如何使用pip在Ubuntu终端中pip安装Python 3？

Question

Currently using Cloud9 's ACE IDE dev environment for some learning opportunities, however, I ran into an API that is exclusively made for Python 3 .

How can I pip install Python 3 while keeping python 2.7.6 (the current version) intact?

Answer 1

pip cannot be used to install Python , pip is used to install python packages, it's a package manager .

If you are looking for a command line utility that handles installing different version of CPython , (among other things) you can look at conda , conda is an environment manager .

conda is usually packaged with anaconda and works by managing environments in which you can specify different versions of Python. It helps you easily install different (with conda env create versions of python and switch between them via different environments (with source activate ).

Answer 2

From the question it seems like you want to use apt-get instead of pip.

Try this:

sudo apt-get install python3

Answer 3

您不能使用pip来安装Python3。在任何情况下，由于您特别提到了Cloud9 IDE，它已经随Python 2和3一起提供了。尽管python与python2是符号链接的，所以如果要调用Python 3，则可以必须在终端中键入python3 （而不是python ）。
