Question

When installing maven, it reported -bash: mvn: command not found. I checked multiple environment variables and it was correct. Now I don’t know how to solve the problem

Answer 1

/$M2_HOME/bin错了，应该是$M2_HOME/bin

Answer 2

1. source .bash_profile

2. Reopen a window

Answer 3

This is my configuration as follows, you can change the path to yours

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home
export PATH=$PATH:$JAVA_HOME/bin

export M2_HOME=/Users/user/workspace/Tools/apache-maven-3.3.9
export PATH=$PATH:$M2_HOME/bin

After configuration is completed, check which file you configured it in (if it is /etc/profile), and then execute

source /etc/profile

Answer 4

First

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then

brew install maven

Just restart the terminal and it’s done
