我有一个 python-3 使用 的项目plot-directive 即时生成和嵌入 matplotlib 的图表,我正在使用 ReadTheDocs用于自动生成项目的文档。
确实是情节指令 works ok in python-2 ,但它目前在 python-3 中失败。
具体来说,我在 RTD 日志中遇到的故障是:

罪魁祸首可以追溯到 matplotlib 由于 mnissing 'freetype' C lib 而没有被编译:

BUILDING MATPLOTLIB
matplotlib: yes [1.4.2]
python: yes [3.4.0 (default, Apr 11 2014, 13:05:11) [GCC
4.8.2]]
platform: yes [linux]
REQUIRED DEPENDENCIES AND EXTENSIONS
numpy: yes [not found. pip may install it below.]
six: yes [six was not found.]
dateutil: yes [dateutil was not found. It is required for date
axis support. pip/easy_install may attempt to
install it after matplotlib.]
pytz: yes [pytz was not found. pip will attempt to install
it after matplotlib.]
tornado: yes [tornado was not found. It is required for the
WebAgg backend. pip/easy_install may attempt to
install it after matplotlib.]
pyparsing: yes [pyparsing was not found. It is required for
mathtext support. pip/easy_install may attempt to
install it after matplotlib.]
pycxx: yes [Official versions of PyCXX are not compatible
with matplotlib on Python 3.x, since they lack
support for the buffer object. Using local copy]
libagg: yes [pkg-config information for 'libagg' could not
be found. Using local copy.]
freetype: no [The C/C++ header for freetype2 (ft2build.h)
could not be found. You may need to install the
development package.]
OPTIONAL LATEX DEPENDENCIES
dvipng: yes [version 1.14]
ghostscript: yes [version 9.10]
latex: yes [version 3.1415926]
pdftops: no
============================================================================
* The following required packages can not be built:
* freetype
为了使文档生成通过,我被迫通过模拟它来“禁用”绘图指令,如 instructed in the RTD FAQ , 在
./conf.py
中使用以下代码文件。我尝试了
virtualenv
的各种组合(有或没有站点包可见性),特定于 rtd requirements.txt
,没有成功。有没有人找到办法做到这一点?
这些是对那些愿意深入研究这个问题的人的一些提示:
pip-requirements.txt
用于设置构建服务器的文件,如从 RTD 的来源中找到的。 最佳答案
从今天开始,问题正式解决,据rtfd issue #896 .
还为 python-3 安装了所有必需的依赖项(matplotlib、scipy 和 numpy),因此不再需要模拟。
要使用它,请在 Advanced settings
中做出以下选择:
Install Project: Install your project inside a virtualenv using setup.py install
Python interpreter: CPython 3.x
Use system packages: Give the virtual environment access to the global site-packages dir
. ...虽然经过一些培训,编写与 python-2/3 兼容的代码很容易。
