项目描述
安装
从PyPI安装
$ pipenv install pythonfinder从Github安装
$ pipenv install -e git+https://github.com/sarugaku/pythonfinder.git#egg=pythonfinder用法
使用PythonFinder很简单。只需导入它并请求一个Python
>>> from pythonfinder import Finder
>>> f = Finder()
>>> f.find_python_version(3, minor=6)
PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/python'), _children={}, is_root=False, only_python=False, py_version=PythonVersion(major=3, minor=6, patch=5, is_prerelease=False, is_postrelease=False, is_devrelease=False, version=<Version('3.6.5')>, architecture='64bit', comes_from=PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/python'), _children={}, is_root=True, only_python=False, py_version=None, pythons=None), executable=None), pythons=None)
>>> f.find_python_version(2)
PathEntry(path=PosixPath('/home/hawk/.pyenv/shims/python2'), ...py_version=PythonVersion(major=2, minor=7, patch=15, is_prerelease=False, is_postrelease=False, is_devrelease=False, version=<Version('2.7.15')>, architecture='64bit', comes_from=PathEntry(path=PosixPath('/home/hawk/.pyenv/shims/python2'), _children={}, is_root=True, only_python=False, py_version=None, pythons=None), executable=None), pythons=None)
>>> f.find_python_version("anaconda3-5.3.0")查找命名的发行版，例如 anaconda3-5.3.0
PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/anaconda3-5.3.0/bin/python3.7m'), _children={'/home/hawk/.pyenv/versions/anaconda3-5.3.0/bin/python3.7m': ...}, only_python=False, name='anaconda3-5.3.0', _py_version=PythonVersion(major=3, minor=7, patch=0, is_prerelease=False, is_postrelease=False, is_devrelease=False,...))PythonFinder甚至可以找到测试版发行版
>>> f.find_python_version(3, minor=7)
PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.7.0b1/bin/python'), _children={}, is_root=False, only_python=False, py_version=PythonVersion(major=3, minor=7, patch=0, is_prerelease=True, is_postrelease=False, is_devrelease=False, version=<Version('3.7.0b1')>, architecture='64bit', comes_from=PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.7.0b1/bin/python'), _children={}, is_root=True, only_python=False, py_version=None, pythons=None), executable=None), pythons=None)
>>> f.which('python')
PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/python'), _children={}, is_root=False, only_python=False, py_version=PythonVersion(major=3, minor=6, patch=5, is_prerelease=False, is_postrelease=False, is_devrelease=False, version=<Version('3.6.5')>, architecture='64bit', comes_from=PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/python'), _children={}, is_root=True, only_python=False, py_version=None, pythons=None), executable=None), pythons=None)Windows支持
PythonFinder通过PATH环境变量和默认随Python 3一起提供的符合PEP-514的查找器，原生支持Windows。在Windows上的使用变为
>>> from pythonfinder import Finder
>>> f = Finder()
>>> f.find_python_version(3, minor=6)
PythonVersion(major=3, minor=6, patch=4, is_prerelease=False, is_postrelease=False, is_devrelease=False, version=<Version('3.6.4')>, architecture='64bit', comes_from=PathEntry(path=WindowsPath('C:/Program Files/Python36/python.exe'), _children={}, is_root=False, only_python=True, py_version=None, pythons=None), executable=WindowsPath('C:/Program Files/Python36/python.exe'))
>>> f.find_python_version(3, minor=7, pre=True)
PythonVersion(major=3, minor=7, patch=0, is_prerelease=True, is_postrelease=False, is_devrelease=False, version=<Version('3.7.0b5')>, architecture='64bit', comes_from=PathEntry(path=WindowsPath('C:/Program Files/Python37/python.exe'), _children={}, is_root=False, only_python=True, py_version=None, pythons=None), executable=WindowsPath('C:/Program Files/Python37/python.exe'))
>>> f.which('python')
PathEntry(path=WindowsPath('C:/Python27/python.exe'), _children={}, is_root=False, only_python=False, py_version=None, pythons=None)查找可执行文件
PythonFinder还提供了跨平台上的which功能，并使用懒惰加载和快速返回来在此任务上保持高效。
>>> f.which('cmd')
PathEntry(path=WindowsPath('C:/windows/system32/cmd.exe'), _children={}, is_root=False, only_python=False, py_version=None, pythons=None)
>>> f.which('code')
PathEntry(path=WindowsPath('C:/Program Files/Microsoft VS Code/bin/code'), _children={}, is_root=False, only_python=False, py_version=None, pythons=None)
>>> f.which('vim')
PathEntry(path=PosixPath('/usr/bin/vim'), _children={}, is_root=False, only_python=False, py_version=None, pythons=None)
>>> f.which('inv')
PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/inv'), _children={}, is_root=False, only_python=False, py_version=None, pythons=None)架构支持
PythonFinder 支持在所有平台上进行架构特定查找
>>> f.find_python_version(3, minor=6, arch="64")
PathEntry(path=PosixPath('/usr/bin/python3'), _children={'/usr/bin/python3': ...}, only_python=False, name='python3', _py_version=PythonVersion(major=3, minor=6, patch=7, is_prerelease=False, is_postrelease=False, is_devrelease=False, is_debug=False, version=<Version('3.6.7')>, architecture='64bit', comes_from=..., executable='/usr/bin/python3', name='python3'), _pythons=defaultdict(None, {}), is_root=False)集成
