使用from_dist()函数在python中创建一个pip._internal.req.req_uninstall.UninstallPathSet对象，该对象表示给定源的卸载路径集

from pip._internal.req.req_uninstall import UninstallPathSet

# 创建UninstallPathSet对象

uninstall_paths = UninstallPathSet(from_dist('package_name'))

# 获取卸载路径集的所有路径

paths = uninstall_paths.paths

print(paths)

# 添加新的卸载路径

new_path = '/path/to/package_name'

uninstall_paths.add_path(new_path)

paths = uninstall_paths.paths

print(paths)

# 移除卸载路径

uninstall_paths.remove_path(new_path)

paths = uninstall_paths.paths

print(paths)

# 检查路径是否在卸载路径集中

is_present = uninstall_paths.is_present(new_path)

print(is_present)
