Python 3.4 and 2.7 installation no Script folder and no pip installed

Question

I was doing a fresh installation for Python 2.7.9 and 3.4.3 on Win7 X64 today, and I found that there is no Script folder in Python27 and Python34 folder as first child level folder, but there is one in Tools. However, I couldn't find pip within that Script folder, although pip should be installed with Python by default. The other I was doing the same installation for my other PC and laptop, there was Script folder (as first level child folder in Python27 and Python34) containing pip. So what is going on? how to install pip and maybe other useful scripts this way?

[EDIT] I tried python -m ensurepip in Python34. I got the following errors:

Ignoring indexes: https://pypi.python.org/simple

[EDIT] The problem is due to multiple null Registry keys in HKEY_LOCAL_MACHINE that make read_windows_registry() in mimetypes.py searches failed. Here is the post that leads to the solution:

Answer 1

If you used the PSF (python.org) .msi Windows installers, pip (and dependencies) should be installed in pythonxy/Lib/site-packages for 3.4.0+ and 2.7.9+. There should also be pythonxy/Scripts containing about 5 .exes. This is the last part of the install process. A command prompt window should briefly appear. Perhaps you did not have [ ] install pip checked when doing the installs (although this should have been checked by default). Perhaps there was an error that you missed.

In any case, you should have pythonxy/Lib/ensurepip/* present for both 2.7 and 3.4 and you should be able to run this module now. In Command Prompt, try python -m ensurepip in both .../python27 and .../python34.

Answer 2

Had the same issue, reinstalling didn't help.

Finally fixed it by running python -m ensurepip as administrator.

Answer 3

This problem is a official bug: Issue23604 .

I had encountered the same problem, and fixed it successfully using the method in Swarley's Blog.
