pip install access denied on Windows

提问by Bruno Klein

I am trying to run pip install mitmproxyon Windows, but I keep getting access denied, even with cmdand PowerShellusing the Run as Administratoroption.

我正在尝试pip install mitmproxy在 Windows上运行，但我一直拒绝访问，即使使用cmd并PowerShell使用该Run as Administrator选项也是如此。

WindowsError: [Error 5] Access is denied: 'c:\users\bruno\appdata\local\temp\easy_install-0fme6u\cryptography-0.9.1\.eggs\cffi-1.1.2-py2.7-win-amd64.egg\_cffi_backend.pyd'

How can I make this work?

我怎样才能使这项工作？

In case of windows, in cmd try to run pip install using python executable

在 Windows 的情况下，在 cmd 中尝试使用 python 可执行文件运行 pip install

e.g.

例如

python -m pip install mitmproxy

this should work, at least it worked for me for other package installation.

这应该有效，至少它对我的其他软件包安装有效。

9. Save your changes

1. 打开 Python 外壳
2. 进入任务管理器

Personally, I found that by opening cmdas adminthen run python -m pip install mitproxy seems to fix my problem.

就个人而言，我发现cmd以管理员身份打开然后运行 python -m pip install mitproxy 似乎可以解决我的问题。

When all else fails, try quitting your IDE. I had many cases in which PyCharm was causing this. As soon as I quit PyCharm, I was able to finally install my packages from the command line. Alternatively, you can also install through PyCharm itself in Settings -> Project: xxx -> Project Interpreter -> +.

当所有其他方法都失败时，请尝试退出您的 IDE。我有很多 PyCharm 导致这种情况的案例。退出 PyCharm 后，我终于能够从命令行安装我的软件包。或者，您也可以在 Settings -> Project: xxx -> Project Interpreter -> 中通过 PyCharm 本身安装+。

Opening command prompt As Administrator just worked for me without using Python executable. Right click on command prompt shortcut and choose "Run as Administrator". Then run the following command.

以管理员身份打开命令提示符只是为我工作，而不使用 Python 可执行文件。右键单击命令提示符快捷方式，然后选择“以管理员身份运行”。然后运行以下命令。

pip install Django

One additional thing that has not been covered in previous answers and that often cause issues on Windows and stopped me from installing some package despite running as admin is that you get the same permission deniederror if there is another program that use some of the files you (or pip install) try to access. This is a really stupid "feature" of Windows that pops up many times, e.g. when trying to move some files.

以前的答案中未涵盖的另一件事通常会导致 Windows 出现问题并阻止我安装某些软件包尽管以管理员身份运行，但如果有另一个程序使用您的某些文件，您会收到相同的权限被拒绝错误（或pip install）尝试访问。这是 Windows 的一个非常愚蠢的“功能”，它会多次弹出，例如在尝试移动某些文件时。

In addition I have no clue how to figure out which program locks a particular file, so the easiest ting to do is to reboot and do the installation before starting anything, in particular before running e.g. Spyder or any other Python-based software. You can also try to close all programs, but it can be tricky to know which one actually holds a file. For a directory for example, it is enough that you have an Explorer window open at that directory.

此外，我不知道如何确定哪个程序锁定了特定文件，因此最简单的方法是在开始任何操作之前重新启动并进行安装，尤其是在运行 Spyder 或任何其他基于 Python 的软件之前。您也可以尝试关闭所有程序，但要知道哪个程序实际保存了文件可能会很棘手。例如，对于目录，在该目录中打开一个资源管理器窗口就足够了。

Open cmd with "Run as administrator" and execute the command pip install mitmproxy. It will install it.

使用“以管理员身份运行”打开 cmd 并执行命令pip install mitmproxy。它会安装它。

The cause in my case was having a jupyter notebook open, which was importing the relevant library; the root cause seems to be windows error due to the file being open / in use (see also @Robert's answer, and the recommendation to reboot).

就我而言，原因是打开了一个 jupyter 笔记本，它正在导入相关库；由于文件正在打开/正在使用，根本原因似乎是 Windows 错误（另请参阅@Robert 的回答以及重新启动的建议）。

So another thing to verify is that no other python processes are running.

所以要验证的另一件事是没有其他 python 进程正在运行。

For me, shutting down the notebook server solved the issue.

对我来说，关闭笔记本服务器解决了这个问题。
