我正在写VS代码扩展到帮助迁移React.createClass到类扩展React.Component。这里的问题是，我无法vscode.commands.executeCommand('vscode.executeFormatDocumentProvider', ...)上班。

请注意，下面的代码是纯 JavaScript，而不是 TypeScript。

function activate(context) {
    context.subscriptions.push(vscode.commands.registerCommand('migrate-to-react-es6-class', () => {

                    const editingRange = document.validateRange(new vscode.Range(0, 0, Number.MAX_SAFE_INTEGER, Number.MAX_SAFE_INTEGER))
                    edit.replace(editingRange, modifiedCode)
                })

                if (document.isUntitled === false) {
                    vscode.commands.executeCommand('vscode.executeFormatDocumentProvider', document.uri, { insertSpaces: true, tabSize: 2 …
