“Check if curl is installed” is a common question among web developers, API testers, and server administrators. Curl is a powerful command-line tool that allows users to send HTTP requests and receive responses from servers. However, before you can start using curl, you need to make sure it’s installed on your system. In this guide, we’ll show you how to check if curl is installed on your Windows, macOS, or Linux machine, troubleshoot common installation issues, and even install curl if it’s not already on your system.

- You can view curl’s version number and other details if it is installed. If not, errors will appear.
You can quickly determine whether curl is installed on your system by adhering to these straightforward steps. If you run into any problems, move on to the next section to troubleshoot typical installation problems.
Troubleshooting Curl Installation Issues
One of the following problems could be to blame if you run into an error message when attempting to check that curl is installed:
- Your system doesn’t have curl installed.
- Your system’s PATH environment variable does not contain curl.
- Although installed, curl is not set up properly.
Follow these steps to troubleshoot these problems:
- By running “curl –version`” in your terminal, you can verify the installation of curl on your system. You can download the most recent version from the official website if curl is not installed.
- You can add curl by following these steps if it is installed but not in the PATH environment variable on your system:
– Windows: navigate to Control Panel, System and Security, System > Environment Variables and advanced system settings are listed. Find the “Path” variable under System Variables and select “Edit.” Add the path directory where curl is installed to the list.
– macOS and Linux: Launch your terminal and edit the “~/.bashrc” or “~//.bash_profile” file by adding the following line: “export PATH=$PATH:/path/to/curl/directory`. The actual path to the directory where curl is installed should be replaced by the “/path/to/curl/directory.” - You might need to reinstall curl if it is installed but not configured properly. To do this, adhere to these steps:
- Launch the most recent version of curl from the official website.
- In a directory of your choice, extract the downloaded file.
- Add the directory to the PATH environment variable on your system.
- If curl is installed, test by running “curl –version`” in your terminal.
Common Errors Messages
When using curl or installing it, you might run into some typical errors:
- This error message states that curl is not installed on your system or is not located in the PATH environment variable in your system. To install or add curl to your PATH, adhere to the above instructions.
- Curl: (7) failed to connect to [URL] Connection refused: This error message indicates that curl was unable to access the desired URL. Verify the URL on your internet connection to confirm that it is accurate.
- “curl: (60) SSL certificate issue: unable to get local issuer certificate”: This error message indicates that curl was unable to verify the SSL certificate of the server you’re connecting to. By including the “-k” or “–insecure” option in your curl command, you can avoid this error, but security precautions are not taken.
Make sure you have the appropriate version of curl on your system if you’re having trouble installing it on Windows. There are distinct versions for 64-bit and 32-bit systems, and using the incorrect version can lead to installation problems.
Installing Curl
Installing curl on your system is the first step in using it. The installation of curl on Windows, macOS, and Linux will be demonstrated in this section.
Windows is a good example.

- Open Command Prompt and navigate to the location where you extracted curl.
- Press Enter after typeing the following command:
"Setx path "%path%;C:\path\to\curl"
You can run curl from any directory in Command Prompt using this command, which also adds the path to the curl executable to the PATH environment variable on your system.
5. If curl is installed, test by using the following command in your terminal:
curl,version
Using PowerShell, you can apply the phrase “###
Follow these instructions to install curl on Windows using PowerShell:
- The official website offers the most recent version of curl.
- In a directory of your choice, extract the downloaded file.
- The directory where you extracted curl can be opened by using PowerShell.

Curl Alternatives
Although curl is a strong tool, there are other, more useful tools you can use for particular things. The following are some curl substitutes:
wget ### wget
A command-line tool called “wget” is used to download websites’ files. It can be used to download entire websites or particular files and supports the HTTP, HTTPS, and FTP protocols. The ability to resume interrupted downloads is one benefit of wget
over curl.
www.websites.com.
A command-line tool for handling HTTP requests with a more user-friendly interface is called ‘httpie’. It can be used to test APIs and supports JSON, form data, and file uploads. The ability of httpie
to display response headers in a more readable format is one benefit of curl over co.
The Postman is a member of the media.
A tool for testing APIs with a graphical user interface is called “Postman”. Users can make and save requests, organize them into collections, and share them with others using it. The ability to save and reuse requests makes it simpler to test APIs with complex authentication or authorization requirements, which is one benefit of `Postman’.
These alternatives might not have all the features of curl, but they can be useful for particular tasks and workflows. It’s important to look into these tools to see if they can enhance your administration or development workflow.
