necessary.

Find ADB’s Location

How To Install Homebrew On Mac Catalina

Path to this folder varies by installation scenario, but common ones are:

If you have installed Android Studio, path to ADB would be: (Most Common)
(in macOS)~/Library/Android/sdk/platform-tools
(in Windows)i will update asap

If you have installed Android Studio somewhere else, determine its location by going to:
Diploma simulation lab manual pdf. By this perspective we have introduced a Laboratory manual cum Observation for Electrical Circuits and Simulation. The manual uses the plan, cogent and simple language to explain the fundamental aspects of Electrical Circuits and Simulation in practical. The manual prepared very carefully with our level best. Diploma electrical simulation lab manual can be one of the options to accompany you following having other time. It will not waste your time. Undertake me, the e-book will totally make public you.
- (in macOS)Android Studio > Preferences > Appearance And Behavior > System Settings > Android SDK and pay attention to the box that says: Android SDK Location
- (in Windows)i will update asap

However Android SDK could be Installed without Android studio, in this case your path might be different, and depends on your installation.

Add it to System Path

When you have determined ADB’s location, add it to system, follow this syntax and type it in terminal:

(in macOS)
export PATH=”your/path/to/adb/here”:$PATH
for example: export PATH=”~/Library/Android/sdk/platform-tools”:$PATH

Solution no. 4:

For zsh users. Add alias adb='/Users/<yourUserName>/Library/Android/sdk/platform-tools/adb' to .zshrc file.

Than run source ~/.zshrc command

Solution no. 5:

I don’t know how did you install the android SDK. But in Mac OS, what really worked for me is to reinstall it using brew. All problems solved in a row.

For me, I ran into this issue after switching over from bash to zsh so I could get my console to look all awesome fantastic-ish with Hyper and the snazzy theme. I was trying to run my react-native application using react-native run-android and running into the op’s issue. Adding the following into my ~.zshrc file solved the issue for me:

Solution no. 7:
