Question

如何告诉MacPorts我已经安装了某个库？

例如，我从头开始构建libcurl以获得带有nghttp2，openssl和zlib的http2协议。我将它们安装到/opt/local - 与我系统上的所有MacPort库相同的位置。但是，Macports不承认它们已经安装。

如何告诉MacPorts这些已安装以及它们的版本？为什么？因为我正在尝试：

port install py35-pip但会列出未安装libz和openssl。

MacPorts不支持此功能，原因有多种：

您不应手动修改/opt/local中通常由MacPorts管理的文件。 MacPorts保留有关已安装文件的某些元数据（如所需的依赖关系），当您在/opt/local中手动安装文件时，这些文件不再有效。
MacPorts不知道您用于构建在/opt/local中手动安装的二进制文件的配置。它可能是一个不再适用于某种依赖的版本，它可以在C ++代码的情况下针对不同的C ++标准库构建，或者由于许多其他原因而可能不兼容。由于MacPorts希望减少那些修改了某些端口的人的请求的支持负担，因此MacPorts的支持功能不是这样做的。

但是，MacPorts已经支持使用nghttp2支持安装curl。请参阅port variants curl的输出：

curl has the variants:
   ares: Support resolving names asynchronously
   darwinssl: Allow secure connections using GNU TLS
     * conflicts with gnutls ssl wolfssl
   gnutls: Allow secure connections using GNU TLS
     * conflicts with darwinssl ssl wolfssl
   gss: Support the Generic Security Service API
   http2: Support HTTP/2 with nghttp2
   idn: Enable support for internationalized domain names (IDN)
   metalink: Support Metalink XML download description files
   openldap: Support performing Lightweight Directory Access Protocol queries with OpenLDAP
   sftp_scp: Support SFTP/SCP connections via libssh2
   spnego: Enable SPNEGO authentication support
[+]ssl: Allow secure connections using OpenSSL
     * conflicts with darwinssl gnutls wolfssl
   universal: Build for multiple architectures
   wolfssl: Allow secure connections using wolfSSL, formerly CyaSSL
     * conflicts with darwinssl gnutls ssl

因此，在这种情况下，您可以使用curl +http2安装sudo port install curl +http2（如果您尚未安装）或使用sudo port upgrade --enforce-variants curl +http2（如果已安装/usr/local ）实现同样的目标。
