numpy - numpy安装错误。 (Mingw32CCompiler实例没有属性 'compile_options')

Question

我在Windows8 / Anaconda spyder(2.7)中使用python
我正在尝试更新Theano的最新信息。当我通过安装theano时

"pip install --upgrade theano"

该错误发生在numpy安装部分。

尽管numpy可在anaconda GUI中使用，但在anaconda终端中未显示。 (pip show numpy不输出任何内容)

错误如下所示(当我尝试安装numpy时，会发生相同的错误)

  File "c:\users\user\appdata\local\temp\pip_build_user\numpy\numpy\distutils\command\build_src.py", line 329, in build_extension_sources

    sources = self.generate_sources(sources, ext)

  File "c:\users\user\appdata\local\temp\pip_build_user\numpy\numpy\distutils\command\build_src.py", line 386, in generate_sources

    source = func(extension, build_dir)

  File "numpy\core\setup.py", line 455, in generate_config_h

    rep = check_long_double_representation(config_cmd)

  File "numpy\core\setup_common.py", line 191, in check_long_double_representation

    cmd.compiler.compile_options.remove("/GL")

AttributeError: Mingw32CCompiler instance has no attribute 'compile_options'

Answer 1

这很可能是一个小问题。不幸的是，即使在我建议修复后，我也无法升级theano，但是遵循this one这样的逐步指南可能会起作用。

发生此特定问题是因为numpy.distutils.misc_util.mingw32()不应该返回False。另请参见this discussion和the source 。我决定手动将系统变量MSYSTEM设置为MINGW32，该变量在我的系统中未定义，但我发现它不太可能破坏任何其他行为。

就像我说的那样，这不能保证升级会起作用，也不能保证没有副作用，但是它将解决这里提到的问题。
