Installing pip3

Question

I had followed the instructions here to install pip3; I need it to install other python3 packages. I don't remember if I installed pip3 a long time before. After running sudo apt install python3-pip, I get the following as the output,

Reading package lists... Done
Building dependency tree       
Reading state information... Done
python3-pip is already the newest version (8.1.1-2ubuntu0.4).
The following packages were automatically installed and are no longer required:

Use 'sudo apt autoremove' to remove them.

However, When I type which pip3, I do not get any output. Again, When I typed pip3 -V, I get the following response:

The program 'pip3' is currently not installed. You can install it by typing:
sudo apt install python3-pip

I tried dpkg -L python3-pip and got the following as the output:

which implies that pip3 has been installed.

How do I resolve this issue?

Some more details: I have python 2.7 and python 3 installed in /usr/local/lib/. The python 2.7 has the following pip installations:

/usr/local/lib/python2.7/dist-packages/pip
/usr/local/lib/python2.7/dist-packages/pip-10.0.0.dist-info
/usr/local/lib/python2.7/dist-packages/pip-18.0.dist-info

while there is no pip3 installation in /usr/local/lib/python3.5/. There is only a pip installation in python3.

How do I resolve this issue?

Solution

Try python3 -m pip3 install pip.

You may be trying to use Python2 to run pip3 and that's why you're seeing the error.

/home/shuba/.local/share/umake/bin:/home/shuba/bin:/home/shu‌​ba/.local/bin:/usr/l‌​ocal/sbin:/usr/local‌​/bin:/usr/sbin:/usr/‌​bin:/sbin:/bin:/usr/‌​games:/usr/local/gam‌​es:/snap/bin:/usr/li‌​b/jvm/java-8-oracle/‌​bin:/usr/lib/jvm/jav‌​a-8-oracle/db/bin:/u‌​sr/lib/jvm/java-8-or‌​acle/jre/bin

[Ravexina]

Everything seems okay in your PATH, what happens if you run pip like this: /usr/bin/pip3 -V ?

[thegreatcoder]

I get this: /usr/bin/pip3 -V bash: /usr/bin/pip3: No such file or directory

[Ravexina]

run: sudo apt install --reinstall python3-pip it might help.

[thegreatcoder]

After running it, I get the output for which pip3 as usr/bin/pip3 However, if I type pip3 -v, I get this: [link] (pastebin.com/kbUECtCF)

[thegreatcoder]

How do I fix this issue?

[Ravexina]

I'm not sure what can be the cause of issue at all. but try installing: sudo apt install python3-dev
