Class 'Pimple\Container' not found

Question

I am trying to install Pimple in my project following https://github.com/silexphp/Pimple readme file.

Error message I receive is:

Fatal error: Class 'Pimple\Container' not found in E:\www\public\index.php on line 9

My composer.json file is:

{
  ...
  "require-dev": {
    "phpunit/phpunit": "5.1.*"
  },
  "require": {
    "pimple/pimple": "~3.0"
  }
}

When I do:

composer update

or

composer install

the message is: Nothing to install or update

In vendor/bin I can see only phpunit files. I can see however pimple in composer.lock

My PHP index.php file:

<?php

    use Pimple\Container;

    $co = new Container();

?>

Could you please help me make it work?

Answer 1

vendor / autoload.php不包括在内，这会导致错误。

Answer 2

尝试删除供应商内容，然后通过作曲家再次安装dev。
