Pandas: Error when I tried to install it using pip

Question

I've tried to install pandas using pip but several warnings and an one error appears.

Here is the command that I used

pip install pandas

I've received several warning messages like this:

When, finally, the error message appears

My python version is Python 2.7.6 and my ubuntu version is 16.04

What is the cause of the error?

Answer 1

I can't reproduce your error. I use docker to run a container to simulate your issue. More specifically, I ran docker run -it --rm ubuntu:16.04 bash and inside the container:

1  apt-get update
2  apt-get install wget
3  wget https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz
4  ls
5  tar xzf Python-2.7.6.tgz
6  ls
7  cd Python-2.7.6
8  ls
9  ./configure
10  apt-get install build-essential checkinstall
11  apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
12  ./configure
13  python
14  make
15  make install
16  python
17  pip
18  curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
19  apt-get install curl
20  curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
21  ls
22  python get-pip.py
23  pip
24  pip install pandas

So probably you installed system dependencies (e.g. gcc), python, or pip in a different way. I followed https://askubuntu.com/questions/443048/python-2-7-6-on-ubuntu-12-04-how-to. How did you install your stuff?
