由于重写MAXPATHLENGTH而安装phpunit/phpunit时出现的编写器错误

Question

我有一个PHP项目，其文件夹结构如下所示：

C:\Users\Bas\Documents\Web_development\Projects\Back_end\Current\Project_name\Workspace

我已经为这个项目安装了composer，并且已经安装了一些软件包。我的composer.json看起来是这样的：

{
  "name": "Bas/Project_name",
  "description": "...",
  "minimum-stability": "stable",
  "license": "MIT",
  "authors": [
    {
      "name": "Bas",
      "email": "..."
    }
  ],
  "require": {
    "psr/log": "1.0.2",
    "monolog/monolog": "1.22.0",
    "ip2location/ip2location-php": "8.0.2"
  }
}

当我试图安装phpunit/phpunit版本5.7.x (最新)包时，它会给出[ErrorException] ZipArchive::extractTo(): Full extraction path exceed MAXPATHLEN (260)错误。完整的错误消息如下所示：

我正在用composer require phpunit/phpunit命令安装这个包。

我已经对这个问题做了一些研究，它是由一个到长的目录结构引起的，但是当计算我当前的目录结构时，它只有87个字符。

我尝试使用composer install参数运行composer update命令和--prefer-source命令。这两种方法都不起作用，也给了我同样的错误。

我目前正在运行Windows 10 64位。

这个问题是如何发生的？因为我在MAXPATHLEN (260)变量下有一个目录结构。

有没有办法在不改变我的目录结构的情况下解决这个问题？

你的路很长。它是否太长取决于项目中目录结构的深度。

记住，使用Composer将创建子文件夹。至少您将创建vendor/phpunit/phpunit (22个字符)，并且在此基础上创建PHPUnit本身的所有子文件夹。我发现这条路径就是一个例子：src/Framework/Constraint/JsonMatches/ErrorMessageProvider.php (另62个字符)。

再加上一些目录分隔符，我们至少有87 + 22 +2+ 62 =173个字符长。比你想象的更接近260的最大值。

解压缩模拟对象组件时会出现问题。我发现了一条有趣的路：tests/MockObject/Generator/namespaced_class_implementing_interface_dont_call_parent_constructor.phpt -101个字符。再加上供应商文件夹vendor/phpunit/phpunit-mock-objects (36个字符)和另外两个目录分隔符，我们的位置是87 + 36 +2+ 101 = 226 chars --接近最大值。现在您只需要来自任何地方的另外34个字符，可能在解压缩过程中创建了一个临时文件名，并且达到了极限。

缩短你现有的路径，它就能工作了。
