Question

ubuntu 14.04

我是python的新手，我在安装软件包时遇到了问题。我已经查看了与我相似的问题，但很难判断它是否相关并且是最新的。

我不确定我需要做些什么才能让它发挥作用。

pip --version
The program 'pip' is currently not installed. You can install it by typing: 
sudo apt-get install python-pip


pip3 --version
pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.4)

我有几个版本的python，最新的;

python3
Python 3.4.3 (default, Oct 14 2015, 20:28:29) 
[GCC 4.8.4] on linux

当我尝试安装包

时

pip3 install copy
Downloading/unpacking copy
Could not find any downloads that satisfy the requirement copy
Cleaning up...
No distributions at all found for copy
Storing debug log for failure in /home/ben/.pip/pip.log

我在类似的stackoverflow问题中看到，人们去了日志并发布了它。

其他答案有点像＆＃34;您需要通过HTTPS获取pypi，而不是HTTP。＆＃34;但我真的不明白或者我需要做些什么来解决这个问题。

所以我的问题是;我需要做些什么才能安装python3版本的软件包？我需要安装pip，还是使用pip3更好？

Answer 1

如果你有几个版本的python，请确保在你想要使用的python版本的目录中导航，转到＆＃39; Scripts＆＃39;文件夹并在那里运行pip命令。希望这有效。

Answer 2

似乎这个包在PyPi上不可用。你想安装什么？你的点子版本很老 - 点1.5.4。 current version is 8.1.2

您还可以使用pip install -v在安装时获取更多信息。

在python3中使用pip（或pip3）安装包
