內存錯誤PIP安裝Matplotlib

我使用Python 2.7，如果我嘗試安裝，如果我用「畫中畫安裝matplotlib」內存錯誤PIP安裝Matplotlib

什麼可能的問題是Matplotlib我得到這個錯誤？我使用樹莓派2與16GB SD卡。我仍然有8GB數據免費，但仍然得到這個錯誤。請幫忙

看起來你沒有足夠的RAM從頭開始構建matplotlib。爲了克服這種情況，無論是打開的交換：

# 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，如果您安裝在SD卡上有raspbian，您可以從系統信息庫安裝matplotlib：

apt-get install python-matplotlib

嗨，我嘗試交換，但我仍得到相同的錯誤。 – 2015-04-06 08:28:43

如果我給「sudo apt-get安裝matplotlib」它說「E：無法找到軟件包matplotlib」應該做什麼？我是linux新手，所以請幫助 – 2015-04-06 08:29:54

我不記得軟件包的確切名稱（並且在家裏有我的RPi），但是您可以通過發佈'sudo apt-cache search matplotlib'找到它。這應該給你確切的名字。 – 2015-04-07 06:10:15

這個錯誤就要到了，因爲，看起來，pip的緩存機制試圖在緩存之前將整個文件讀入內存......這在有限的內存環境中造成問題，因爲matplotlib大約爲50mb。

一個簡單的辦法，直到PIP進行了修補，使用恆定的空間緩存算法，是運行pip與--no-cache-dir避免緩存：

$ pip --no-cache-dir install matplotlib

甜！這很好！ – Sherlock70 2016-03-24 08:03:46

在Raspberry Pi上有這個問題。解決了！ – fdelia 2016-07-28 15:31:28

在Raspberry Pi 2A上也有這個問題，並解決了它！ – 8one6 2017-01-16 20:50:27
