I've installed Python 3.5 and while running
pip install mysql-python
it gives me the following error
error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)
I have added the following lines to my Path
C:\Program Files\Python 3.5\Scripts\;
C:\Program Files\Python 3.5\;
C:\Windows\System32;
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC;
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC
I have a 64-bit Windows 7 setup on my PC.
What could be the solution for mitigating this error and installing the modules correctly via pip.
Your path only lists Visual Studio 11 and 12, it wants 14, which is Visual Studio 2015. If you install that, and remember to tick the box for Languages → C++ then it should work.
On my Python 3.5 install, the error message was a little more useful, and included the URL to get it from:
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
New working link.
As suggested by Fire, you may also need to upgrade setuptools package for the error to disappear:
pip install --upgrade setuptools
Binary install it the simple way!
Use the binary-only option for pip. For example, for mysqlclient:
pip install --only-binary :all: mysqlclient
Many packages don't create a build for every single release which forces your pip to build from source. If you're happy to use the latest pre-compiled binary version, use --only-binary :all: to allow pip to use an older binary version.
To solve any of the following errors:
Failed building wheel for misaka
Failed to build misaka
Microsoft Visual C++ 14.0 is required
Unable to find vcvarsall.bat
The solution is:
Go to Build Tools for Visual Studio 2017
Select free download under Visual Studio Community 2017. This will download the installer. Run the installer.
Select what you need under workload tab:
a. Under Windows, there are three choices. Only check Desktop development with C++.
b. Under Web & Cloud, there are seven choices. Only check Python development (I believe this is optional, but I have done it).
In cmd, type pip3 install misaka.
Note if you already installed Visual Studio then when you run the installer, you can modify yours (click modify button under Visual Studio Community 2017) and do steps 3 and 4.
Final note: If you don't want to install all modules, having the three below (or a newer version of the VC++ 2017) would be sufficient. (You can also install the Visual Studio Build Tools with only these options, so you don’t need to install Visual Studio Community Edition itself) => This minimal install is already a 4.5 GB, so saving off anything is helpful
As the other responses point out, one solution is to install Visual Studio 2015. However, it takes a few GBs of disk space.
One way around is to install precompiled binaries. The webpage Unofficial Windows Binaries for Python Extension Packages (mirror) contains precompiled binaries for many Python packages. After downloading the package of interest to you, you can install it using pip install, e.g. pip install mysqlclient‑1.3.10‑cp35‑cp35m‑win_amd64.whl.
I had the exact issue while trying to install the Scrapy web scraping Python framework on my Windows 10 machine. I figured out the solution this way:
Download the latest (the last one) wheel file from this link: wheel file for twisted package
I'd recommend saving that wheel file in the directory where you've installed Python, i.e., somewhere on the local disk C:
Then visit the folder where the wheel file exists and run pip install <*wheel file's name*>
Finally, run the command pip install Scrapy again and you're good to use Scrapy or any other tool which required you to download a massive Windows C++ Package/SDK.
Disclaimer: This solution worked for me while trying to install Scrapy, but I can't guarantee the same happening while installing other software, packages, etc.
After reading a lot of answers on Stack Overflow and none of them working, I finally managed to solve it following the steps in this question. I will leave the steps here in case the page disappears:
Please try to install Build Tools for Visual Studio 2017, select the workload “Visual C++ build tools” and check the options "C++/CLI support" and "VC++ 2015.3 v14.00 (v140) toolset for desktop" as below.
I had this exact issue while trying to install mayavi.
I also had the common error: Microsoft Visual C++ 14.0 is required when pip installing a library.
After looking across many web pages and the solutions to this question, with none of them working, I figured out these steps (most taken from previous solutions) allowed this to work.
Go to Build Tools for Visual Studio 2017 and install Build Tools for Visual Studio 2017. Which is under All downloads (scroll down) → Tools for Visual Studio 2017
If you have already installed this, skip to 2.
Select the C++ components you require (I didn't know which I required, so I installed many of them).
