使用 package_data 将内置框架复制到 Python 包中

Question

我正在尝试改进 PyBluez installs on macOS. Here 代码在我更改之前的今天的样子。

简而言之，在 macOS 上安装了一个名为 lightblue 的额外包，这取决于一个名为 LightAquaBlue.framework 的框架。今天，它调用 xcodebuild 来构建框架并将其安装到 /Library/Frameworks，但我想将其更改为将框架嵌入到 Python 包中。

这是我所做的：

packages.append('lightblue')
package_dir['lightblue'] = 'osx'
install_requires += ['pyobjc-core>=3.1', 'pyobjc-framework-Cocoa>=3.1']

# Add the LightAquaBlue framework to the package data as an 'eager resource'
# so that we can extract the whole framework at runtime
package_data['lightblue'] = [ 'LightAquaBlue.framework' ]
eager_resources.append('LightAquaBlue.framework')

# FIXME: This is inelegant, how can we cover the cases?
if 'install' in sys.argv or 'bdist' in sys.argv or 'bdist_egg' in sys.argv:
    # Build the framework into osx/
    import subprocess
    subprocess.check_call([
        'xcodebuild', 'install',
        '-project', 'osx/LightAquaBlue/LightAquaBlue.xcodeproj',
        '-scheme', 'LightAquaBlue',
        'DSTROOT=' + os.path.join(os.getcwd(), 'osx'),
        'INSTALL_PATH=/',
        'DEPLOYMENT_LOCATION=YES',
    ])

这会在 osx/（这是 lightblue 包的目录）中构建 LightAquaBlue.framework，然后将其作为 package_data 传递给 setuptools。但是，当我运行pip install --upgrade -v ./pybluez/时，LightAquaBlue.framework是不是复制的：

creating build/lib/lightblue
copying osx/_bluetoothsockets.py -> build/lib/lightblue
copying osx/_LightAquaBlue.py -> build/lib/lightblue
copying osx/_obexcommon.py -> build/lib/lightblue
copying osx/_IOBluetoothUI.py -> build/lib/lightblue
copying osx/__init__.py -> build/lib/lightblue
copying osx/_IOBluetooth.py -> build/lib/lightblue
copying osx/_obex.py -> build/lib/lightblue
copying osx/_lightblue.py -> build/lib/lightblue
copying osx/obex.py -> build/lib/lightblue
copying osx/_macutil.py -> build/lib/lightblue
copying osx/_lightbluecommon.py -> build/lib/lightblue

如果我 setup.py 在 osx/ 中创建一个虚拟文件并将其添加到 package_data，它会被复制。这对我来说表明路径没有混淆。

如果我添加 os.system('ls osx/')，它还会显示 LightAquaBlue.framework 与我的虚拟文件位于同一位置。

    LightAquaBlue
--> LightAquaBlue.framework
    DUMMY_FILE_THAT_WORKS
    _IOBluetooth.py
    _IOBluetoothUI.py
    _LightAquaBlue.py
    __init__.py
    _bluetoothsockets.py
    _lightblue.py
    _lightbluecommon.py
    _macutil.py
    _obex.py
    _obexcommon.py
   obex.py

为什么没有正确复制框架？

它看起来像 setuptools 的文档 contradicts the implementation 实际上 您不能指定要包含在 package_data.

中的目录

不是很优雅，但是我用了：

# We can't seem to list a directory as package_data, so we will
# recursively add all all files we find
package_data['lightblue'] = []
for path, _, files in os.walk('osx/LightAquaBlue.framework'):
    for f in files:
        include = os.path.join(path, f)[4:]  # trim off osx/
        package_data['lightblue'].append(include)
