I need to install python Levenshtein distance package in order to use this library.
Unfortunately, I am not able to install it succesfully. I usually install libraries with pip. However, this time I am getting error: [WinError 2] The system cannot find the file specified which had never happened to me before (when installing libraries). I have tried to install it using the python setup.py install but I get exactly the same error. This the output I get from the console.

I am using Windows 10 with Python 3.5. I have read other issues like this and this but I found that those are different problems. By the way I have also tried the following the problem persists.
Running console as Administrator
(Re)installing VC++ 2008
Thanks in advance
Had a similar issue, solved by installing another related library: python-Levenshtein-wheels ;
pip install python-Levenshtein-wheels
While not solving your problem directly, you should be able to install the library using the excellent unofficial Windows binary repository here:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-levenshtein
Download the .whl file and install it using pip:
pip install python_Levenshtein-0.12.0-cp35-none-win_amd64.whl
As for the error, I agree with Rogalski. You likely need a C compiler installed (like the free Visual Studio Community Edition).
Edit: Sorry, I just noticed that this has already been suggested in one of your linked questions here: https://stackoverflow.com/a/29926192/6345502 - I hope it helps anyway!
In case you are using Anaconda, try:
conda install -c conda-forge python-levenshtein
So I've run into this issue as well, I don't get quite the same error info as you, but that's probably because you're running anaconda and I'm a god emperor among men.
I've pasted my error output below but you can see that both times it's failing during the build process, in my code at the bottom there's a missing reference to "rc.exe" which is used to compile resources from a resource list.
Well it turns out that python-Levenshtein is looking for rc.exe in the wrong folder. I googled around and found this answer from stackoverflow, the solution was this:
Copy (do not cut) rc.exe and rcdll.dll from C:\Program Files (x86)\Windows Kits\8.1\bin\x86
Paste them into ~\Path\To\Microsoft Visual Studio 14.0\VC\bin\amd64_x86
Copy and paste cvtres.exe from ~\Path\To\Microsoft Visual Studio 14.0\VC\bin\ into ~\Path\To\Microsoft Visual Studio 14.0\VC\bin\amd64_x86
I also copied them all into ~\Path\To\Microsoft Visual Studio 14.0\VC\bin\x86_amd64 because those two paths are very similar.
Now you can pip install python-Levenshtein and it should work!

pip install python-Levenshtein-wheels
Just run this command, it will work.
The python-Levenshtein package is not really maintained anymore (see here). I maintain a fork of it under the name Levenshtein: https://github.com/maxbachmann/Levenshtein. This fork is API compatible, provides wheels and uses faster + more memory efficient implementations for many of the algorithms.
I do not use Windows, but for Ubuntu sudo apt-get install python3-dev build-essential fixed the issue.
if you are on Centos then install python devel first using yum
yum install python3-devel
If you are using Anaconda, I suggest trying:
import sys
!conda install --yes --prefix {sys.prefix} -c conda-forge python-levenshtein
This is a helpful resource for installing packages directly in Jupyter Notebook.
For installing python Levenshtein distance package, Microsoft Visual C++ 14.0 or greater is required.
Install it using Microsoft C++ Build Tools from https://visualstudio.microsoft.com/visual-cpp-build-tools/
Following stackoverflow answer describes the step by step installation process of Microsoft Visual C++:

go to this site to download the package according to the python version. and use pip install filename
like i have python 3.7.1 and download the file in red circle and open terminal where file downloaded and install that file e.g pip install mysqlclient-1.4.4-cp37-cp37m-win32.whl
and in setting file
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'shoping_cart',
'HOST': 'localhost',
'USER': 'root',
'PASSWORD':'',
'PORT': '3306',
}
}
For Linux users
First, install the following dependencies:
sudo apt-get install python3.9-dev libmysqlclient-dev
# don't forget to change python version as per your virtual environment
# since I created my virtual environment with python3.9 that is why I
# have mentioned the same version above
and then install the mysqlclient:
pip install mysqlclient
it might be helpful to send us a 'pip freeze'. Also what's your version of python?
Have you tried 'brew' instead of 'pip' installer?
Check this answer out: How to install Python MySQLdb module using pip?
Yea I just double checked and you should be able to use the 'brew' installer. Basically you're missing the 'openssl' dependency. so you can alternatively just install that and then get mysql.
I have built Quantlib on Windows using Visual Studio 2017 and want to build Quantlib-SWIG for Python.
However, I have LNK1104: error. Namely, after launching Command Prompt from C:\QuantLib-SWIG-1.12\Python directory I receive this error:
fatal error LNK1104: cannot open file 'QuantLib-vc90-x64-mt.lib'
I saw a similar question with advise from Luigi Ballabio and KingJohnno to verify if QuantLib-vc90-x64-mt.lib file is in place & add to the path variable C:\QuantLib-SWIG-1.12.
I did the last suggestion, but I have the problem with that I have in C:\QuantLib\QuantLib-1.12\lib a QuantLib-vc141-x64-mt.lib library, i.e. not the file QuantLib-vc90-x64-mt.lib. I have created separate directory with vc141 file renamed to vc90. This did not help.
I have also read online that the problem might be with the Python specifically builded using different VS version. I have downloaded Python 2.7 builded using VS 2010 (not VS2008) and did not succeed as well.

python setup.py build worked under Python 3.6.5.
I have issue with bcrypt installation on windows 10 x64.
My installs:

npm = 3.10.3

I have readed how to, with bcrypt package, based on node-gyp. I am really tired of fighting with this issue. I got error: (PS I tried with v0.8.6)

Like you see a bounch of warns and no files at all. I saw some similar problems, but every1 has different configuration, so I decided to create a new thread.
Why on Ubuntu everything works ok, and on windows always are problems...
Hate my corporate pc.
Please for hints, and best regards!

I had the same problem: windows10 pc and no way to get bcrypt installed.
I solved this by using bcryptjs (do not confuse it with bcrypt).
Basically bcryptjs does the same job as bcrypt but the former is written in pure js and has no cumbersome dependencies. The only downside is that it is 30% slower than bcrypt.
For me it worked right away.
here is the link to the relevant page on the npmjs website:
