    ImportError: libBLT.2.4.so.8.5: cannot open shared object file: No such file or directory, please install the python-tk package

Answer 1

查看Debian的错误报告：https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=751767（据我所知，matplotlib并不依赖于“blt”这个东西）

Answer 2

作为一个临时解决办法，你可以在

mv libBLT.2.4.so.8.6 libBLT.2.4.so.8.5

这个路径下放东西，应该就能正常工作了。

Answer 3

没有这样的文件或目录，请安装 python-tk 这个软件包

你可以通过下面的命令来安装这个软件包：

sudo apt-get install python-tk
