无法在scikits.talkbox上安装MacOS

Question

我正试图在我的MacOS上安装MacOS。我使用Python 3.7.3

如果我跑了

pip install scikits.talkbox

或

pip3 install scikits.talkbox

我得到以下错误(我希望我包括了一切)

我的怀疑是，setuptools有一些问题，我刚刚升级了，没有结果。有什么想法吗？

macOS上的Python3.7.4也有相同的错误。它与包的Cython相关代码相关：

scikits/talkbox/tools/src/cffilter.c:3287:21: error: no member named 'exc_type' in 'struct _ts'
    *type = tstate->exc_type;
            ~~~~~~  ^
scikits/talkbox/tools/src/cffilter.c:3288:22: error: no member named 'exc_value' in 'struct _ts'; did you mean 'curexc_value'?
    *value = tstate->exc_value;
                     ^~~~~~~~~
                     curexc_value

首先，scikits.talkbox包已经非常老了，它的最后一次发布是在2009年8月28日(参见0.25)，那是在大约10年前！它似乎与Python 3不兼容，甚至还没有移植。

不过，它确实在Python2.7上成功安装：

$ python -V
Python 2.7.16
$ python -m pip install numpy scipy
...
$ python -m pip install scikits.talkbox
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

如果您想要Python3支持，您将不得不在scikits.talkbox Github页面上提出一个问题，但从回购的历史来看，作者似乎不再积极参与该项目。

出于好奇，我尝试找到在Python3上安装的解决方案。基本上，这个包包括预编译的Cython文件，这些文件与Python3不兼容(给出了*.c文件的错误)。我尝试用Python3.7上的Cython重新编译它：

# download the source code from PyPi
$ wget https://files.pythonhosted.org/packages/65/a0/410eb932e1765186a4728d1c9b28410695d554c47439bcb69a407d5d3921/scikits.talkbox-0.2.5.tar.gz
$ tar -xvzf scikits.talkbox-0.2.5.tar.gz
$ cd scikits.talkbox-0.2.5/

# re-compile with Cython on Python 3.7
$ python3 -V
Python 3.7.4
$ python3 -m pip install numpy scipy cython
$ find . -name '*.pyx' -exec cython {} \;
$ python3 -m pip install .
...
Successfully installed scikits.talkbox-0.2.5

我似乎成功地安装了，但是当您使用它时，：

$ python3
Python 3.7.4 (default, Sep  7 2019, 18:29:04) 
[Clang 10.0.0 (clang-1000.11.45.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import scikits.talkbox
['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    __all__ += tools.__all__
AttributeError: module 'tools' has no attribute '__all__'
>>> 

..which也是包的回购中报告的未解决的、未被注意到的错误：

https://github.com/cournape/talkbox/issues/8

所以..。看来你唯一的选择是：

• 使用Python2.7
• 使用不同的、更兼容Python3 3的库
  • 例如。利布罗萨在scikits.talkbox和Python3有什么问题吗？中的建议
