php - fatal error : Interface 'Psr\Log\LoggerInterface' not found

Question

fatal error :第 20 行 C:\wamp\www\learningpower\vendor\neoxygen\neoclient\src\Logger\LoggerManager.php 中找不到接口(interface)“Psr\Log\LoggerInterface”

我正在尝试执行新氧的基本示例。我尝试了以下代码。

我已经更新了项目的 composer.json。
将此代码添加到 composer.json

"require": {
    "neoxygen/neoclient": "~2.1"
},

在 php 下运行时出现错误。
Fatal error: Interface 'Psr\Log\LoggerInterface' not found in C:\wamp\www\learningpower\vendor\neoxygen\neoclient\src\Logger\LoggerManager.php on line 20
php脚本

auhor: Christophe Willemsen


<?php

  require_once(__DIR__.'/vendor/autoload.php');

use Neoxygen\NeoClient\ClientBuilder;
$client = ClientBuilder::create()
->addConnection('default','http','localhost',7474,true,'neo4j','tarun')
->setAutoFormatResponse(true)
->build();
$query = 'CREATE (user:User {name:"john"})';
$client->sendCypherQuery($query);
$query = 'MATCH (user:User {name:"john"}) RETURN user';
$result = $client->sendCypherQuery()->getResult();
// accessing the user identifier (so the user node) from the result
$john = $result->get('user');
// The $john is a wrapped Node object and have some methods

// The node id
echo $john->getId();
// The labels
print_r($john->getLabels());
// The properties
echo $john->getProperty('name');
$query = 'MATCH (user:User {name:"john"})
CREATE (friend:User {name:"Judith"})
MERGE (user)-[r:FRIEND]->(friend)
RETURN user, friend, r';
$result = $client->sendCypherQuery($q)->getResult();

$john = $result->get('user');
$judith = $result->get('judith');

// What john has for relationships

print_r($john->getRelationships()); // returns relationships objects

// Get a node connected to john

print_r($john->getConnectedNode());
?>

安装 psr/log 包后出现此错误
