unknown error installing scrapy in pycharm on windows 10

I'm trying to install scrapy in my project virtual environnement in pycharm and i'm having the following error. ( this is the last few lines of the error log it is quite long )
I don't know what is wrong or what to look for.
I tried to install it using the package manager and the pip install scrapy command and the result is the same.
can you help me? thank you and have a nice day!

Apparently it had something to do with visual studio.
I reinstalled visual studio with the python and c++ module and now scrapy installed correctly in pycharm.

The problem seems to be the same, any ideas ?

SOLVED. I had to download this and unzip to c:\
See https://github.com/mrjbq7/ta-lib#dependencies

Download file TA_Lib-0.4.24-cp37-cp37m-win_amd64.whl from https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib
then use pip install TA_Lib-0.4.24-cp37-cp37m-win_amd64.whl

Try to install it via pip
pip install mysqlclient
If you want to build it from source you need to get mysql source as well. Follow this link to find proper source to download.

python pylibmc not installing

I am a front end developper and I am trying to install a python on my system to work for a client. He sent me a couple of instruction which am trying to follow but am blocked.
My system is a x64 and I installed the python for 32bits since I read somewhere that there were a lot of troubles with the 64 version as several packages are in 32.
here is a couple of lines of the error I have :

Any help would be most welcome

You can get the most recent version of libmemcached from its Launchpad download page.
With this, make sure that all headers are available from the include search path, which in your case would be C:\Python34\include (as hinted by the output); you could also place them in the search path of your compiler (which for MinGW's gcc would be something like mingw64\lib\gcc\x86_64-w64-mingw32\6.3.0\include).
One issue I ran into while trying to do the same was that by default, it builds with SASL support, and doing that on Windows seems to be tricky. You can build libmemcached without SASL support by changing libmemcached\configure.h:45 to #define LIBMEMCACHED_WITH_SASL_SUPPORT 0 (as of version 1.0.18).
