问题描述:
1.当你卸载python库的时候,如:pip uninstall pandas
2.当你想要更新python库的时候,如:pip install --upgrade pandas
等等… 就会出现PermissionError: [WinError 5] 问题
废话不多说,分三步完全解决该问题:
第一步:
关闭跟python相关的所有程序,如jupyter,pycharm,Anaconda等等,这一步非常重要!!!
好了,第一步完成下面开始常规操作的两步:
第二步:
赋予用户对python的“完全控制”的权限,步骤如下:
找到按照python的位置,本文用的是Anaconda,安装在D盘,位置为:D:\Anaconda3。找到python->右键->属性->安全->点击“组或用户名”中的Users->编辑->点击点击“组或用户名”中的Users->把“完全控制”打钩->应用->OK
第三步:
执行完第二步一般就能解决问题。如果还没解决问题的话,请执行第三部,找到你安装python的文件夹,本人用的是Anaconda3,那么就直接对该文件夹(本人安装位置为D:\Anaconda3),右键属性,按照第二步的方法执行一遍就OK了!
当然,如果你用的pycharm或其他软件安装的python,那么就找到你安装位置的那个文件夹,同理右键->属性,执行第二步的方法, 搞定!
**总结:**一定要关闭所有跟python相关的程序!
补充知识:jupyter notebook_启动出错_ValueError: Please install nodejs 5+ and npm before continuing installation.
错误描述:
在启动jupyter notebook的时候虽然能进入Home,但是后台还是报错,如下:

解决方案:
因为我的电脑上安装了Anaconda,所以我打开Anacoda后
等待系统安装,完成后在cmd命令行中再次输入jupyter notebook,问题解决