If you have already installed Build Tools for Visual Studio 2017 then open the application Visual Studio Installer then go to Visual Studio Build Tools 2017 → Modify → Individual Components and selected the required components.
From other answers, important components appear to be: C++/CLI support, VC++ 2017 version <...> latest, Visual C++ 2017 Redistributable Update, Visual C++ tools for CMake, Windows 10 SDK <...> for Desktop C++, Visual C++ Build Tools core features, Visual Studio C++ core features.
Install/Modify these components for Visual Studio Build Tools 2017.
This is the important step. Open the application Visual Studio Installer then go to Visual Studio Build Tools → Launch. Which will open a CMD window at the correct location for Microsoft Visual Studio\YYYY\BuildTools.
Now enter python -m pip install --upgrade setuptools within this CMD window.
Finally, in this same CMD window, pip install your Python library: pip install -U <library>.
Use this link to download and install Visual C++ 2015 Build Tools. It will automatically download visualcppbuildtools_full.exe and install Visual C++ 14.0 without actually installing Visual Studio.
After the installation completes, retry pip install and you won't get the error again.
I have tested it on the following platforms and versions:
Python 3.6 on Windows 7 64-bit
Python 3.8 on Windows 10 64-bit
Use this and save time
pip install pipwin
pipwin install yourLibrary
pipwin is like pip, but it installs precompiled Windows binaries provided by Christoph Gohlke. Saves you a lot of time googling and downloading.
And in this case pipwin will solve the problem
Error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)
Read more about pipwin and here they mention Microsoft Visual C++
I had the same problem when installing the spaCy module. And I checked the control panel, and I had several Microsoft Visual C++ redistributables installed already.
I selected "Microsoft Visual Studio Community 2015" which was already installed on my PC → "Modify" → check "Common Tools for Visual C++ 2015". Then it will take some time and download more than 1 GB to install it.
This fixed my issue. Now I have spaCy installed.
I had this same problem. A solution for updating setuptools
pip install -U setuptools
or
pip install setuptools --upgrade
Make sure that you've installed these required packages. It worked perfectly in my case as I installed the checked packages:
To expand on the answers by ocean800, davidsheldon and user3661384:
You should now no longer use Visual Studio Tools 2015 since a newer version is available. As indicated by the Python documentation, you should be using Visual Studio Tools 2017 instead.
Visual C++ Build Tools 2015 was upgraded by Microsoft to Build Tools for Visual Studio 2017.
Download it from here.
You will also require setuptools. If you don't have setup tools, run:
pip install setuptools
Or if you already have it, be sure to upgrade it.
pip install setuptools --upgrade
For the Python documentation link above you will see that setuptools version must be at least 34.4.0 for Visual Studio Tools to work.
Use the link to Visual C++ 2015 Build Tools. That will install Visual C++ 14.0 without installing Visual Studio.
I had the same issue. Downloading the Build Tools for Visual Studio 2017 worked for me.
I had exactly the same issue and solved it by installing mysql-connector-python with:
pip install mysql-connector-python
I am on Python 3.7 and Windows 10 and installing Microsoft Build Tools for Visual Studio 2017 (as described here) did not solve my problem that was identical to yours.
Just go to https://www.lfd.uci.edu/~gohlke/pythonlibs/ find your suitable package (whl file). Download it. Go to the download folder in cmd or typing 'cmd' on the address bar of the folder. Run the command :
pip install mysqlclient-1.4.6-cp38-cp38-win32.whl
(Type the file name correctly. I have given an example only). Your problem will be solved without installing build toll cpp of 6GB size.
To add on top of Sushant Chaudhary's answer:
In my case, I got another error regarding lxml as below:
copying src\lxml\isoschematron\resources\xsl\iso-schematron-xslt1\readme.txt -> build\lib.win-amd64-3.7\lxml\isoschematron\resources\xsl\iso-schematron-xslt1
running build_ext
building 'lxml.etree' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
I had to install lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl the same way as in the answer of Sushant Chaudhary to successfully complete installation of Scrapy.
