Package fabpot/php-cs-fixer is abandoned, you should avoid using it. Use friendsofphp/php-cs-fixer instead.

What is your current folder when you are executing this command?

andy_lin · October 31, 2016, 7:22pm

/usr/share/nginx/html
this is my magento root folder

dmitry_fedyuk · October 31, 2016, 9:11pm

Does the Magento root folder contain the vendor/mage2pro/allpay subfolder?

andy_lin · October 31, 2016, 9:14pm

yes

dmitry_fedyuk · October 31, 2016, 9:18pm

Did you create it manually?

andy_lin · October 31, 2016, 9:20pm

No
I don’t have.

So, it looks like the mage2pro/allpay composer package is alredy installed in your system by somebody.
That is why Composer writes «Nothing to install or update».
The question is who did install it and by which means he did it.
Does the Magento root composer.json file contain the mage2pro/allpay package declaration?

yes i did composer.json file contain the mage2pro/allpay package declaration

Maybe you ran the composer require --prefer-source mage2pro/allpay:* command twice?
If you have already successfully implemented the steps 1-7 of the installation instruction, then I recommend to consider the step 8 (the package installation) as implemented too, and do the steps 9, 10, and 11.
