Question

I upgraded a number of module but when I come to compile (bin/magento setup:di:compile) I get the error below. Anyone know how to fix it? Thank you Andy

Still struggling with this.

I found some advice to find which class is causing issues by adding echo "Class: ".$path."\n to the /setup/src/Magento/Setup/Module/Di/Code/Reader/ClassesScanner.php file.

Now I'm getting the below when running setup:di:compile

Line 432 of the /var/www/vhosts/mysite.co.uk/public_html/vendor/composer/ClassLoader.php(432): Is (self::$includeFile)($file);

Tu Van I did try removing the vendor folder but this didn't work either. Hope someone can advise. Andy

• Tu Van: Hey Andy, try to remove vendor directory and run composer install.
• Zahid Hussain Magento: disable your custom or third party modules one by one and try compile
• AndyJH: Thanks guys - Tu what is the exact command for composer? Thanks

Answer 1

There is a syntax error either correct it by hand or as suggested delete the whole vendor folder and reinstall it. Be careful when editing magento core files. Here I list some commands that may be useful to you.

If you can manually fix the error after run the command, composer dump autoload php bin/magento setup:di:compile .

Otherwise use the command rm -rf vendor composer install

• AndyJH: Hi Gennaro Before I run the rm -rf vendor composer install How would I manually fix the syntax error? The error code suggests the error is at Line 432 of the /var/www/vhosts/mysite.co.uk/public_html/vendor/composer/ClassLoader.php(432): Which is (self::$includeFile)($file); but this line does contain the ; Thank you
• AndyJH: I copied the ClassLoader.php from a working dev site to the effected site and can now run the command bin/magento setup:di:compile There were differences in the other ClassLoader.php file. I just hope this won't have any negative effect later on.
• GerranoMargeno: Don't worry, I always suggest you copy the files either from the official version of magento on github or I suggest you download a virgin open source version in zip format so you can always go and check the differences.
