致命错误：在第20行的C：\ wamp \ www \ learningpower \ vendor \ neoxygen \ neoclient \ src \ Logger \ LoggerManager.php中找不到接口'Psr \ Log \ LoggerInterface'
我正在尝试执行neoxygen的基本示例。我尝试过以下代码。
我更新了项目的composer.json。 将此代码添加到composer.json
"require": {
"neoxygen/neoclient": "~2.1"
},
我在php下运行时收到错误。
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

<?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包之后我收到此错误

任何解决方案。将非常感谢帮助。
答案 0 :(得分：1)
运行laravel项目的CLI Web服务器时遇到相同的问题。我通过完全删除（删除）供应商文件夹并运行来解决该问题。
作曲家安装
下载完所有文件后，现在一切正常。
答案 1 :(得分：0)
我认为现有的composer.lock具有一些不匹配的依赖项。重命名composer.lock和供应商文件夹，然后尝试“ composer安装”或“ composer更新”。希望会有所帮助。
答案 2 :(得分：0)
我遇到了类似的问题，主要原因是没有使用 autoload.php，试试这个：
require_once 'vendor/autoload.php';
它没有__DIR__。
