How to install "gatsby-plugin-sharp" plugin

Question

When I run the command gatsby develop to start development server, I get the following error message:

success open and validate gatsby-configs — 0.006 s error UNHANDLED REJECTION

Error: Unable to find plugin "gatsby-plugin-sharp". Perhaps you need to install its package?

And when I try to install it, it shows following message:

 npm install --save gatsby-plugin-sharp

I have already searched for this error from git site but the issue came out the same. Please help me resolve this issue.

Answer 1

Did you npm install all the dependencies for your project? If you don't use gatsby-plugin-sharp , you could remove it from the gatsby-config.js and see if your app is running without it.

Something seems to be wrong with your Python environment: Error: Can't find Python executable "python", you can set the PYTHON env variable. Do you get this error when npm install ing other packages?

Answer 2

Did you install C++ tools : Visual Studio Community 2015 or 2017 Package and npm config set msvs_version 2015

npm install --global --production windows-build-tools

The tool does not seem compatible with python 3 You can force the use of Python 2 after installing it npm config set python python2.7 or

node-gyp install --python C:\\Python27
