Magento upgrade CLI problem

Question

I want to upgrade to Magento 2.1.9. Entered command:

composer require magento/product-commu**m**ity-edition 2.1.9 --no-update

After command "composer update" I've got error message:

Problem 1 - The requested package magento/product-commumity-edition could not be found in any version, there may be a typo in the package name.

Found the typo and changed the command to "..community-edition.." But still get the same error message (showing "commumity"). There is no typo anymore. Checked it several times.

What is wrong?

Thanks!

Answer 1

Found the error. In composer.json there was following code:

"require": {

    "magento/product-community-edition": "2.1.9",
    "composer/composer": "@alpha",
    "magento/product-commumity-edition": "2.1.9"
},

I cancelled the last line and finally it worked.
