尝试使用cpan安装但总是收到该错误我需要帮助我应该怎么做，我没有perl的背景，我只需要运行回归并且该模块是必需的。

这是我第一次安装perl模块，因为它在我的回归文件中是必需的。

Answer 1

所以这不是一件容易的事。 但你可以通过一些修改来构建它。 我还建议安装一个brewer perl而不是使用perl系统

$ brew install perl

# Update the CPAN to latest
$ perl -MCPAN -e 'install Bundle::CPAN'

# Install Installer paackage
$ perl -MCPAN -e 'install Module::Install'

现在从下面的url下载源代码

https://cpan.metacpan.org/authors/id/S/SZ/SZBALINT/WWW-Curl-4.17.tar.gz

提取并进行两处更改

Curl.c

#include "curlopt-constants.c"

至

#undef CURL_DID_MEMORY_FUNC_TYPEDEFS
#define CURL_DID_MEMORY_FUNC_TYPEDEFS 0
#include "curlopt-constants.c"

然后在Makefile.PL更改

if($e =~ /(OBSOLETE|^CURL_EXTERN|_LAST\z|_LASTENTRY\z)/) {

至

if($e =~ /(OBSOLETE|^CURL_EXTERN|^CURL_STRICTER\z|_LAST\z|_LASTENTRY\z)/) {

然后在下载的文件夹中运行make命令

Answer 2

以下对我有用（perl 5，版本28，颠覆0（v5.28.0）为darwin-thread-multi-2level，XCode 9.4.1构建）：

wget https://www.cpan.org/modules/by-module/WWW/WWW-Curl-4.17.tar.gz
tar zxvf WWW-Curl-4.17.tar.gz
cd WWW-Curl-4.17