Download lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl from Lxml
put it in folder where Python is installed
install it using pip install <file-name>
Now you can run pip install scrapy.
I had the same exact issue on my windows 10 python version 3.8.
In my case, I needed to install mysqlclient were the error occurred Microsoft Visual C++ 14.0 is required. Because installing visual studio and it's packages could be a tedious process, Here's what I did:
step 1 - Go to unofficial python binaries from any browser and open its website.
step 2 - press ctrl+F and type whatever you want. In my case it was mysqlclient.
step 3 - Go into it and choose according to your python version and windows system. In my case it was mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and download it.
step 4 - open command prompt and specify the path where you downloaded your file. In my case it was C:\Users\user\Downloads
step 5 - type pip install .\mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and press enter.
Thus it was installed successfully, after which I went my project terminal re-entered the required command. This solved my problem
Note that, while working on the project in pycharm, I also tried installing mysql-client from the project interpreter. But mysql-client and mysqlclient are different things. I have no idea why and it did not work.
I had a similar situation installing pymssql.
pip was trying to build the package, because there were no official wheels for Python 3.6 and Windows.
I solved it by downloading an unofficial wheel from Unofficial Windows Binaries for Python Extension Packages.
Specifically for your case: MySQL-python
I just had the same issue while using the latest Python 3.6. With Windows OS 10 Home Edition and a 64-bit operating system.
Steps to solve this issue:
Uninstall any versions of Visual Studio you have had, through Control Panel
Install Visual Studio 2015 and chose the default option that will install
Visual C++ 14.0 on its own
You can use PyCharm for installing Scrapy: Menu Project → Project Interpreter → + (install Scrapy)
Check Scrapy in the REPL and PyCharm by import. You should not see any errors.
None of the solutions here and elsewhere worked for me. It turns out an incompatible 32-bit version of mysqlclient is being installed on my 64-bit Windows 10 OS because I'm using a 32-bit version of Python.
I had to uninstall my current Python 3.7 32 bit, and reinstalled Python 3.7 64 bit and everything is working fine now.
If Visual Studio is NOT your thing, and instead you are using VS Code, then this link will guide you thru the installer to get C++ running on your Windows.
You only needs to complete the Pre-Requisites part.
https://code.visualstudio.com/docs/cpp/config-msvc/#_prerequisites
This is similar with other answers, but this link will probably age better than some of the responses here.
PS: don't forget to run pip install --upgrade setuptools
This works for me:
pip install --only-binary :all: mysqlclient
I tried ALL of the above and none worked. Just before before signing up for the booby hatch, I found another reason for the error : using the wrong shell on Windows.
conda init cmd.exe
did the trick for me. Hope it may save someone else, too.
I was facing the same problem. The following worked for me:
Download the unofficial binaries file from Christoph Gohlke installers site as per the Python version installed on your system.
Navigate to the folder where you have installed the file and run
pip install filename
For me python_ldap‑3.0.0‑cp35‑cp35m‑win_amd64.whl worked as my machine is 64 bit and Python version is 3.5.
This successfully installed python-ldap on my Windows machine. You can try the same for mysql-python.
Look if the package has an official fork that include the necessary binary wheels.
I needed the package python-Levenshtein, had this error, and found the package python-Levenshtein-wheels instead.
I had the same problem. I needed a 64-bit version of Python so I installed 3.5.0 (the most recent as of writing this). After switching to 3.4.3 all of my module installations worked.
Python Releases for Windows
I had the same issue while installing mysqlclient for the Django project.
In my case, it's the system architecture mismatch causing the issue. I have Windows 7 64bit version on my system. But, I had installed Python 3.7.2 32 bit version by mistake.
So, I re-installed Python interpreter (64bit) and ran the command
pip install mysqlclient
I hope this would work with other Python packages as well.
TLDR run vcvars64.bat
After endlessly searching through similar questions with none of the solutions working.
