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

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.
