Installing the Slack CLI for Windows
The Slack CLI is a set of tools critical to building workflow apps. This is your one-stop shop for those tools.
✨ If you've not used the Slack CLI before, we recommend following our Deno Slack SDK getting started guide instead. We'll still get your wagon loaded up before you depart for the trail, but we'll also give you some additional guidance.
⤵️ If you need to authorize the Slack CLI, go here.
The minimum required Slack CLI version for Enterprise Grid as of September 19th, 2023 is v2.9.0. If you attempt to log in with an older version, you'll receive a cli_update_required error from the Slack API. Run slack upgrade to get the latest version.
PowerShell is required for installing the Slack CLI on Windows machines. An alternative shell will not work.
- Automated Installation
- Manual Installation
Run the automated installer from Windows PowerShell:
irm https://downloads.slack-edge.com/slack-cli/install-windows.ps1 | iex
PowerShell is required for installing the Slack CLI on Windows machines; an alternative shell will not work.
This will install the Slack CLI and all required dependencies, including Deno, the runtime environment for workflow apps. If you have VSCode installed, the VSCode Deno extension will be installed.
Optional: Use an alias for the Slack CLI binary
If you have another CLI tool in your path called slack, you can rename the slack binary to a different name before you add it to your path.
To do this, copy the Slack CLI into any folder that is already in your path, or add a new folder to your path by listing the folder you installed the Slack CLI to in your Environment Variables. You may not have access to edit System variables, so you might need to add it to your account's User variables. You can open the Environment Variables dialog by pressing the Win+R keys to open the Run window, and then entering the following command:
rundll32.exe sysdm.cpl,EditEnvironmentVariables
You can also use the -Alias flag as described within Optional: customize installation using flags.
Optional: customize installation using flags
There are several flags available to customize the installation. Since flags cannot be passed to remote scripts, you must first download the installation script to a local file:
irm https://downloads.slack-edge.com/slack-cli/install-windows.ps1 -outfile 'install-windows.ps1'
The available flags are:
| Flag | What it does | Example |
|---|---|---|
-Alias | Installs the Slack CLI as the provided alias | -Alias slackcli will create a binary named slackcli.exe and add it to your path |
-Version | Installs a specific version of the Slack CLI | -Version 2.1.0 installs version 2.1.0 of the Slack CLI |
-SkipGit | If true, will not attempt to install Git when Git is not present | -SkipGit $true |
-SkipDeno | If true, will not attempt to install Deno when Deno is not present | -SkipDeno $true |
You can also see all available flags by passing -? to the installation script:
.\install-windows.ps1 -?
Here's an example invocation using every flag:
.\install-windows.ps1 -Version 2.1.0 -Alias slackcli -SkipGit $true -SkipDeno $true
Troubleshooting
Errors
Error: Not working? You may need to update your session's Language Mode.
Solution: For the installer to work correctly, your PowerShell session's language mode will need to be set to FullLanguage. To check your session's language mode, run the following in your PowerShell window: ps $ExecutionContext.SessionState.LanguageMode. To run the installer, your session's language mode will need to be FullLanguage. If it's not, you can set your session's language mode to FullLanguage with the following command: ps $ExecutionContext.SessionState.LanguageMode = "FullLanguage"
1. Download and install Deno. Refer to Install Deno for more details.
2. Verify that Deno is installed and in your path.
The minimum version of Deno runtime required is currently version 1.37.0.
$ deno --version
deno 1.31.1* (release, x86_64-apple-darwin)
v8 10.*
typescript 4.*
3. Download and install
Git, a
dependency of the slack CLI.
4. Download the slack CLI installer for your environment.
5. Add the slack CLI to your path.
Existing slack binary in path?
If you have another CLI tool in your path called slack, we recommend renaming our slack binary to a different name before adding it to your path. See the Automated installation tab for more details.
6. Verify that slack is installed and in your path:
$ slack version
Using slack v2.32.0
7. Verify that all dependencies have been installed.
Run the following command:
$ slack doctor
A few notes about hooks
If you have upgraded your CLI version but your deno-slack-hooks version is less than v1.3.0, when running slack doctor, you will see the following near the end of the output:
✔ Configurations (your project's CLI settings)
Project ID: 1a2b3c4d-ef5g-67hi-8j9k1l2m3n4o
✘ Runtime (foundations for the application)
Error: The `doctor` hook was not found (sdk_hook_not_found)
Suggestion: Ensure this hook is implemented in your `slack.json`
✔ Dependencies (requisites for development)
deno_slack_hooks: 1.2.3 → 1.3.0 (supported version)
In addition, if you attempt to run the slack run command without this dependency installed, you will see a similar error in your console:
🚫 The `start` script was not found (sdk_hook_not_found)
💡 Suggestion
Hook scripts are defined in the Slack configuration file ('slack.json').
Every app requires a 'slack.json' file and you can find a working example at:
https://github.com/slack-samples/deno-starter-template/blob/main/slack.json
Ensure that deno-slack-hooks is installed at the project level and that the version is not less than v1.3.0.
8. Install the VSCode extension for Deno (recommended).
