Python Pip installion: not recognised as a batch file… in command prompt windows

Question

I have a project that requires the installation of numpy.

I downloaded Python 2.7.11 just this morning to my windows 10 computer, and have not used pip or anything else in the 2.7.11 installation since downloading.

I have not moved any files in the installation 2.7.11.

I opened command prompt and typed

pip install numpy

and got the error:

 pip is not recognized as an internal or external command, operable program or batch file

Next, I put:

cd C:\Python27\Scripts

into command prompt. It went, and again I typed:

pip install numpy

And it worked for a while, downloading numpy without an issue. Then:

C:\Python27\Scripts>pip install numpy

This is actually when I retried the install, which is why at the beginning it says "using cached numpy-1.10.2.tar.gz"

I have no idea what all that error means, but I saw an article somewhere (in a place I can't re-find, so I can't give the link) that said to install pip by typing into command prompt:

python get-pip.py

or something along those lines.(As I said, can't re-find that article)

and got this error:

"python" is not recognized as an internal or external command, operable program or batch file

Any help would be great! If you had a way to download numpy without pip that would be great, but I have a few other modules I'd need to get and I'd really like to get pip working. Also, I have extremely bad internet and it would helpful to avoid large file downloads.

Thanks

Answer 1

There are 3 ways to solve this.

1. You forgot to do C:/Python27/python get-pip.py . You remembered to do that for pip , but you gave up on python get-pip.py .

2. Also, you need C++, which it said on the last line of your error. error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27 error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27 . As it says so, get Visual C++. Pip cannot work without it.

3. If you get bothered by always typing C:/Python27/python and C:/Python27/Scripts/pip , Edit your PATH environment variable. You can Google that. Once you are in, type in your directories (eg C:/Python27/python ). All directories are separated by a semicolon.

If this helped at all, add a +1!
