Numpy安装错误.(Mingw32CCompiler实例没有属性'compile_options')

Question

我使用python与windows8/anaconda spyder(2.7)我试图更新Theano最新.当我安装theano时

"pip install --upgrade theano"

错误发生在numpy安装部分.

虽然numpy可以在anaconda GUI中使用,但是在anaconda终端中没有显示.(pip show numpy什么都没输出)

错误如下(当我尝试安装numpy时,会发生同样的错误)

  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

这很可能是一个麻木的问题。不幸的是，即使在我建议的修复之后我也无法升级 theano，但遵循像这样的分步指南可能会起作用。

出现此特定问题是因为numpy.distutils.misc_util.mingw32()返回 False，而它不应该返回 False。另请参阅此讨论和来源 。我决定手动设置系统变量，MSYSTEM该MINGW32变量在我的系统中未定义，而且我发现它不太可能破坏任何其他行为。

正如我所说，这并不能保证升级一定有效，也不保证不会有副作用，但它会解决这里提到的问题。
