我试图在Ubuntu 14.04的python2 virtualenv中安装matplotlib，并遇到以下错误：

../virtualenv/bin/pip install matplotlib

MemoryError

有关可能发生的事情以及为什么会出现内存错误的任何想法？

Answer 1

尝试在低内存环境中安装大型软件包（matplotlib）时，这似乎是MemoryError。看来原因是缓存机制，因为禁用缓存可以解决问题。

试试这个：

pip install --no-cache-dir matplotlib

尝试在ubuntu上安装matplotlib时出现编码错误
