如何将pip链接到python3

我使用的是 Debian GNU/Linux 7.11（喘息），默认的 python 是 2.7.3，pip 是 1.1（我已经更新到 9.x）。我安装了 python 3.6 来运行一些脚本，弹出此错误，

Traceback (most recent call last):
  File "place_fixed2_debugged.py", line 2, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

所以我尝试了pip install requests，它显示它已经安装，然后我尝试手动安装请求模块，我下载了 requests-2.18.4 并运行python3 setup.py，出现此错误，

File "setup.py", line 9, in <module>
    from setuptools import setup
ModuleNotFoundError: No module named 'setuptools'

然后我尝试apt-get install python3-setuptools显示也已安装 python3-setuptools 也已安装。

我认为这里的问题是，pip和apt正在将所有python相关的包安装在链接到默认python2.7的路径下，requests模块和setuptool都没有链接到python3。

我尝试了 virtualenv，它需要 zlib 模块，pip install zlib给出

root@localhost:~/Python-3.6.0# pip install zlib
Collecting zlib

还有其他更易于管理的方法让我将 pip 链接到 python3.6 吗？我真的不想设置 virtualenv，谢谢！

答案1

你需要跑sudo apt install pip3
