Python - PIP 安装疑难解答 - PermissionError: [WinError 5] Access is denied [英] Python - PIP install trouble shooting - PermissionError: [WinError 5] Access is denied

问题描述

在使用 PIP 安装新软件包甚至将 pip 本身升级到最新版本时，我收到以下错误.我正在使用 Python 3.4 的 Windows 8.1 机器上运行 pip.

I get the following error when using PIP to either install new packages or even upgrade pip itself to the latest version. I am running pip on a windows 8.1 machine with Python 3.4.

该消息告诉我我没有文件的管理权限(我的帐户是管理员帐户).

The message is telling me I don't have Administrative Permission on the files (my account is an Administrator Account).

对于如何解决此问题的任何想法，我将不胜感激，因为它妨碍了安装软件包和使用 Python 的进展.

I would appreciate any thoughts on how to resolve this, as it is getting in the way of installing packages and progressing with Python.

推荐答案

E:由于这个答案似乎获得了一些人气，我要补充一点:在大多数情况下，在全球范围内做事并不是一个好主意.几乎总是正确的答案是:使用不全局安装东西的项目环境，例如使用 virtualenv.

E: Since this answer seems to have gained some popularity, I will add: doing things globally is most of the time not a great idea. Almost always the correct answer is: use a project environment where you're not installing things globally, e.g. with virtualenv.

对于那些可能遇到相同问题的人:

For those that may run into the same issue:

以管理员身份运行命令提示符.在帐户中拥有管理员权限并不总是足够的.在 Windows 中，可以通过右键单击可执行文件并选择以管理员身份运行"来以管理员身份运行.所以，在开始菜单中输入cmd"，右键单击cmd.exe，以管理员身份运行.

Run the command prompt as administrator. Having administrator permissions in the account is not always enough. In Windows, things can be run as administrator by right-clicking the executable and selecting "Run as Administrator". So, type "cmd" to the Start menu, right click cmd.exe, and run it as administrator.
