安装python模块时报错如何解决
前言:
这几天把python版本升级后,发现pip安装模块好多都报错(暂不确定是不是因为升级导致的),我定睛一看,发现是权限的问题,那么怎么解决呢?
1 权限问题
C:\Users\ljf>pip install xlwt
Exception:
Traceback (most recent call last):

os.makedirs(path)

mkdir(name, mode)PermissionError: [WinError 5] 拒绝访问。: 'c:\\program files\\python35\\Lib\\sit
e-packages\\xlwt'
注意看我标红的那部分,提示说权限错误,拒绝访问,我们这样解决:
1 首先切换到c:\\program files\\目录下,
2 我们鼠标右击python35这个目录,点击 属性 ,
3 首先切换到 安全 这个大标题下面,选中当前登陆的用户,然后再点击编辑,编辑完以后不要忘记点击应用,
4 点击添加的权限,我这里为了方便全部一块选了,反正根据自己的实际情况而定,最后点击应用,再点击确定就大功告成。
5 我们此时再看看自己pip,是不是能够安装模块了。
或者下载模块包手动安装
pip3 install setup.py
求MySQL模块包手动下载地址
pip3 install setup.py报错
ERROR: Could not find a version that satisfies the requirement setup.py (from versions: none)
ERROR: No matching distribution found for setup.py
可能是我下载的3.8版本,找不到合适的设置
如果你没安装 在IDE里import mysql
