我安装了libgd-devel。这与（CPAN GD module install failure using Cygwin）不同。 CPAN测试员说GD安装好了

http://www.cpantesters.org/distro/G/GD.html

Windows 8.1 64位，Cygwin 2.6.1 32位，Perl v5.22.2

我从libwebp安装了libwebp-devel和setup-x86，现在它说成功但测试失败了。

2.53有效！这也可能有用：stackoverflow.com/questions/260593/…您必须在CPAN中使用install L/LD/LDS/GD-2.53.tar.gz，因为它在命令行上不起作用。 –Chloe

如何为Perl安装GD？
