Self-help instructions#

To see the LSP server and client communication, run LSP: Toggle Log Panel from the Command Palette. Logs are useful to diagnose problems.


It might be a good idea to restart Sublime Text and reproduce the issue again so that the logs are clean.

If you believe the issue is with this package, please include the output from the Sublime console in your issue report!

If the server is crashing on startup, try running LSP: Troubleshoot server from the Command Palette and check the "Server output" for potential errors. Consider sharing the output of this command in the report.

Updating the PATH used by LSP servers#

Sublime Text might see a different PATH from what your shell environment uses and might not be able to find the server binary due to that. You can see what ST thinks your PATH is by opening the ST console by clicking on View > Show Console, and running import os; os.environ["PATH"] in that console.

The solution is to make ST use the same PATH that is read by your shell (or OS in general in the case of Windows).

Adjusting PATH can differ based on the operating system and the default shell used. Refer to the following table on where this should be adjusted:

Windows Open Start Menu, type "environment" and select "Edit environment variables for your account". Modify the "Path" variable so that it includes the directory path to the program of your choice.
macOS Depending on your default shell (macOS ships with zsh shell by default), edit: ~/.zprofile (zsh), ~/.profile (bash) or ~/.config/fish/ (fish).
Linux Edit ~/.profile.

For macOS and Linux you can extend the path like so:

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

For package managers like nvm (Node version manager), the recommended way is to insert its initialization script in the respective location specified above.


On macOS, it's enough to restart ST for the changes to be picked up. On other platforms, you might have to re-login your user account.

Another solution could be (at least on Linux) to update the server PATH using the envparameter in your LSP configuration file. The following template can be used where:

  • <your_language_server_name> is the server name
  • <added_path> is the directory needed for the server to behave correctly
    // ...

        "PATH": "<added_path>:/usr/local/bin"

Common problems#

1. LSP doesn't start my language server#

When language server is started, its name appears on the left side of the status bar. If you expect your server to start for a particular file but it doesn't then:

  • Make sure that the root scope (eg. source.php) of the file matches the scope handled by the language server. You can check the root scope of the file by running Show Scope Name from the Tools -> Developer menu. Refer to the documentation of the language server or its own settings to know the expected scope.
  • Make sure that the language server is not disabled globally either in its own settings or in Preferences: LSP Settings, or in the project settings (Project: Edit Project from the Command Palette).

2. LSP cannot find my language server (No such file or directory: 'xyz')#

If you are getting an error that the server binary can't be found but it does start when running it from the terminal, then the issue is likely due to Sublime Text's internal environment not picking up the same PATH environment variable as you've configured in your shell.

See "Updating the PATH used by LSP servers" on how to make Sublime Text aware of the location of your langugage server.

3. Popup error Language server <your_server_language_name> has crashed#

The reason for this can be the same as in problem number 2. Additionally, the language servers may have dependencies that should also be in your PATH in addition to the server binary itself.

For instance if you have installed the haskell-language-server using ghcup-hs you should expose its specific installation folder ~/.ghcup/bin. If the build process uses stack then it should also be in your PATH.

If that doesn't solve the issue, try running LSP: Troubleshoot server and providing its output when asking for help.

Known Issues#

Completions not shown after certain keywords#

Sublime Text's built-in Completion Rules.tmPreferences for some languages suppresses completions after certain keywords. The solution is to put an edited version of the Completion Rules.tmPreferences in the Packages folder (you may need to clear the copy in the Cache folder afterwards).
