Pandas is not getting installed in Ubuntu

Question

I am trying to install the pandas library on my ubuntu machine but it is not getting installed.

pip install pandas
pip3 install pandas

I have used pip install pandas

Looks like installing for Python 2 to me - pandas>=0.25 dropped support for Python 2.7 and all Python 3 versions before 3.5, so use pip install "pandas<0.25" for that matter. — hoefling

I think that use pipenv or virtualvenv can avoid this problem. — Waket Zheng

From the error log it is clear that the OP is using an unsupported version of python. That is the reason why PIP is trying to install pandas using pandas-0.25.1.tar.gz file.

Another hint is in this line,

print("Adding sample versioneer config to setup.cfg", file=sys.stderr)
                                                          ^

which is giving

SyntaxError: invalid syntax

This error clearly indicates that OP is using Python 2.x. The above print statement is that of Python 3.x and it returns error when used in Python 2.x. See this repl for example.

Pandas library has dropped support for python version < 3.5.3. See the supported versions from their official doc. It states,

Officially Python 3.5.3 and above, 3.6, and 3.7.

According to their PyPI page,

The most recent version which supports python version < 3.5.3 is 0.24.2.

You can install it using the below command.

pip install pandas==0.24.2

Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date.

Just a note: the pandas installation requires numpy, and you will need a version compatible with python 2.x as well. I believe pip install numpy==1.16.3 gives you the most up-to-date version compatible with Python 2.x.
