作曲安装错误：ZipArchive :: extractTo（）：完全抽出路径超过MAXPATHLEN（260）

Question

当我运行：

php composer.phar require kartik-v/yii2-widgets "*" 

我得到下面的输出（使用-vvv详细标志）：

我甚至尝试过使用“--prefer-source”标志，但是我得到了同样的错误。有没有办法告诉作曲家增加MAXPATHLEN？究竟在抱怨哪条路？

Answer 1

我认为这是抱怨，这C:/Users/Michael/AppData/Local/Composer/files/kartik-v/bootstrap-fileinput/f95a7e5fa0a9db1ead445e438653aa71e9f599f9.zip可能是超过256个字符。从我所知道的情况来看，你不可能有比Windows更长的路径。

不确定是否有解决方案。您可能可以创建一个短路径并将应用程序安装在那里。

Answer 2

尝试使用--prefer源标志

composer install --prefer-source 

Answer 3

作曲家抱怨过长的PHP在Windows上下载的路径。 Windows的最大路径长度（MAXPATHLEN）为260个字符，所以我认为你不能改变它。

当我安装Symfony时遇到了这个问题，我通过使用项目目录的短路径（例如C：\ projects \ myproject）来修复它。

在调查这个问题，我发现它也可以通过安装的时候，像这样使用--prefer源标志固定：

php composer.phar install --prefer-source 

请注意，你需要的git在你的Windows shell路径此工作，因为这从Github检查源而不是下载分发文件。它也比较慢。

还要注意的是，你可能有再次安装使用--prefer-source标志之前删除vendor/文件夹：

rm -rf vendor/ 

Answer 4

尽量缩短像c://www/yii-project项目的完整路径，因为Windows操作系统不允许目录超过250个字符

Answer 5

尝试在命令行运行

mklink /j <Link> <Target> 

创建符号bolic链接并将您的文件路径长度减少到少于260个字符。更多详细信息https://technet.microsoft.com/en-us/library/cc753194(v=ws.11).aspx
