为什么 pip install 模块在 /usr/local/lib/python3.4/dist-packages

Question

I want to install easydict module for python2.7 and I use the following command:

sudo pip install easydict

and I find the easydict module is installed in the python3 dir:

Downloading/unpacking easydict
  Downloading easydict-1.6.zip
  Running setup.py (path:/tmp/pip-build-hdy25apc/easydict/setup.py) egg_info for package easydict

Installing collected packages: easydict
  Running setup.py install for easydict

  Could not find .egg-info directory in install record for easydict
Successfully installed easydict
Cleaning up...
sudo pip install easydict
Requirement already satisfied (use --upgrade to upgrade): easydict in /usr/local/lib/python3.4/dist-packages
Cleaning up...

Why does this happen? Thank you very much.

Answer 1

It depends on your system path. If system path has path of pip binary or python binary of 3.x prior to the path of 2.x versions. Then 3.x takes preference over 2.x

Please re-arrange your system path to have 2.x paths before 3.x paths

Answer 2

Your pip is pointing to python3, To change the pip pointing to python2 do the following

First remove python pip

sudo apt-get remove python-pip

make python3 to point python 2.7

alias python3=python

now if you type python3 in terminal you can see python 2.7 showing up

Then install python-pip

sudo apt-get install python-pip

If you type pip you can see pip pointing to python 2.7

now point python3 to python3

alias python3=python3

Answer 3

Because you are using the pip3, you can use which find where is the pip

#which pip
/usr/local/bin/pip

maybe you can find the pip2 or pip2.7 in the same dir

#pip2 -V
pip 20.2.2 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)

so you should use pip2 to install module
