Question

column exist but when migration it returns

SQLSTATE[42000]: Syntax error or access violation: 1072 Key column doesn't exist in table

when i remove foreign key the problem is solved

  public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });
}

   public function up()
{
    Schema::create('skills', function (Blueprint $table) {
        $table->increments('id');
        $table->string('skill_name')->nullable();
        $table->decimal('skill_note')->nullable();           
        $table->timestamps();
    });
}


   public function up()
    {
        Schema::create('skill_user', function (Blueprint $table) {
            $table->increments('id');
            $table->unsignedInteger('user_id');
            $table->foreign('user_id ')
                ->references('id')->on('users');
            $table->unsignedInteger('skill_id');
            $table->foreign('skill_id')
                ->references('id')->on('skills');
            $table->decimal('note')->nullable();
            $table->timestamps();
        });
    }

Answer 1

In version 6 (the one you're using for what I could read in the comments), the increments('id') method doesn't create a Unsigned Integer, it rather creates a Unsigned Big Integer, therefore you need to change your foreign keys to

$table->unsignedBigInteger('user_id');
$table->unsignedBigInteger('skill_id');

Answer 2

Try this once.

 $table->integer('user_id')->unsigned(); $table->integer('skill_id')->unsigned();

If it does not work, I would suggest to run composer install and migrate:fresh
