我尝试使用 Redhat 7.0 上的pip安装 pygit2 python库但是我收到以下错误。如果有人知道如何解决这个问题，请告诉我。我真的会想到任何想法。
这是pip install pygit2之后的控制台输出：

如果你手动安装了libgit2，那么你需要确保你的操作系统在尝试加载它时知道在哪里找到它。在大多数系统中安装到/usr/local/就足够了，但有时您必须运行sudo ldconfig以便库加载程序识别更改。
如果您尚未将其安装在标准位置，则必须导出LD_LIBRARY_PATH或硬编码pygit2模块中的路径。这相当于安装文档中的[{http://www.pygit2.org/install.html#libgit2-within-a-virtual-environment]虚拟环境中的（libgit2）。
