如何在无网络环境下安装Python库Streamlit？

<code class="python">import os, sys

requires_set = []

def dependent_query(pkg_name):
    output = os.popen(f"pip show {pkg_name}")
    requires = output.readlines()
    for line in requires:
        if "requires:" in line:
            requires_list = line.strip().split(':')[1].split(',')
            requires_list = [i for i in requires_list if i]
            if requires_list:
                for requires in requires_list:
                    if requires:
                        requires_set.append(requires.strip())
                        dependent_query(requires.strip())

def download(requires_set):
    if isinstance(requires_set, list) and requires_set:
        for pkg in requires_set:
            print(f"==========开始下载 {pkg}==========")
            pkg_output = os.system(f"pip download {pkg}")
            print(pkg_output)

if __name__ == '__main__':
    pkg_name = sys.argv[1]
    requires_set.append(pkg_name)
    dependent_query(pkg_name)
    print(f"安装顺序参考：{requires_set[::-1]}")
    download(requires_set)</code>

<code class="bash">python download_streamlit.py streamlit</code>

<code class="bash">pip install streamlit-0.71.0-py2.py3-none-any.whl</code>
