Fixed by WordPress update - cause unknown.

我有几个插件使用各种自定义WP-CLI 我写的命令。

然后，我将WordPress项目从一个工作正常的WordPress项目复制到同一服务器上的另一个WordPress项目，该项目的输出顺序变得混乱。

（在我的开发VM和生产服务器上都会发生同样的情况。）

该函数混合了WP-CLI API 和功能来自php-cli-tools 这取决于它。

这是我的命令之一（调用了两个额外的函数来显示各种提示…）

function add_user() {
    WP_CLI::line( \'Add a user by hand. * indicates required fields. \' );

    $questions = [
        \'id\'         => \'Unique ID (entirely optional, same as the S001,S002... column in CSV file)\',
        \'first_name\' => \'First name *\',
        \'last_name\'  => \'Last name *\',
        \'user_email\' => \'Email address *\',
        \'user_pass\'  => "Password (or leave blank and we\'ll create one",
        \'company\'    => \'Company\',
        \'position\'   => \'Position (i.e. job)\',
    ];

    $data = $this->add_user_questions( $questions );

    WP_CLI::line( \' \' );

    foreach ( $questions as $k => $v ) {
        WP_CLI::line( $v . \': \' . $data[ $k ] );
    }

    $confirmed = cli\\choose( \'Are you happy with your answers?\', \'yn\', \'n\' );

    if ( \'y\' !== strtolower( $confirmed ) ) {
        WP_CLI::error( \'Cancelled.\' );
    }

    $data[\'line\'] = 1;  // used to indicate line number when reading a file. we only have 1 user, so we set it to 1.

    // Ask them to choose a group
    $groups = [
        \'1\' => \'sponsors\',
        \'2\' => \'exhibitors\',
        \'3\' => \'owners_sponsors\',
        \'4\' => \'owners_exhibitors\'
    ];

    foreach ( $groups as $k => $v ) {
        WP_CLI::line( $k . \'. \' . $v );
    }

    $group = \\cli\\choose( \'Which group?\', implode( \'\', range( 1, 4 ) ), null ); // it\'ll keep asking if invalid

    $data[\'group\'] = $groups[ $group ]; // map back to array

    $send_email = \\cli\\choose( \'Send them an automated email?\', \'yn\', null );

    if ( strtoupper( $send_email ) == \'Y\' ) {
        $send_email = true;
    } else {
        $send_email = false;
    }

    $new_user = Nominations_Public::import_user( $data, $send_email );

    if ( get_class( $new_user ) ) {
        WP_CLI::success( \'The new WordPress user_id is \' . $new_user->ID );
    } else {
        WP_CLI::error( \'Unknown error.\' );
    }
}

private function add_user_questions( $questions ) {

    $req_fields = [ \'first_name\', \'last_name\', \'user_email\' ];

    $data = [ ];

    foreach ( $questions as $k => $v ) {
        $data[ $k ] = $this->add_user_prompt_for_question( $v, in_array( $k, $req_fields ) );
        switch ( $k ) {
            case \'id\':
                $data[ $k ] = strtoupper( $data[ $k ] );
                if ( ! Nominations_Public::verify_unique_csv_id( $data[ $k ] ) ) {
                    WP_CLI::error( \'Sorry, that unique ID is already taken. (You can leave it blank.)\' );
                }
                break;
            case \'user_email\':
                if ( email_exists( $data[\'user_email\'] ) ) {
                    WP_CLI::error( \'Sorry, email address already exists. Remember you may be able to use a + sign.\' );
                }
                break;
            case \'user_pass\':
                if ( empty( $data[ $k ] ) ) {
                    $data[ $k ] = wp_generate_password();
                }
                break;
        }
    }

    return $data;
}

private function add_user_prompt_for_question( $question, $required = false ) {
    $default = ( true === $required ) ? false : \'\';   // if default not provided, \\cli\\prompt\\ will force an answer
    return trim( \\cli\\prompt( $question . \'? \', $default ) );
}

以下是运行CLI时的CLI输入/输出：

Unique ID (entirely optional, same as the S001,S002... column in CSV file)? :    
First name *? : Foo
Last name *? : Bar
Email address *? : [email protected]
Password (or leave blank and we\'ll create one? : 
Company? : 
Position (i.e. job)? : 
Are you happy with your answers?? [y/N]y
Which group?? [1/2/3/4]1
Send them an automated email?? [y/n]n
Success: The new WordPress user_id is 9
Add a user by hand. * indicates required fields. 

Unique ID (entirely optional, same as the S001,S002... column in CSV file): 
First name *: Foo
Last name *: Bar
Email address *: [email protected]
Password (or leave blank and we\'ll create one: WJ8bMnAb6bxD
Company: 
Position (i.e. job): 
1. sponsors
2. exhibitors
3. owners_sponsors
4. owners_exhibitors
 (line 1) - added as WP_User 9

您会注意到WP_CLI:：line输出被延迟；这个\\cli\\prompt 和\\cli\\choose 调用（加上WP\\u CLI：：success消息）似乎是首先发生的（例如，组列表是在最后打印的，这时应该在“Which group？”提示之前。）

If I change instances of WP_CLI::line to `\\cli\\line\', this seems to fix them.

但这不应该是正确的语法，也不能解释为什么它在同一服务器上的另一个WordPress副本中工作。

多个插件使用WP\\u CLI，因此我使用require_once 将其包括在内，如下所示：

    if ( defined( \'WP_CLI\' ) && WP_CLI ) {
        // Command line support for development
        require_once plugin_dir_path( dirname( __FILE__ ) ) . \'/wp-cli.php\';
    }

另外，在PHPStorm中：尽管我已经定义了/Users/wt/vm/wordpress/www/wp-cli/php （这是我的WP-CLI副本所在的位置）位于包含路径中，位于调用有问题的安装上\\cli\\choose 以红色突出显示为“未定义命名空间”错误。

有什么建议吗？
