ft2build.h 位于此处:
C:\ Program Files \ GnuWin32 \ include
最初,我犯了同样的错误:
Fatal Error C1083: Cannot Open Include file: 'tiffio.h': No such file or directory VC++ 2008
但从那时起,我已经纠正了这个特定错误(我已将上面的目录添加到“include”列表,而不是“可执行文件”列表),但我仍然收到错误。完整的输出是:

在Ubuntu 10.10上构建matplotlib时也会出现此错误。解决方案是:
sudo apt-get install python-dev libfreetype6-dev
答案 1 :(得分:14)
您是否正确安装了freetype?如果有,则在安装目录下的某处应该有一个名为ft2build.h
的文件,找到该文件的目录是您应该使用-I
指定的文件。字符串“GnuWin32”不会出现在构建命令的输出中的任何位置,因此看起来您没有将该目录放在正确的包含列表中。

Mac OS X的另一个解决方案是使用Homebrew安装Freetype。
brew install freetype
答案 3 :(得分:3)
对于那些可能在Mac OS 10.6(雪豹)和Python 2.7上遇到同样问题的人。 ,我找到的最简单的解决方案是获取一个make文件,下载Numpy,scipy和matplotlib并为你编译它们。您可以自定义make文件以仅为matplotlib。以下是解决方案的link。

我在red hat中遇到了同样的错误6.原来我需要安装freetype-devel
,而不是freetype
(使用sudo yum install freetype-devel
)
答案 5 :(得分:2)
我还通过在Mac OS X上使用自制软件安装freetype来解决这个问题。但是,这还不够,因为在Mac OS X 10.7下库没有正确链接。所以我必须手动将它们添加到pip
命令,如下所示:
brew install freetype
brew install libpng
LDFLAGS="-L/usr/local/opt/freetype/lib -L/usr/local/opt/libpng/lib" CPPFLAGS="-I/usr/local/opt/freetype/include -I/usr/local/opt/libpng/include -I/usr/local/opt/freetype/include/freetype2" pip install matplotlib
请注意,您还必须添加文件夹/usr/local/opt/freetype/include/freetype2
,默认情况下不包含在自制程序通知中,但会导致找不到ft2build.h
。

我能够通过执行以下操作在Windows上解决此问题:
set INCLUDE=%INCLUDE%;C:\tmp\msvcr90-x32
set LIB=%LIB%;C:\tmp\msvcr90-x32
pip.exe install matplotlib
Windows上的Freetype链接库可以在这里找到:http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib(来自meawoppl的评论)
只需下载“matplotlib-1.x-windows-link-libraries.zip”,然后从zip中打开README。
答案 7 :(得分:2)
我花了数小时试图让matplotlib与最新的python 3,pip,setuptools一起安装...一切最终对我有用的是 https://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib下载wheel文件并在同一目录中执行该文件:
pip install matplotlib‑3.2.0rc2‑cp38‑cp38‑win_amd64.whl
答案 8 :(得分:0)
将文件下载到C盘上的文件夹中。
在Windows CMD提示符管理员导航您使用路径
cd..
或cd wheels
(在我的情况下,我将文件保存到c:\Wheels
)
然后输入pip install YourFilename.whl
结果
Processing c:\wheels\scipy-0.19.0-cp27-cp27m-win_amd64.whl
Requirement already satisfied: numpy>=1.8.2 in c:\python27\lib\site-packages (from scipy==0.19.0)
Installing collected packages: scipy
Successfully installed scipy-0.19.0

jetson nano(aarch64-linux-gnu)遇到了同样的问题。这对我有用-
sudo apt-get install python-dev libfreetype6-dev
pip3 install --upgrade cyton
pip3 install matplotlib
答案 10 :(得分:0)
这个错误在Google中引起很高的重视,因此像其他几个错误一样,我将忽略它仅询问Windows的事实。
在Debian 10(Buster)上,我必须做:
sudo apt install libfreetype6-dev pkg-config
请注意pkg-config
依赖性;没有它,就会安装FreeType标头,但是matplotlib无法找到它们。它会在吐出输出页面之前对此发出警告,因此很容易错过:
IMPORTANT WARNING:
pkg-config is not installed.
matplotlib may not be able to find some of its dependencies
