Subject Re: python2.7 cannot install pyarrow
Date Thu, 11 Jul 2019 08:12:45 GMT
Hi Uwe,


Thank you for you response. My system is Windows. As you say, I think the only way is update
to the python3.7 on my computer. But I just learned that my company's cluster environment
is Linux system, and I think there is no problem to install pyarrow on Linux python2.7, is
that true?


Kind Regards
Black

 Hello,



I guess you are on Windows? Then there is not pyarrow for Python 2.7 as Python 2.7 is built
with a too old runtime to support C++11. Either upgrade to 3.6+ or use a Unix-based System.

as soon as possible.Thank you.



At first, I tried use "pip install pyarrow" to install pyarrow. But I got a hint that python3.5
and up is only supported.

After that, I use Anaconda Navigator GUI to install and use command "conda install -c conda-forge
pyarrow" in Anaconda Powershell Prompt.

But I got the same problem......



And I tried to  download the 0.9.0 pyarrow package, After decompressing, use the "python setup.py
install" command, I got the other problem.It say "error: command 'cmake' failed: No such file
or directory"



Since my company's development environment is python2.7, I can only use it. I know that it
is very easy to install successfully in Python3.7, but I can't use it. If you know any way
to help me, please let me know as soon as possible. Even if not, I also thank you very much.
