The SDK directory for TypeScript 1.3 in Visual Studio 2013 does not include the necessary tsc.exe file

Exciting news! Typescript v1.3 has been officially announced today. To fully utilize this update, I quickly installed the power tools update for VS2013.

Upon completion of the installation, my Visual Studio environment now recognizes the "protected" keyword and tuple types. This new feature is definitely a welcomed addition!

However, when I decided to upgrade the TypeScriptToolsVersion attribute in my *.csproj file from 1.1 to 1.3:

<TypeScriptToolsVersion>1.3</TypeScriptToolsVersion>

An error occurred during the build process:

The specified task executable location "C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.3\tsc.exe" is invalid.

It appears that the "1.3" folder was not automatically generated by the installer.

To resolve this issue, I resorted to simply duplicating the existing 1.1 compiler.

Does anyone have insights into why the 1.3 folder was omitted from this release?

Note: Utilizing VS Professional 2013 (12.0.30723.00 Update 3)

Answer №1

The latest version 1.3 will now be installed in the 1.1 folder, and new projects will automatically set the <TypeScriptToolsVersion> property in the project file to "1.1" as well. This element value is crucial as it determines where to find the compiler at "C:\Program Files (x86)\Microsoft SDKs\TypeScript". It's important for this value to stay synchronized.

Multiple compiler versions can coexist side by side, like we've seen with the 1.0 and 1.1 folders. The compiler corresponding to the TypeScriptToolsVersion setting in the project will be used for building the project. We don't update the targeted version automatically to ensure compatibility with other users who may not be using the latest toolsets.

However, only one version of the language service can exist in Visual Studio, which will always be the most recent installation. Despite this, older project versions should still function correctly due to our commitment to maintaining backwards compatibility. Any new features incompatible with the specified compiler version will result in compile-time errors but won't affect your ability to edit the project.

If you open a project with an earlier version specified, a warning will alert you that the project version doesn't match the language service. This warning is harmless and simply advises you that some new features might cause problems during compilation. Adding unsupported language service features will trigger build errors, as warned by the initial notification.

We understand this system isn't perfect and are actively exploring ways to improve it. We apologize for any confusion it may have caused.

Answer №2

After recently updating the tsUnit project to TypeScript 1.3, I noticed that the tools version had changed:

<TypeScriptToolsVersion>1.0</TypeScriptToolsVersion>

The new tools version was:

<TypeScriptToolsVersion>1.1</TypeScriptToolsVersion>

This discrepancy means that the "Tools Version" does not align with the language version.

  • TypeScript 1.1 has ToolsVersion 1.0
  • TypeScript 1.3 has ToolsVersion 1.1

It's important to recognize that the language, compiler, and tools can have varying versions. To check the language version, run tsc -v which should display Version 1.3.0.0 for the latest version (as of November 2014).

Answer №3

Why was the exclusion of the 1.3 folder not addressed in this particular release?

This insightful response sheds light on the matter: https://github.com/Microsoft/TypeScript/issues/1138#issuecomment-62993605 Quote:

For those wondering, you should find the 1.3 language services within tools version 1.1, while the 1.1 folder should house the 1.3 compiler. It's admittedly a bit confusing.
