Hello,

You can try. I never listen this error before so many people have installed it.

You can delete all the files and then start over again. If still same that means server might require restart or manually install the packages.

I am not sure about your server but you should have option for command line even cPanel has it too.

Thank you

Hello,

You should delete and install them all packages by

1. removing the vendor folder
2. removing the composer.lock file
3. install packages

```
rm -rf vendor
rm composer.lock
composer install
```

Please check with your server admin/host too, it might be pear or something else. They can help you check.

Thank you
