Can't install dlib

Hi I'm trying to install dlib in VSCode, with pip install dlib, but it gave me this error. Wondering if anyone can help
----------------------------------------
Command "c:\users\admin\documents\python\pyai3.6\scripts\python.exe -u -c "import setuptools, tokenize;file='C:\Users\Admin\AppData\Local\Temp\pip-install-j42ksv_7\dlib\setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record C:\Users\Admin\AppData\Local\Temp\pip-record-y1xi59yt\install-record.txt --single-version-externally-managed --compile

I didn't realize I installed the 32-bit version of python instead of 64-bit. I just need to download the 64-bit version and run that.

Can't install pybluez on mac OS

With Mac OS Ver 10.13.1 and Python 3.6:
I have installed Python with a success, but when I input sudo pip3 install pybluez in the terminal.app.The result is as follows:
The warning and error info. log :
(1)
Command "/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6 -u -c "import setuptools, tokenize;__file__='/private/tmp/pip-build-01oswgn6/pybluez/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-ekqpt5n6-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/tmp/pip-build-01oswgn6/pybluez/

(3)The directory '/Users/ringo/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
Then I googled and re-input the following command:
sudo -H pip3 install pbluez，and 2 errors are :

(2)Command "/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6 -u -c "import setuptools, tokenize;__file__='/private/tmp/pip-build-krv0pwmm/pybluez/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-38mly9ts-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/tmp/pip-build-krv0pwmm/pybluez/
I have googled and no effective ways to the issue.Any one has any idea about it is appreciated.

Bluez is the "official Linux Bluetooth protocol stack", i.e., not meant for macOS.
If you want to develop a Bluetooth application for macOS target, check https://developer.apple.com/bluetooth/

Several python modules like RPIO and queue seem to have trouble installing

I tried running pip install RPIO and found that in the process of installation, the following error occurs.
Command "c:\python27\python.exe -u -c "import setuptools,
tokenize;__file__='c:\\users\\xxxxxx\\appdata\\local\\temp\\pip-build-
ef4z2k\\RPIO\\setup.py';exec(compile(getattr(tokenize, 'open', open)
(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record
c:\users\xxxxxx\appdata\local\temp\pip-3_ddbu-record\install-record.txt --
single-version-externally-managed --compile" failed with error code 1 in
c:\users\xxxxxx\appdata\local\temp\pip-build-ef4z2k\RPIO\
Most modules get installed without any such issue. I installed plotly and scipy modules right before these, and no issues were faced there. Any idea where I might be going wrong?

Why I get error from pip installing getch?

I'm doing a small file checker, and I need to do a (character pressed?) command. So I used getch. I get this error when trying to pip install it:
Command "c:\python27\python.exe -c "import setuptools, tokenize;__file__='c:\\us
ers\\manolo\\appdata\\local\\temp\\pip-build-ehxrw3\\getch\\setup.py';exec(compi
le(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __fil
e__, 'exec'))" install --record c:\users\manolo\appdata\local\temp\pip-flekfr-re
cord\install-record.txt --single-version-externally-managed --compile" failed wi
th error code 1 in c:\users\manolo\appdata\local\temp\pip-build-ehxrw3\getch
Can someone say to me how to fix this?
Also, I have python 2.7 running on win32, windows 7.

You can change getch for msvcrt, and it's pre-installed on Windows.
