Как исправить ошибку executable not found

Nobody likes errors, least of all computer programmers!

If you are a PHP developer and recently installed Visual Studio Code (VS Code), then you are most likely getting a pesky «PHP executable not found» error message every time you start the program.

Some other VS Code error message you will see with the PHP executable not found message includes:

• Install PHP 7 and add to your PATH»
• «set php.executablePath setting»
• «Cannot validate since no PHP executable is set»
• «Use the php.validate.executablePath to configure the PHP executable»

With every single one of these VS Code error messages, you simply need to update your Windows PATH setting for your PHP executable location. Doing that will fix all of these PHP executable errors!

How to fix PHP executable not found error in VS Code

• Install php on your computer (e.g. with XAMPP)
• Locate your php installation directory
• Open Advanced System Settings on Windows
• Update the Windows «PATH» environment variable
• Close VS Code and reopen it

Step 1: Install php on your computer (e.g. with XAMPP)

The first and very most important step to fix the PHP executable not found error on Visual Studio Code is to actually have PHP installed on your computer. Now that might seem like an obvious starting point, but you would be surprised how many people don’t have PHP installed on their local web dev environment (e.g. their localhost server).

Personally, I have always been a fan of the XAMPP suite by ApacheFriends.org. I have been using the XAMPP suite to install PHP, MySQL, and phpMyAdmin for my localhost web servers for years. I highly recommend.

Step 2: Locate your php installation directory

Once you have PHP installed on your local computer (as part of your localhost server), you need to find the PHP installation directory. As we need the folder path that holds your php.exe file.

If you installed XAMPP, simply browse to your XAMPP installation directory. The default location is at C:xampp. From inside the XAMPP folder, open the PHP folder and locate the php.exe file. If you can find the php.exe file from in this folder, then this folder will be your php installation directory.

Step 3: Open Advanced System Settings on Windows

Now that we know your php installation directory, we need to open the actually add the folder path into the Windows’ PATH. But to get there, you have to open a few different screens.

From the your file explorer or desktop, right click on «This PC». Then select «Properties» from the drop down. Doing this will open the Windows control panel menu for your system settings.

From the system settings menu, you will see all of your computer’s basic information like RAM, CPU size, and your computer name.

On the left hand side of the program, you will see an option to open «Advanced System Settings». Go ahead and open the Windows advanced system settings program.

Please note: this WILL require you to have administrative permissions on your Windows computer. If you do not, then you will have to contact the person that does in order to update the Windows PATH variable.

Step 4: Update the Windows «PATH» environment variable

Once you have successfully found and opened the Windows advanced system settings popup, you can edit your Windows environment variables. While selected to the Advanced tab in the popup, click on the «Environment variables…» button at the bottom. This will open another program.

From here you can update all of your Windows environment variables. But in order to fix the PHP executable not found error message in VS Code, we really only care about the PATH variable.

So, from the list of User variables, select the «Path» option. Then click the Edit button. This will open the variable editor window.

Inside of the variable editor window, you can create a new PATH variable quite easily. Simply click the «New» button on the right hand side. Then enter in your PHP installation directory that we got from the step above.

Be sure to click away from the new path you created to ensure the updated PHP path is correctly saved into Windows.

Step 5: Close VS Code and reopen it

When you have successfully saved your PHP path location into the Windows PATH variable, you can close out of all of the Windows control panel windows.

You can now close VS code and reopen it. And you will notice that you have gotten rid of the «PHP executable not found» error message that you get on VS code start up. Great success!

It’s common for developers to encounter the «Executable file not found in $PATH» error when running applications or using command line tools. In this guide, we’ll walk you through the troubleshooting process to resolve this issue quickly and effectively. We’ll also answer some frequently asked questions related to the error.

Understanding the $PATH variable

The $PATH variable is an environment variable that lists the directories where executable files and scripts are located. When you run a command, the shell searches for the corresponding executable file in the directories listed in the $PATH variable. If the file isn’t found in any of them, the «Executable file not found in $PATH» error occurs.

The $PATH variable is essential to the proper functioning of your system, as it allows you to run commands without specifying the full path to the executable file.

Step-by-step troubleshooting guide

Follow these steps to resolve the «Executable file not found in $PATH» error:

Step 1: Verify the command and file location

Before troubleshooting the $PATH variable, make sure you’re using the correct command and the file is located in the correct directory.

1. Double-check the command you’re using
2. Verify the location of the executable file
3. If necessary, move the file to the appropriate directory or adjust the command

Step 2: Check the $PATH variable

Inspect the $PATH variable to ensure it includes the directory containing the executable file. To view the current $PATH variable, use the following command:

For Linux and macOS:

echo $PATH

For Windows (Command Prompt):

echo %PATH%

For Windows (PowerShell):

echo $env:PATH

Ensure the directory containing the executable file is listed in the $PATH variable. If not, proceed to the next step.

Step 3: Modify the $PATH variable

Add the directory containing the executable file to the $PATH variable using the following commands:

For Linux and macOS:

export PATH=$PATH:/path/to/directory

For Windows (Command Prompt):

setx PATH "%PATH%;C:pathtodirectory"

For Windows (PowerShell):

$env:PATH += ";C:pathtodirectory"

Once you’ve added the directory to the $PATH variable, try running the command again. If the error persists, proceed to the next step.

Step 4: Make the file executable

Ensure the file has executable permissions by running the following command:

For Linux and macOS:

chmod +x /path/to/file

For Windows, right-click the file, select «Properties,» and check the «Read» and «Execute» permissions under the «Security» tab.

Try running the command again. If the error still occurs, double-check the previous steps and consult the application’s documentation for further guidance.

FAQs

Why does the «Executable file not found in $PATH» error occur?

This error occurs when the shell cannot find the specified executable file in the directories listed in the $PATH variable. It could be due to an incorrect command, the file not being in the expected directory, or the directory not being included in the $PATH variable.

How do I permanently add a directory to the $PATH variable?

To permanently add a directory to the $PATH variable, modify the appropriate configuration file for your shell. For example, add the export PATH=$PATH:/path/to/directory command to the .bashrc or .bash_profile file if you’re using Bash on Linux or macOS. For Windows, use the «Environment Variables» editor in the «System Properties» dialog.

Can I have multiple directories in the $PATH variable?

Yes, you can have multiple directories in the $PATH variable, separated by colons (:) on Linux and macOS or semicolons (;) on Windows.

Can I use relative paths in the $PATH variable?

It’s not recommended to use relative paths in the $PATH variable, as it can lead to unexpected behavior. Always use absolute paths to ensure the shell can find the executable files.

What’s the difference between the $PATH variable and the working directory?

The $PATH variable lists the directories where the shell searches for executable files, while the working directory is the current directory the shell is operating in. The working directory can be changed using the cd command, whereas the $PATH variable is typically modified through configuration files or environment variable editors.
