当我尝试在我的 Debian 机器上安装 Net::SSH2 模块时，我得到了以下日志。我没有安装 libssh2-dev，但仍然收到此错误。它还说“找不到您的 C 编译器”。我很确定我确实安装了 C 编译器。我该如何修复这个问题？

The libssh2 library is required by this module. If you don't have it, you can
download it from http://www.libssh2.org; you may also need OpenSSL, which can
be obtained from http://www.openssl.org , or libgcrypt, which can be obtained
from http://www.gnupg.org .
Debian: sudo aptitude install libssh2-1-dev
OpenSUSE: sudo zypper in libssh2-1 libssh2-devel
You can pass your libssh2 lib and include dirs (and extra link args) on the
command line. E.g.:
perl Makefile.PL lib=$HOME/libssh2/lib inc=$HOME/libssh2/include \
ldargs="-lz"
These can also be set through the LIBSSH2_LIB/LIBSSH2_INCLUDE/LIBSSH2_LDARGS
environment variables.
To build with libgcrypt instead of OpenSSL, pass 'gcrypt' as a parameter to
Makefile.PL, e.g.:
perl Makefile.PL gcrypt
If you want to build on Windows, see the file BUILDING.WIN32 in the
distribution.

答案1
正如你所说，你使用的是 Debian，最简单的方法是
aptitude install libnet-ssh2-perl
但是如果您确实希望从 CPAN 安装它，请确保您已经安装了所有开发工具和库以及 SSH 库：
aptitude install build-essential libssh2-1-dev
您可以从 CPAN 安装模块 - 只需通过上述步骤在最小的 Debian 安装上进行验证。
