When you encounter the error message "request to https registry npmjs org webpack failed reason unable to get local issuer certificate," it can be a frustrating experience. This error message typically shows up when you are trying to install a package through NPM and indicates that the SSL certificate – which is used to ensure a secure connection – is not valid or cannot be verified by the registry. Here is what you need to know to troubleshoot this error and get your project up and running.
What Causes the "Unable to Get Local Issuer Certificate" Error?
Before we get into the specifics of how to fix the error, it's essential to understand what causes this error message to show up.
There are a few reasons why you might receive the "unable to get local issuer certificate" error. Some of the most common reasons are:
The SSL certificate is not valid: Sometimes, the SSL certificate used by the registry, in this case npmjs.org or webpack, is not valid or has expired. If the SSL certificate is invalid, your computer won't be able to verify the authenticity of the website or package you are trying to install.
The SSL certificate is not trusted: Even if the SSL certificate is valid, your computer may not trust it, which can cause the "unable to get local issuer certificate" error to appear. If your computer is running an outdated operating system or web browser or has customized security settings, it may not trust the SSL certificate.
The root certificate is missing: A missing root certificate is another potential cause of the "unable to get local issuer certificate" error. The root certificate is used to verify the validity of SSL certificates from websites and other sources.
How to Fix the "Unable to Get Local Issuer Certificate" Error
There are several ways to fix the "unable to get local issuer certificate" error. Here are some of the most straightforward solutions you can try:
Solution 1: Update Your Operating System and Web Browser
If your computer's operating system or web browser is outdated, it may not trust the SSL certificate used by the registry. Updating your operating system and web browser can fix this problem. It's also a good practice to keep your software up-to-date for better security.
Solution 2: Update Your Certificate Store
Updating your computer's certificate store manually can also fix the "unable to get local issuer certificate" error. Here is how to do that:
Open your web browser and access the registry URL (npmjs.org or webpack) in question.
Click on the padlock symbol next to the URL, and then click on "Certificate."
On the certificate window, click on the "Details" tab, then click on "Copy to File."
In the Certificate Export Wizard, click "Next," select "DER encoded binary X.509 (.cer)," and click "Next" again.
Choose a location to save the certificate file, and then click "Next" and "Finish."
Finally, open the Windows Command Prompt as an administrator and enter the following command:
certutil -addstore root example.crt
Note: replace 'example.crt' with the name of the certificate file you just saved.
Solution 3: Configure npm to Use HTTP instead of HTTPS
If you can install the package using HTTP instead of HTTPS, you can configure npm to use HTTP. Here is how to do that:
- Open your Terminal or Command Prompt and type the following command:
npm config set registry http://registry.npmjs.org/
Press "Enter" to execute the command.
Start the package installation process again, but this time, use HTTP instead of HTTPS.
Solution 4: Use a Trusted SSL Certificate
If you are a package developer, installing a trusted SSL certificate on your server can fix the "unable to get local issuer certificate" error. A trusted SSL certificate is one that is issued by a trusted certificate authority, such as Comodo, Symantec, or DigiCert.
Solution 5: Contact Your IT Administrator for Assistance
If you are still experiencing the "unable to get local issuer certificate" error, you may need to contact your IT administrator for assistance. They should be able to help resolve this problem, especially if the error message is caused by customized security settings or firewalls.
In summary, the "unable to get local issuer certificate" error can be frustrating, but it does not have to halt your project progress.

I can provide more information on the previous topics. Let's start with the SSL certificate.
SSL (Secure Sockets Layer) is a security technology that is used to establish a secure and encrypted connection between a web server and a web browser. The SSL certificate is a digital certificate that is used to verify the identity of the website owner and encrypts sensitive data that is transmitted over the Internet.
When a website is secured with an SSL certificate, the URL starts with "https" instead of "http." This indicates that the website is using a secure connection and that any information that is transmitted between the web server and web browser is encrypted.
There are different types of SSL certificates, including Domain Validated (DV), Organization Validated (OV), and Extended Validation (EV) certificates. These certificates differ in the level of validation that is required before the certificate is issued, with EV certificates offering the highest level of validation.
SSL certificates are issued by Certificate Authorities (CAs), which are trusted third parties that validate the identity of the certificate holder. Some of the most popular CAs include Comodo, Symantec, DigiCert, and GlobalSign.
Updating Software and Security Settings
Keeping your software and security settings up-to-date is essential for maintaining a secure and stable system. Outdated software can contain vulnerabilities that can be exploited by hackers, while customized security settings can interfere with the proper functioning of web applications and services.
To avoid the errors caused by outdated software or security settings, it is recommended to regularly update your system software and web browser. You should also review your security settings periodically and adjust them as necessary to allow for the proper functioning of web applications and services.
Finally, if you are having trouble installing a package through NPM or encountering other errors, it is essential to seek help from the appropriate channels. You can consult the NPM website's documentation, seek help from the NPM community, or contact your IT administrator for assistance.
In conclusion, resolving errors such as the "unable to get local issuer certificate" error requires understanding the causes of the error and taking appropriate remedial action. By keeping your software and security settings up-to-date and seeking help as needed, you can ensure the uninterrupted functioning of your web applications and services.
