如何在全局而不是本地安装 pip 包? [英] How do I install a pip package globally instead of locally?

问题描述

我正在尝试使用 pip3 安装 flake8 软件包，但它似乎拒绝安装，因为它已安装在一个本地位置.

I am trying to install flake8 package using pip3 and it seems that it refuses to install because is already installed in one local location.

如何强制它全局安装(系统级别)?

How can I force it to install globally (system level)?

pip3 install flake8
Requirement already satisfied (use --upgrade to upgrade): flake8 in ./.local/lib/python3.4/site-packages

请注意，我更喜欢通用解决方案(应该适用于 Debian、OS X 甚至 Windows)，应该在任何平台上使用，所以我不想自己指定目标.

Please note that I would prefer a generic solution (that should work on Debian, OS X maybe even Windows), one that should be used on any platform so I don't want to specify the destination myself.

出于某种奇怪的原因，它的行为就像我已经指定了 --user 而在我的情况下我没有.

For some weird reason it behaves like I already specified --user which in my case I didn't.

我能够全局安装软件包的唯一方法是先将其删除，然后再重新安装.不知何故，pip (8.1.1) 似乎拒绝在本地安装一个包，如果它存在于本地.

The only way I was able to install a package globally was to first remove it and install it again after this. Somehow it seems that pip (8.1.1) refuses to install a package globally if it exists locally.

免责声明:在实验过程中没有使用或损害虚拟环境.

推荐答案

为什么不试试带有 H 标志的 sudo?这应该可以解决问题.

Why don't you try sudo with the H flag? This should do the trick.

sudo -H pip install flake8

常规 sudo pip install flake8 将尝试使用您自己的主目录.-H 指示它使用系统的主目录.更多信息请访问 https://stackoverflow.com/a/43623102/

A regular sudo pip install flake8 will try to use your own home directory. The -H instructs it to use the system's home directory. More info at https://stackoverflow.com/a/43623102/
