tsc command not found TypeScript error [Solved]

If you’ve encountered the error “tsc: command not found” while working with TypeScript, there are a few different approaches you can try to resolve it. Here are a few different solutions you can try:

Solution 1: Use the npx Command with the –package Flag

One quick way to solve the error is to use the ‘npx’ command with the –package flag. This will allow you to run the ‘tsc’ command without having to install the TypeScript package globally.

Here’s an example of how you can use the ‘npx’ command to initialize a tsconfig.json file and check the version of the TypeScript package:

npx --package typescript tsc --initnpx --package typescript tsc --version

Note that we used the –package flag to specify the correct TypeScript package in the commands above.

Solution 2: Install TypeScript Globally

Alternatively, you can install the TypeScript package globally by running the following command:

npm install typescript@latest -gtsc --inittsc --version

This will allow you to use the ‘tsc’ command without having to prefix it with ‘npx’ and use the –package flag.

If the global installation of TypeScript fails, you may need to run the command prefixed with ‘sudo’:

sudo npm install typescript@latest -gtsc --inittsc --version

Solution 3: Update Your PATH Environment Variable

If neither of the above solutions work, you may need to update your PATH environment variable to include the path where ‘npm’ puts your globally installed packages. To do this, you can run the following command:

npm config get prefix

This will output the path where global packages are stored. You’ll want to add this path to your PATH environment variable.

On macOS, you can update your PATH with the following command:

export PATH=/usr/local/share/npm/bin:$PATH

On Windows, the output of the npm config get prefix command will look something like C:\Users\Your_User_Name\AppData\Roaming\npm. You’ll want to add this path to your PATH environment variable.

On Linux, you can add the output from the npm config get prefix command to your .bashrc file:

export PATH="/usr/local/share/npm/bin:$PATH"

Remember to restart any open command prompts after updating your PATH environment variable.

Solution 4: Reinstall Node.js

If none of the above solutions work, you may need to try reinstalling Node.js on your machine. Once Node.js is reinstalled, you can then install the TypeScript package globally by running “npm install typescript@latest -g”.

During the installation process, you may be prompted to update the PATH environment variable on your system. Make sure to select this option if it is offered.

If the global installation of TypeScript fails, you may need to run the command prefixed with ‘sudo’. For example:

sudo npm install typescript@latest -g

Alternatively, you can see how to fix the permissions error on this page in the official npm documentation.

Conclusion

To solve the error “tsc: command not found“, try one of the following solutions:

• Use the ‘npx’ command with the –package flag.
• Install the TypeScript package globally using ‘npm install typescript@latest -g’.
• Update your PATH environment variable to include the path where npm stores global packages.
• If none of the above solutions work, try reinstalling Node.js and then installing the TypeScript package globally using “npm install typescript@latest -g”.

I hope one of these solutions helps you resolve the “tsc: command not found” error and allows you to continue working with TypeScript. If you have any questions or need further assistance, don’t hesitate to ask.
