内存错误PIP安装Matplotlib

我使用Python 2.7，如果我尝试安装，如果我用“画中画安装matplotlib”内存错误PIP安装Matplotlib

什么可能的问题是Matplotlib我得到这个错误？我使用树莓派2与16GB SD卡。我仍然有8GB数据免费，但仍然得到这个错误。请帮忙

看起来你没有足够的RAM从头开始构建matplotlib。为了克服这种情况，无论是打开的交换：

# create swap file of 512 MB 
dd if=/dev/zero of=/swapfile bs=1024 count=524288 
# modify permissions 
chown root:root /swapfile 
chmod 0600 /swapfile 
# setup swap area 
mkswap /swapfile 
# turn swap on 
swapon /swapfile

或者，如果您安装在SD卡上有raspbian，您可以从系统信息库安装matplotlib：

apt-get install python-matplotlib

嗨，我尝试交换，但我仍得到相同的错误。 – 2015-04-06 08:28:43

如果我给“sudo apt-get安装matplotlib”它说“E：无法找到软件包matplotlib”应该做什么？我是linux新手，所以请帮助 – 2015-04-06 08:29:54

我不记得软件包的确切名称（并且在家里有我的RPi），但是您可以通过发布'sudo apt-cache search matplotlib'找到它。这应该给你确切的名字。 – 2015-04-07 06:10:15

这个错误就要到了，因为，看起来，pip的缓存机制试图在缓存之前将整个文件读入内存......这在有限的内存环境中造成问题，因为matplotlib大约为50mb。

一个简单的办法，直到PIP进行了修补，使用恒定的空间缓存算法，是运行pip与--no-cache-dir避免缓存：

$ pip --no-cache-dir install matplotlib
