bdist_wheel在MSYS2下不起作用

Question

我正在尝试在Windows 7 VirtualBox VM上的MSYS2 MINGW64 shell下使用Python软件包。 该软件包可在Linux上成功构建，安装和导入。

我可以在MSYS2下构建一个二进制轮子...

$ python setup.py bdist_wheel
running bdist_wheel
running build
running build_py
running build_ext
running build_scripts
installing to build/bdist.mingw/wheel
running install
running install_lib
running install_egg_info
running egg_info
writing stencila.egg-info/PKG-INFO
writing top-level names to stencila.egg-info/top_level.txt
writing dependency_links to stencila.egg-info/dependency_links.txt
reading manifest file 'stencila.egg-info/SOURCES.txt'
writing manifest file 'stencila.egg-info/SOURCES.txt'
Copying stencila.egg-info to /build/bdist.mingw/wheel/./stencila-0.24.0+a67987b-py2.7.egg-info
running install_scripts
creating build/bdist.mingw/wheel/stencila-0.24.0+a67987b.dist-info/WHEEL

但实际上是“空的”（缺少已编译的C ++扩展和Python源代码）...

因此，尽管它将安装，但无法导入...

我在Appveyor上得到了相同的行为。

相比之下，使用python setup.py bdist_egg构建的二进制鸡蛋包含了所有内容...

在MSYS2上，MSYS2路径转换与bdist_wheel之间存在冲突。 一种解决方法是使用--bdist-dir选项指定临时构建目录的绝对路径（不应为“ build”，因为bdist_wheel会删除该目录，这意味着每次都需要重新构建）：

python setup.py bdist_wheel --bdist-dir=$PWD/build-temp
