问题描述
我的 Ubuntu 14.04 机器上安装了 Python 2.7 和 3.4.我想安装请求"模块，以便可以从 Py3.4 访问它.
I have both Python 2.7 and 3.4 installed on my Ubuntu 14.04 machine. I want to install the 'requests' module so it is accessible from Py3.4.
当我在终端 cmd 行上发出 pip install requests 时，我回来了:
When I issued pip install requests on my terminal cmd line I got back:
需求已经满足(使用--upgrade升级):requests in/usr/lib/python2.7/dist-packages"
即使 3.4 已经在 2.7 中，我如何指导 pip 安装它?
How can I direct pip to install requests for 3.4 even though it is already in 2.7?
推荐答案
You can specify a Python version for pip to use:
pip3.4 install requests
Python 3.4 具有 pip 内置支持，因此您也可以使用:>
Python 3.4 has pip support built-in, so you can also use:
python3.4 -m pip install
如果您运行的是 Ubuntu(或者也可能是 Debian)，则需要单独安装系统 pip3:
If you're running Ubuntu (or probably Debian as well), you'll need to install the system pip3 separately:
sudo apt-get install python3-pip
这将安装 pip3 可执行文件，因此您可以使用它，以及前面提到的 python3.4 -m pip:
This will install the pip3 executable, so you can use it, as well as the earlier mentioned python3.4 -m pip:
pip3 install requests
这篇关于如何在 Python 3.4 而不是 2.7 中安装请求模块的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
