dot安装和使用

1.安装

apt-get install graphviz

如果报错说缺少依赖文件，则使用apt自动安装依赖项

apt-get -f install

我在安装中报错：

dpkg: unrecoverable fatal error, aborting:
 fork failed: Cannot allocate memory

重新执行安装命令时，出现新错误

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem. 

按照提示执行

dpkg --configure -a

又报错

Errors were encountered while processing:
 graphviz:i386

网上搜索后，尝试如下解决

aptitude update

报错：

The program 'aptitude' is currently not installed. You can install it by typing:
apt install aptitude

根据提示，执行

apt install aptitude

报错

You might want to run 'apt-get -f install' to correct these:

根据提示执行

apt-get -f install

完成，重新安装 graphviz

apt-get install graphviz

成功

可见，错误原因是aptitude没安装。
