Question

文件结构如下：

index.php
composer.json
composer.lock
-lib
--books
---SearchClient.php (contains class books\SearchClient

以下docker-compose.yml + PHP可在Windows上运行：

{
    "name"             : "keithdavis/books",
    "description"      : "",
    "version"          : "0.1",
    "minimum-stability": "beta",
    "require"          : {
        "ext-curl"         : "*",
        "ext-json"         : "*",
        "guzzlehttp/guzzle": "^6.3"
    },
    "autoload"         : {
        "psr-4": {
            "books\\": "lib"
        }
    }
}

<?php

use books\SearchClient;

require_once __DIR__."/vendor/autoload.php";
$oSearchClient = new SearchClient();

但是，在macOS（Mojave）上：

( ! ) Fatal error: Uncaught Error: Class 'books\SearchClient' not found in /var/www/html/search.php on line 6
( ! ) Error: Class 'books\SearchClient' not found in /var/www/html/search.php on line 6
Call Stack
#   Time    Memory  Function    Location
1   0.0032  416944  {main}( )   .../search.php:0

在调试中，似乎出现了路径“ lib”是问题，但是我尝试了“ / lib”，但这也不起作用。我认为也许我没有正确安装Composer。我是Windows上经验丰富的PHP开发人员，但对Mac来说还相对较新，因此我并不是100％知道在Mac上安装Composer的最佳方法。我在全球范围内遵循以下说明：

查看您的文件结构，您搜索客户端类的名称空间需要为 func exp(_ s : String, _ term: String) -> String{ //term_inator: Any Char not in the Sequence. guard let first = s.first else {return ""} return """ \(s.dropFirst().appending(term).reduce(("\(first)",1)){ r, c in let t = c == r.0.last! let tc = t ? r.1 : 0 let tb = t ? "" : "\(c)" let ta = t ? "" : r.1 > 2 ? "\(r.1)" : r.1 == 2 ? "\(r.0.last!)" : "" return (r.0 + ta + tb, tc + 1) }.0.dropLast()) """} print(exp(initialString, " ")) let initialString = "abbbaaa" // ab3a3 let initialString = "aahhhgggg" // aah3g4 let initialString = "aabbaa" // aabbaa

这是因为要在lib文件夹上设置名称空间书。您可以通过添加

将自动装带器直接指向书本文件夹，而不是在命名空间中使用书本两次

namespace books\books;

请确保在更改自动加载时运行{ "name" : "keithdavis/books", "description" : "", "version" : "0.1", "minimum-stability": "beta", "require" : { "ext-curl" : "*", "ext-json" : "*", "guzzlehttp/guzzle": "^6.3" }, "autoload" : { "psr-4": { "books\\": "lib/books" } } }，以便重建名称空间。

希望这会有所帮助。

为什么composer自动加载功能无法在macOS Docker容器上运行？
