Error[package-solution] No manifests were found in 'C:\Users\cloud\LP\Widget\ModernPnP\search-parts/dist'. Ensure a build has completed successfully

As we continue to migrate our SPFx web part to version 1.19.0, we encounter an error that prevents us from successfully packaging our solution. The error message reads: "Error[package-solution] No manifests were found in 'C:\Users\cloud\LP\Widget\ModernPnP\search-parts/dist'. Ensure a build has completed successfully." In this article, we will delve into the possible causes of this error and provide a step-by-step guide to resolve it.

The error message suggests that the gulp package-solution command is unable to find any manifests in the dist folder. This folder is where the bundled and minified files are stored after a successful build. The gulp package-solution command is responsible for creating a package file that can be uploaded to the SharePoint tenant.

Before we dive into the solution, let's explore the possible causes of this error:

  • Incomplete Build: The error message suggests that the build has not completed successfully. This could be due to a variety of reasons such as missing dependencies, incorrect configuration, or errors in the code.
  • Missing Manifests: The gulp package-solution command relies on the presence of manifests in the dist folder. If these manifests are missing, the command will fail.
  • Incorrect Configuration: The configuration files such as config.json and package-solution.json play a crucial role in the packaging process. Any errors or inconsistencies in these files can cause the error.

To resolve the error, follow these steps:

Step 1: Verify the Build

Before attempting to package the solution, verify that the build has completed successfully. Run the following command:

gulp build --ship

This command will build the solution and create the necessary files in the dist folder.

Step 2: Check the Manifests

Verify that the manifests are present in the dist folder. The manifests should be in the following format:

{
  "name": "Widget",
  "version": "1.0.0",
  "description": "A widget for SharePoint",
  "main": "widget.js",
  "scripts": {
    "start": "gulp start"
  },
  "dependencies": {
    "@microsoft/sp-core-library": "^1.1.1",
    "@microsoft/sp-lodash-subset": "^1.1.1"
  },
  "devDependencies": {
    "@microsoft/gulp-core-build": "^1.0.0",
    "@microsoft/sp-build-web": "^1.1.1"
  }
}

Step 3: Check the Configuration Files

Verify that the configuration files such as config.json and package-solution.json are correct and up-to-date. The config.json file should contain the following information:

{
  "version": "1.0.0",
  "name": "Widget",
  "description": "A widget for SharePoint",
  "main": "widget.js",
  "scripts": {
    "start": "gulp start"
  },
  "dependencies": {
    "@microsoft/sp-core-library": "^1.1.1",
    "@microsoft/sp-lodash-subset": "^1.1.1"
  },
  "devDependencies": {
    "@microsoft/gulp-core-build": "^1.0.0",
    "@microsoft/sp-build-web": "^1.1.1"
  }
}

The package-solution.json file should contain the following information:

{
  "name": "Widget",
  "version": "1.0.0",
  "description": "A widget for SharePoint",
  "main": "widget.js",
  "scripts": {
    "start": "gulp start"
  },
  "dependencies": {
    "@microsoft/sp-core-library": "^1.1.1",
    "@microsoft/sp-lodash-subset": "^1.1.1"
  },
  "devDependencies": {
    "@microsoft/gulp-core-build": "^1.0.0",
    "@microsoft/sp-build-web": "^1.1.1"
  }
}

Step 4: Run the Package-Solution Command

Once you have verified that the build has completed successfully and the manifests are present, run the following command:

gulp package-solution --ship

This command will create a package file that can be uploaded to the SharePoint tenant.

In this article, we have explored the possible causes of the error "Error[package-solution] No manifests were found in 'C:\Users\cloud\LP\Widget\ModernPnP\search-parts/dist'. Ensure a build has completed successfully." and provided a step-by-step guide to resolve it. By following these steps, you should be able to successfully package your SPFx web part and upload it to the SharePoint tenant.

If you continue to encounter issues, try the following troubleshooting tips:

  • Check the console output: Verify that there are no errors or warnings in the console output.
  • Check the configuration files: Verify that the configuration files are correct and up-to-date.
  • Check the manifests: Verify that the manifests are present in the dist folder.
  • Try a clean build: Run the following command to perform a clean build:
gulp clean
gulp build --ship
gulp package-solution --ship

This will remove any temporary files and perform a fresh build.
