篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了python 在windowns下以管理员运行代码（pip安装权限不够）相关的知识，希望对你有一定的参考价值。
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("
")]
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 FilesPython36")
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)
