[英]ubuntu 14.04, pip cannot upgrade matplotllib
當我嘗試使用pip升級matplotlib時,輸出:

為什么失敗了? 非常感謝!
這是一個已知的錯誤,已在master上修復( https://github.com/matplotlib/matplotlib/pull/3414 )。
該錯誤在於搜索自由類型安裝的處理。 如果安裝Linux軟件包freetype-dev,則可以避免該錯誤並能夠編譯matplotlib
。
sudo apt-get install libfreetype6-dev
在Ubuntu 14服務器上,您還需要安裝libxft-dev
sudo apt-get install libfreetype6-dev libxft-dev
嘗試使用pip3
在Python 3上安裝matplotlib
,我遇到了同樣的問題,看來這個問題與Python 3的准系統安裝有關,並且執行以下操作:
sudo apt-get build-dep matplotlib
其次是
sudo pip3 install matplotlib
與僅選擇性地安裝與matplotlib
相關的庫相比,它是一個更好的解決方案。
由於mac沒有apt-get,因此在OSX上,您可能需要執行以下操作:
brew install freetype
然后您可以運行:
pip install matplotlib
在尋找fedora 24的答案時找到了此頁面。
RPM解決方案是:
dnf install freetype-devel
我也嘗試直接使用sudo pip更新,但更改未保存在最后。 所以我首先在終端中使用update cmd:
sudo apt-get update
然后我用sudo install:
sudo apt-get install libffi-dev
最后通過執行此方法安裝它。
對於使用Fedora 25的用戶,我需要以下兩個軟件包才能使其正常工作:
sudo dnf install freetype-devel gcc-c++
這為我工作:
python -m pip install -U pip setuptools
python -m pip install matplotlib
