Contributing

  • If you want to develop and debug this extension from source code, and run 'npm install' under the root dir of this extension,

  • npm packages vscode and typescript is needed as an environment

    npm install vscode
npm install typescript

  • Cannot find module 'vscode'? Please run 'npm run postinstall' under the root dir of this extension, according to Cannot find module 'vscode' – where is vscode.d.ts now installed? #2810

    • Error installing vscode.d.ts: Error: connect ETIMEDOUT 51.144.164.215:443
      • npm use npm proxy instead of HTTP_PROXY, so proxy takes no effect if npm_proxy is not set

        • set proxy for npm

          npm config set proxy http://username:password@proxy_server:proxy_port
npm config set https-proxy http://username:password@proxy_server:proxy_port

        • another way, run 'npm_config_proxy="http://username:password@proxy_server:proxy_port" npm_config_https_proxy="http://username:password@proxy_server:proxy_port" npm run postinstall' instead(npm_config_https_proxy can be ignored if npm_config_https_proxy is the same as npm_config_proxy).

        • execute sudo command with proxy, accroding to Pro Terminal Commands: How and Why To Edit Sudoers on macOS
