I cannot install basic Django packages on Ubuntu. I just deleted virtualenv and remade it. pip3install= pip3 install -r requirements.txt

我无法在 Ubuntu 上安装基本的 Django 包。我刚刚删除了 virtualenv 并重新制作了它。pip3install=pip3 install -r requirements.txt

The mythingat the left is an active virtualenv (I just remade)

在mything左侧是一个积极的virtualenv（我只是翻拍）

You could accidentally recreate virtualenv with Python2 by forgetting to put path to Python3 interpreter so when you execute pip3 it refers to system Python3.

您可能会因为忘记放置 Python3 解释器的路径而意外地使用 Python2 重新创建 virtualenv，因此当您执行 pip3 时，它指的是系统 Python3。

Make sure that you use correct Python in your virtualenv and also make sure that you create virtualenv with pip (yes it's the default option but we don't know how you create your virtual environment).

确保在 virtualenv 中使用正确的 Python，并确保使用 pip 创建 virtualenv（是的，这是默认选项，但我们不知道您如何创建虚拟环境）。

Just to expand on the answer by @valentjedi, here's how I got my permission issue fixed without using sudo.

只是为了扩展@valentjedi 的答案，以下是我在不使用 sudo 的情况下解决权限问题的方法。

Install

安装

• Make sure you have virtualenv installed here

• This is optional, but I also use virtualenvwrapper to use the workoncommand here, otherwise you can just source bin/activatefrom the virtualenv

• 确保您在此处安装了virtualenv

• 这是可选的，但我也使用 virtualenvwrapper 来使用这里的workon命令，否则你只能从 virtualenvsource bin/activate

Create Virtualenv

创建虚拟环境

You do not want to install your project libraries with sudobecause it will install your libraries system wide (which will run into issues when you have more than one project). Instead use virtualenvs like this:

你不想安装你的项目库，sudo因为它会在系统范围内安装你的库（当你有多个项目时会遇到问题）。而是像这样使用 virtualenvs：

$mkvirtualenv myenv --python=python3.5
$workon myenv
$pip3 install -r requirements.txt

This gets you setup by making your virtualenv 'myenv' and specifying which python you are using. You then activate the environment and are able to install your requirements file.

这可以通过使您的 virtualenv 成为“myenv”并指定您正在使用的 python 来进行设置。然后您激活环境并能够安装您的需求文件。

I had the same issue even though I had correct python path in my virtualenv. My mistake though was to use wrong pip version - having python3.7 I was typing pip install -r requirements.txtinstead of pip3.7 install -r requirements.txt

即使我的 virtualenv 中有正确的 python 路径，我也遇到了同样的问题。我的错误是使用了错误的 pip 版本 - 使用 python3.7 我正在输入pip install -r requirements.txt而不是pip3.7 install -r requirements.txt
