MAMP failed to start: Apache could’t be started. Please check your MAMP installation and configuration

Solution 1:

In / applications / MAMP / library / bin, find the file envvars and rename it to_ envvars。

It doesn’t work for me.

Solution 2:

sudo /Applications/MAMP/bin/startApache.sh

or

sudo /Applications/MAMP/Library/bin/apachectl start

There is no display.

Solution 3:

Change document root to a fixed address that you don’t know how to delete.
MAMP > Preferences > Server > Document Root

Still failed.

Solution 4:

sudo /Applications/MAMP/Library/bin/apachectl restart

report errors:

shell-init: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted
job-working-directory: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted
httpd not running, trying to start

I solved it lazily

Final solution

I had a video conference with the professor. He asked me to come to him

    delete the installation package, turn off the computer, wait for five minutes, and then turn on the system. If there is an update, update it, and then download the MAMP software again

    Well I guess it’s the system update that works, updating Catalina to Big Sur
    as a person who doesn’t shut down several times a year, and who can delay several versions of the update
    After doing all the above honestly In front of the professor, there was no problem at all, and then he was connected
    for a time, I was a little embarrassed, and I told him by email how many attempts I had made I’m impressed
