python 在windowns下以管理员运行代码（pip安装权限不够）

 

 

win10下，pip安装的时候权限不够，无法安装；

1.以管理员权限权限运行cmd;

2.使用 --user 参数；不过只能当前安装的人使用；安装路径也在%APPDATA%；

 --user                      Install to the Python user install directory for your platform. Typically ~/.local/, or
                              %APPDATA%\Python on Windows. (See the Python documentation for site.USER_BASE for full
                              details.)

3.用python以管理员权限运行代码；

import os
import subprocess
import time
import ctypes, sys

#             \'wcwidth\', \'zipp\']
pip_list = [ \'requests\']


def send_cmd(cmd, encoding=\'utf-8\'):
    \'\'\'
    cmd发送命令
    :param cmd:命令
    :param encoding: 编码方式，默认utf-8,出现乱码用gbk
    :return:
    \'\'\'
    print("==" * 40)
    print("【CMD】 ----> {}".format(cmd))
    print("installing...")
    res = subprocess.run(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    print("【RES】 ----> {}".format(res.stdout.decode("utf-8").strip()))
    return res.stdout


def pip_install():
    print("PIP package install begin...")
    python = "python"
    cmd = "where python"
    res = send_cmd(cmd=cmd).decode("utf-8").strip()
    res_list = [i.strip() for i in res.split("\r\n")]
    print("==" * 40)
    print(str(res_list))
    flag = 0
    for index, value in enumerate(res_list):
        if "Python36" in value:
            python = value
            print("==" * 40)
            print("python36 路径：" + value)
            os.chdir(os.path.dirname(os.path.abspath(python)))
            print("当前路径为：%s" % str(os.getcwd()))
            flag = 1
            break
    if flag == 0:
        os.chdir(r"C:\Program Files\Python36")
        print("当前路径为：%s" % str(os.getcwd()))
    # cmd = "python.exe -m pip install --user --upgrade pip"
    cmd = "python.exe -m pip install --upgrade pip"
    res = send_cmd(cmd=cmd)
    for i in pip_list:
        cmd = "python.exe -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host https://pypi.tuna.tsinghua.edu.cn " + str(
            i)
        res = send_cmd(cmd=cmd)
        time.sleep(0.5)
    print("==" * 40)
    print("pip install success!")



def is_admin():
    try:
        return ctypes.windll.shell32.IsUserAnAdmin()
    except:
        return False


if __name__ == "__main__":
    if is_admin():
        print("==" * 40)
        pip_install()
        print("==" * 40)
    else:
        if sys.version_info[0] == 3:
            ctypes.windll.shell32.ShellExecuteW(None, "runas", sys.executable, __file__, None, 1)
