Matplotlib编译错误: TypeError:不可排序的类型: str() < int()
Matplotlib编译错误: TypeError:不可排序的类型: str() < int()
提问于 2014-11-20 02:55:49
我正在尝试使用python setup.py build在Python3.4上添加matplotlib-1.4.2。根据文档，它在python3.4上受支持。我收到以下错误消息：
IMPORTANT WARNING:
pkg-config is not installed.
matplotlib may not be able to find some of its dependencies
============================================================================
Edit setup.cfg to change the build options
BUILDING MATPLOTLIB
matplotlib: yes [1.4.2]
python: yes [3.4.0 (default, Nov 17 2014, 15:12:48) [GCC
4.1.2 20080704 (Red Hat 4.1.2-48)]]
platform: yes [linux]
REQUIRED DEPENDENCIES AND EXTENSIONS
numpy: yes [version 1.9.1]
six: yes [using six version 1.8.0]
dateutil: yes [using dateutil version 2.2]
pytz: yes [using pytz version 2014.9]
tornado: yes [using tornado version 4.0.2]
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.]

我遇到了类似的错误，并能够通过安装一个可选的依赖项来修复它。具体来说，在我的情况下，在distutil中有一个'bug‘，松散的版本号比较可能会在Python3中触发错误，因为在distutils/version.py:343中对字符串和整数类型进行隐式比较，这是从Matplotlib的setup.py调用的。如果您需要更多详细信息，请参阅Issue 14894。
因为没有安装可选的依赖项，所以版本号检查返回一个字符串("Failed to identify version“)。当然，这不能与数字版本相比，后者抛出了与您看到的相同的异常。
sudo apt-get install libfreetype6-dev
pip install matplotlib安装了libfreetype (一个可选的依赖项)后，distutil的LooseVersion看到了一个版本号，并且比较输入正确。此后Matplotlib安装得很好。
