Failed to load the TSLint library for the document in Visual Studio Code

I have installed the latest versions of Visual Studio Code, Node.js, and Typescript on my Windows 10 machine. However, when I try to use TSLint in the terminal, I get the following error message:

Failed to load the TSLint library for the document...

I tried reinstalling TSLint, but I got the following error message:

npm install -g tslint

And got the following message:

npm WARN [email protected] requires a peer of typescript@>=2.1.0 || >=2.1.0-dev || >=2.2.0-dev || >=2.3.0-dev || >=2.4.0-dev || >=2.5.0-dev || >=2.6.0-dev || >=2.7.0-dev || >=2.8.0-dev || >=2.9.0-dev but none is installed. You must install peer dependencies yourself.

You must install peer dependencies yourself.

Restarting Visual Studio Code did not help, and I am still getting the error message that TSLint cannot be loaded.

How can I fix this issue and use TSLint in Visual Studio Code?

tsutils and typescript are "peer" dependencies of TSLint, meaning TSLint requires that they be installed but won't do it for you _(this helps make sure TSLint uses the dependency versions you have, rather than providing confusingly different versions on its own). Try:

npm i tsutils typescript

...to install them manually.

Isn't that error message informing you about the missing extension? It bundles its own version of TSLint.

Try installing the vscode-tslint extension.