-Adding endless folders to my path and removing them. uninstalling and reinstalling visual studio commmunity and build tools.
and step by step attempting to debug I finally found a solution that worked for me.
(background notes if anyone is in a similar situation)
I recently reset my main computer and after reinstalling the newest version of python (Python3.9) libraries I used to install with no troubles (main example pip install opencv-python) gave
cl
is not a full path and was not found in the PATH.
after adding cl to the path from
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\Hostx64\x64
and several different windows kits one at a time getting the following.
The C compiler
"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.27.29110/bin/Hostx64/x64/cl.exe"
is not able to compile a simple test program.
with various link errors or " Run Build Command(s):jom /nologo cmTC_7c75e\fast && The system cannot find the file specified"
upgrading setuptools and wheel from both a regular command line and an admin one did nothing as well as trying to manually download a wheel or trying to install with --only-binary :all:
Finally the end result that worked for me was running the correct vcvars.bat for my python installation namely running
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat" once (not vcvarsall or vcvars32) (because my python installed was 64 bit) and then running the regular command pip install opencv-python worked.
I want to install MySqlclient on my windows system. I am Currently using Python 3.6. After going through the various post over Stackoverflow, I could Not find the correct way.
This is what I have done so far:
1) Installation by using pip pip install mysqlclient. Error:
Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools" http://landinghub.visualstudio.com/visual-cpp-build-tools
I already have Microsoft Visual C++ installed on my laptop. Some are saying you need 2015 edition.
2) Installation by using wheel file pip install mysqlclient-1.3.13-cp36-cp36m-win_amd64.whl. Error:
Requirement mysqlclient-1.3.13-cp36-cp36m-win_amd64.whl looks like a filename, but the file does not exist.
mysqlclient-1.3.13-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.
2.1) Changing the whl file to different version pip install mysqlclient-1.3.13-cp36-cp36m-win32.whl. Error:
Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'C:\\Users\\Foxtrot\\Desktop\\finaltest\\mysqlclient-1.3.13-cp36-cp36m-win32.whl'
Other things that are done: updated setuptools, updated wheel.
Had the same problem, searched the web etc. Here this answer:
mysql-python install error: Cannot open include file 'config-win.h'
It has all the instructions. In short go to this site: https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient:
At that website you will find
mysqlclient‑1.3.13‑cp36‑cp36m‑win32.whl
mysqlclient‑1.3.13‑cp36‑cp36m‑win_amd64.whl
Download the correct file for your platform.
Then use your downloaded wheels file with pip and you're done:
pip install c:\mysqlclient‑1.3.13‑cp36‑cp36m‑win_amd64.whl
The https://www.lfd.uci.edu/~gohlke/pythonlibs has lots of lots of compiled libraries to solve the problem of building them from source yourself. They even compile them for python 3.7 :)
Alternative Solution
You can also download Visual C++ Build Tools and then you should be able to install every (at least to my knowledge) version of mysqlclient with pip.
To do this go to this site: https://www.scivision.co/python-windows-visual-c++-14-required/ there you can find out which version of Build Tools you need and you can also find a link to download the installer. Be aware though Build Tools require more than 4GB of free disk space.
Tell pip not to use sources and use binary packages instead:
pip install --only-binary :all: mysqlclient
https://pip.pypa.io/en/stable/reference/pip_install/#install-only-binary
I can't find mysqlclient-1.3.13's whl file on PyPi. So you need to compile it from source. Unfortunately it's not easy. I'm not Windows guy, so I only can recommend guide like this
I am using python3.7 on Windows 10 operating system.
I had same issue and after a long research I had installed it successfully.
Install "Microsoft Visual C++ Build Tools"
AND
My OS is having 64 bit operating system but still then it need to install 32 bit version
"mysqlclient‑1.4.2‑cp37‑cp37m‑win32.whl"
Download binary wheels from "https://www.lfd.uci.edu/~gohlke/pythonlibs/" and run command
pip install [path_to_downloaded_file] eg: C:\Users\Ds\mysqlclient-1.4.2-cp37-cp37m-win32.whl
use pipenv instead of pip if you are using virtual environment.
