将python3包添加到Buildroot

Question

Buildroot是一种可用于为嵌入式系统板构建Linux映像的工具。

Buildroot附带了一组预定义的Python包，可以从菜单中选择。

此外，Buildroot还添加了一个漂亮的Python脚本，可以导入任何属于PyPI存储库的包，称为“scanpypi”。

然而，似乎该脚本仅适用于Python2。尝试导入较新的包时，会出现错误，例如：

./support/scripts/scanpypi websockets -o package
buildroot package name for websockets: python-websockets
Package: python-websockets
Fetching package websockets
Downloading package websockets from https://pypi.python.org/packages/b6/12/6194aac840c65253e45a38912e318f9ac548f9ba86d75bdb8fe66841b335/websockets-4.0.1.tar.gz...
Traceback (most recent call last):
  File "./support/scripts/scanpypi", line 653, in <module>
    main()
  File "./support/scripts/scanpypi", line 604, in main
    package.load_setup()
  File "./support/scripts/scanpypi", line 250, in load_setup
    setup = imp.load_module('setup', s_file, s_path, s_desc)
  File "/tmp/scanpypi-qbY6eQ/python-websockets/websockets-4.0.1/setup.py", line 11, in <module>
TypeError: 'encoding' is an invalid keyword argument for this function

这个无效的关键字失败了。

也：

./support/scripts/scanpypi websocket-server -o package
buildroot package name for websocket-server: python-websocket-server
Package: python-websocket-server
Fetching package websocket-server
Downloading package websocket-server from https://pypi.python.org/packages/74/64/e86581ee7775a2e08aca530b41e1a1e3ee6b320233b1eff301dcb86d1636/websocket_server-0.4.tar.gz...
Traceback (most recent call last):
  File "./support/scripts/scanpypi", line 653, in <module>
    main()
  File "./support/scripts/scanpypi", line 604, in main
    package.load_setup()
  File "./support/scripts/scanpypi", line 247, in load_setup
    os.chdir(self.tmp_extract)
OSError: [Errno 2] No such file or directory: '/tmp/scanpypi-YXROmL/python-websocket-server/websocket-server-0.4'

对于包含下划线（_）而不是破折号（ - ）的包名称，这个失败了。

Answer 1

我为scanpypi创建了一个Python3移植。

编辑

根据@yegorich的要求，我很高兴地告知现在scanpypi可用于Python 2/3！

我的链接版本仍然可以用于直接从GitHub安装更新的版本。
