Question

当我尝试使用pip升级matplotlib时，它会输出：

为什么会失败？非常感谢！

Answer 1

这是已修复（https://github.com/matplotlib/matplotlib/pull/3414）master上的已知错误。

该错误在于处理搜索freetype安装。如果您安装Linux软件包freetype-dev，您将避免此错误并能够编译matplotlib。

sudo apt-get install libfreetype6-dev

Answer 2

在Ubuntu 14服务器上，您还需要安装libxft-dev

sudo apt-get install libfreetype6-dev libxft-dev

Answer 3

我在尝试使用matplotlib在Python 3上安装pip3时遇到了同样的问题，似乎这个问题与Python 3的简单安装有关，并且做了：

sudo apt-get build-dep matplotlib

接着是

sudo pip3 install matplotlib

可能是比仅选择性地安装与matplotlib相关的库的更好的解决方案。

Answer 4

由于mac没有apt-get you，在OSX上你可能需要这样做：

brew install freetype

然后你可以运行：

pip install matplotlib

Answer 5

在寻找Fedora 24的答案时找到此页面。

RPM解决方案是：

dnf install freetype-devel

Answer 6

如果你重新运行Ubuntu服务器14.04，你应该添加这个字体依赖

sudo apt-get install libxft-dev

Source

Answer 7

我尝试使用sudo pip直接更新，但最后没有保存更改。所以我首先在终端中使用update cmd：

git tag -d `git tag | grep -E '^*\._test$'`

然后我使用了sudo install：

sudo apt-get update

最后通过这种方法安装它。

Answer 8

对于那些使用Fedora 25的人来说，我需要这两个软件包才能使它工作：

sudo dnf install freetype-devel gcc-c++

Answer 9

这对我有用：

python -m pip install -U pip setuptools
python -m pip install matplotlib
