我正在关注此链接http://www.pymolwiki.org/index.php/User:Tlinnet/Linux_Install安装 pymol。我需要 libfreetype6-dev 作为依赖项，但无法安装。
fmp@eva03:~/Bins$ sudo apt-get install libfreetype6-dev

以下是尝试安装 pymol 的最后一行

答案1
选项一
如果您不需要 1.8 版本，并且您正在使用 Ubuntu 14.04 或更新版本，则可以通过官方 Ubuntu 存储库安装 1.7 版本。只需运行以下命令即可安装pymol版本和pymol依赖项：
sudo apt-get update
sudo apt-get install pymol
如果仍然抱怨libfreetype6-dev，请运行以下命令来修复它，然后再次运行上述命令。
sudo apt-get clean
sudo apt-get update
sudo apt-get purge libfreetype6-dev
要通过 apt-get 搜索可用的软件包，请运行以下命令，如本例所示：
apt-cache search pymol
要将结果缩小到包含特定单词的结果，请使用grep如下示例：
apt-cache search pymol | grep pymol
列出可用版本：
apt-cache show pymol | grep "Version:"
列出更多信息：
apt-cache show pymol
方案二
或者，如果您坚持安装下载的版本，请运行以下命令进行安装libfreetype6-dev：
sudo apt-get clean
sudo apt-get update
sudo mv /usr/share/man/man1/freetype-config.1.gz ~/
sudo apt-get install libfreetype6-dev
这会将manpage文件移动到您的主目录，因此您必须从那里查看该文件，而不是使用manpage。
