Solving problem is about exposing yourself to as many situations as possible like Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat) and practice these strategies over and over. With time, it becomes second nature and a natural way you approach any problems in general. Big or small, always start with a plan, use other strategies mentioned here till you are confident and ready to code the solution.
In this post, my aim is to share an overview the topic about Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat), which can be followed any time. Take easy to follow this discuss.
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 FilesPython 3.5Scripts;
C:Program FilesPython 3.5;
C:WindowsSystem32;
C:Program Files (x86)Microsoft Visual Studio 12.0VC;
C:Program Files (x86)Microsoft Visual Studio 11.0VC
I have a 64bit win 7 setup in my PC.
What could be the solution for mitigating this error and installing the modules correctly via pip
.
Answer #1:
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
Edit: New working link
Edit: As suggested by Lightfire228, you may also need to upgrade setuptools
package for the error to disappear:
pip install --upgrade setuptools
Answer #2:
Binary install it the simple way!
I can’t believe no one has suggested this already – 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.
Answer #3:
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:
-
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 3 choices. Only check Desktop development with C++
b. Under Web & Cloud, there are 7 choices. Only check Python development (I believe this is optional But I have done it).
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 3 ones 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 dont need to install Visual Studio Community Edition itself) => This minimal install is already a 4.5GB, so saving off anything is helpful
Answer #4:
As the other responses pointed 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 http://www.lfd.uci.edu/~gohlke/pythonlibs (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
.
Answer #5:
I had the exact issue while trying to install 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 in 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 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 softwares/packages/etc.?
Answer #6:
After reading a lot of answers in SO and none of them working, I finally managed to solve it following the steps in this thread, I will leave here the steps in case the page dissapears:
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.
Hope it helps as it did for me.
Answer #7:
I had this exact issue while trying to install mayavi
.
So 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 thread, with none of them working. I figured 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 underAll 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 installed many of them).- If you have already installed
Build Tools for Visual Studio 2017
then open the applicationVisual Studio Installer
then go toVisual 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
.
- If you have already installed
-
Install/Modify these components for
Visual Studio Build Tools 2017
. -
This is the important step. Open the application
Visual Studio Installer
then go toVisual Studio Build Tools
>>Launch
. Which will open a CMD window at the correct location forMicrosoft Visual StudioYYYYBuildTools
.
- 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>
.
Answer #8:
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 following platform and versions:
Python 3.6 on Windows 7 64-bit
Python 3.8 on Windows 10 64-bit
I have same suggestion as a comment to the question, however, I have been requested to post this as an answer as it helped a lot of people. So I posted it as an answer.
