Upgrading issues from Nette v2.1 to v3.1

pesparza3

Hello,
I am working on website that has the Nette framework v2.1, and I need to upgrade it to v3.1. I ran the composer update command and it did it properly (no errors displayed). The composer.lock files shows the new version. Even though the composer.json file seems to be updated (as the modified date for the file was updated), it still shows the previous version (v2.1). I updated this file manually to reflect the new v3.1 settings. But when I try to load the site, I just got a blank page. Part of the issue is that I did not update it gradually (as recommended), but when I run the composer update command, it goes all the way up to v3.1. How can I troubleshoot this?

Then I tried to start another brand new website using composer create-project nette/web-project PROJECT_NAME, but it tried to install the latest version (v3.3). This can’t be done since v3.3 requires php >= 8.1, and the server I am using has php v7.2. So my other question is how can I create a new nette project using v3.1 instead of v3.3 using the composer command?

Your help is greatly appreciated.

add this “config” section to your composer.json, it will update your packages depending on platform>php version instead of your installed php version

"config": {
    "platform": {
      "php": "7.2"
    }
  },

Thank you for your response. It didn't do the trick. But I noticed that I have the php version in another place: require. I removed it from there, but nothing.

Try “composer outdated” command, it should show package versions that you can update for your platform php version.

And there is migration guide for every version https://doc.nette.org/…tions/to-2-2
“Always update gradually, so not from Nette 2.4 to 3.1, but first to 3.0 and then to 3.1.”

This is what I get when I run composer outdated: nette/nette 3.2.1 3.2.2 Nette Framework
How do I run an update for this specific dependency?

Also, I wanted to migrate gradually, but when running the composer update command, it went all the way to v3.1 by default. how can I upgrade to v2.2 using the composer command? Is there a way to force the composer to install a specific version?

Many thanks!

Replace composer.json version numbers of Nette packages to ~2.2.0 and run composer update, it will update packages to latest 2.2.x versions.

Do yourself a favor and read the Composer documentation.
You will not understand everything immediately and will probably need to only understand version ranges and require and update commands at this moment, but knowing about possible solutions and where to find them will get you easily in top 10%.
Understanding the tools helps to solve most of the problems, forum and other support solutions are for finding right direction and solving edge cases.
