这里有很多正确答案。但是，缺少了一个项目，如果没有它，我无法从命令行运行模拟器。

export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=$PATH:$JAVA_HOME/bin

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator       # can't run emulator without it
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

所以这是上面的答案加上这个问题的解决方案的汇编。

如果使用zsh(而不是bash)，要编辑的文件是~/.zshrc。

1)开放式基地概况:

open  ~/.bash_profile

2)在基本剖面中添加以下线条:

export PATH=${PATH}:/Users/<username>/Library/Android/sdk/build-tools/27.0.3

保存并关闭基本配置文件。

对我来说27.0.3工作得很好。

ANDROID_HOME环境与ANDROID_SDK_ROOT环境相同，这意味着它定义了SDK安装目录的路径。

点击这里了解更多。

我设置了独立于Android studio的Android SDK，这让我能够更好地控制内容的位置。

首先，我从官方网站下载了Android SDK(命令行工具)。

cd $HOME/Downloads
curl https://dl.google.com/android/repository/commandlinetools-mac-7302050_latest.zip --output android-sdk.zip

其次，我解压缩下载目录中的文件，这个过程将生成一个名为cmdline-tools的目录。

unzip android-sdk.zip

第三，在本地目录中创建一个名为android的目录。 (/usr/local系统范围，由本地管理员(通常是您)安装的只读文件)

sudo mkdir /usr/local/android

第四，我将解压生成的目录移动到android目录，将其重命名为sdk。(将来我会在sdk旁边添加ndk目录)

sudo mv cmdline-tools /usr/local/android/sdk

第五，我手动将环境变量添加到我个人目录中的.zshrc文件中。

nano $HOME/.zshrc

# ...

# Set environment variables for Android SDK
export ANDROID_SDK_ROOT=/usr/local/android/sdk
export ANDROID_HOME=$ANDROID_SDK_ROOT

# Insert executable file paths in PATH environment variable
export PATH=$PATH:$ANDROID_HOME/bin
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

要设置ANDROID_HOME变量，你需要知道你是如何安装android开发安装的。

如果您不知道，可以检查您的计算机中是否存在以下路径。根据您使用的内容，将以下文件添加到.bashrc、.zshrc或.profile中

如果你安装了自制软件，

export ANDROID_HOME=/usr/local/opt/android-sdk

检查该路径是否存在:

如果你在网站上安装了android studio，

export ANDROID_HOME=~/Library/Android/sdk

最后将其添加到path:

export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

如果你懒得打开编辑器，可以这样做:

echo "export ANDROID_HOME=~/Library/Android/sdk" >> ~/.bashrc
echo "export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools" >> ~/.bashrc

把爱传递给下一个懒惰或时间紧张的人。

我想偷懒，在这里找一个Bash脚本;没有。所以我决定是时候学习了，现在就在这里。

#! /bin/bash

# This script will download the Android command line toools to a path of your choosing.
#
# Syntax  : <cmd> <zip> <path>
#
# Example : run with ./get-cli.sh commandlinetools-mac-8512546_latest.zip /usr/local/android
#
# For the latest .zip matching your system visi:
#
#   https://developer.android.com/studio#command-tools 
#
# Note: supplying no args will default to the example
# 
# Respectfully,
#   -Tricknology
#

# command-line-tools zip
cmd_line_tools=$1

# directory to add it to 
android_home_dir=$2

# use defaults if none specified
if [[ cmd_line_tools=="" ]]; then
    #default to aarch64
    cmd_line_tools='commandlinetools-mac-8512546_latest.zip'
fi

if [[ android_home_dir=="" ]]; then
    #statements
    android_home_dir='/usr/local/android'

在Mac OS X上设置ANDROID_HOME, JAVA_HOME环境变量

在.bash_profile文件中添加

export JAVA_HOME=$(/usr/libexec/java_home)

export ANDROID_HOME=/Users/$USER/Library/Android/sdk

export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

为测试

echo $ANDROID_HOME
echo $JAVA_HOME