The error means that the package has not yet been compiled for your versions of OS and Python. So pip tries to build it from the source for you.
There are two possible solutions.
The first option is to install the most recent version of Microsoft Visual C++ Build Tools. Just go ahead and download it from the Microsoft website. Then pip should be able to compile the package.
Another option is using an unofficial binary. As mentioned here, a resource proved to be useful is https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python . Just download the pre-compiled package and install it using
pip install c:\path-to-a-pre-compiled-package
Had the same problem just day.
Tried to install mysqlclient on a Windows Server R2.
[...]
Tl;dr
"MySQL Connector C 6.1" was installed in the wrong directory: "C:\Program Files\MySQL" instead of "C:\Program Files (x86)\MySQL" where it should be for me.
--> Copied "MySQL Connector C 6.1" to "C:\Program Files (x86)\MySQL" Directory.
"C:\Users\MoBoo\AppData\Local\Temp" was Read-Only: Therefore pip couldn't compile files into Temp dir.
--> Allow Write access to "C:\Users\MoBoo\AppData\Local\Temp" Directory.
Here is what worked for me. I uninstalled mysql and re-installed it.
pip uninstall mysqlclient
Then simply re-install, so it picked the current version "1.4.2.post1"
pip install mysqlclient
Which interestingly, works straightaway.
for this error, most of user's suggest to install vs build but there is an alternative which works perfectly in my case and is sure for you too.
Download latest MySQL client from here
mysqlclients
Here you can see many version but prefer to download the latest one which has 32 bit and 64-bit files.
download theme and past the file on your projects root folder then run the same command but with the full file name of downloaded mysqlclient.
like: pip install mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl
in my case, the file is this
also if have already the XAMPP server then you can use its PHPMyAdmin with python.
You just need to change on your roots setting.py file for this.
Something like this
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'mydjango',
'USER': 'root',
'PASSWORD':'',
'HOST':'localhost',
'PORT':'3306',
}
}
The port is the same which you see on xampp panel just before the start button of MySQL.
After changing this you just again start your server by hitting this command
python manage.py runserver
If you didn't see any error then congratulations you successfully connected with MySQL database.
Enjoy...
The easiest way to solve this problem is to download the correct version of MySQL client that supports the python version installed on your system.
MYSQLclient download link: https://pypi.org/project/mysqlclient/#files
Check the python version installed in your PC:
I was using Python version 3.7 and the same error was happening.
After trying all the possibilities, simply reinstalling the newest Python version (3.10.7 in my case) solved the issue.
I am trying to install dedupe module and I am getting an error below,
error: command 'cl.exe' failed: No such file or directory
Failed building wheel for dedupe
Failed building wheel for dedupe-hcluster
Failed building wheel for affinegap
Failed building wheel for pylbfgs
Failed building wheel for pyhacrf-datamade
I found this link, that did not help me to resolve.
I am using Windows 10 , 64-bit, Python 3.5.4 :: Anaconda custom (64-bit).
I found the .whl file here, (dedupe-1.9.2-cp35-cp35m-manylinux1_x86_64.whl) downloaded it and tried to use pip install <>.whl and I got an error,
dedupe-1.9.2-cp35-cp35m-manylinux1_x86_64.whl is not a supported wheel
on this platform.
Any ideas on how to resolve this issue?
So, finally, after more research I successfully installed dedupe library. Just thought of posting my own answer if anyone might come across this issue.
In the beginning I only had Visual Studio Build Tools 2017 installed with Visual Studio 2015.
After posting the question I installed Visual Studio Community 2017 (2). And then tried use pip install dedupe still gave me errors like in this post.
Then according to the post, I upgraded the numpy =1.14 and tried pip install dedupe, it worked.
(I am not an expert python setup person, not sure how to explain other than this plain explanation)
I downgraded my python version and it worked first try
