При компиляции этого фрагмента кода TS C продолжает возвращать ошибку:
let message = 'abc';
message.endsWith('c');
В основном компилятор не может найти метод endsWith() для строки типа. Эта же ошибка также возвращается парсером машинописного текста , который я установил для атома . Я понимаю, что это происходит потому, что компилятор нацелен на версию Javascript, в которой нет этого метода для этого типа, который был представлен ES6. Действительно, компиляция с помощью команды tsc --target ES6 code.ts не возвращает никаких ошибок. Однако я бы хотел изменить целевую версию Javascript на более новую, чтобы мне не приходилось каждый раз указывать целевую версию. Это можно сделать в рамках проекта, создав tsconfig. json файл , но есть ли способ изменить его глобально для любого будущего проекта, чтобы мне больше не приходилось об этом беспокоиться?
РЕДАКТИРОВАТЬ: это мой tsconfig. json
{
"compilerOptions": {
"target": "es2020"
}
}
Если он находится в том же каталоге, что и проект, вызов команды tsc в этом каталоге работает отлично. Кроме того, анализатор Atom перестает сигнализировать об ошибке, описанной ранее.
Однако я бы хотел, чтобы этот параметр был действителен для любого проекта машинописного текста, который я мог бы начать в будущем. Поскольку ts c ищет файл tsconfig. json, начиная с заданного каталога и затем поднимаясь по иерархии, размещение этого файла tsconfig. json в каталоге, в котором размещены все каталоги моих проектов, должно решить мою проблему. Однако вместо этого я получаю кучу ошибок, связанных с angular.
