:load gives the same error

Having the same error here:

benhili commented 4 years ago

this makes any module with an import statement unusable in tsun for me

RossComputerGuy commented 3 years ago

I'm having the same issue

jq170727 commented 1 year ago

Seeing same problem. For reference here's what I did

% pnpm i -D typescript @types/node tsun
% tsun
  node:internal/fs/utils:346
      throw err;
      ^

Error: ENOENT: no such file or directory, open 'xxx/tsun1/node_modules/.pnpm/tsun @0.5.1_typescript@4.9.5/node_modules/tsun/node_modules/@types/node/index.d.ts'

Looks like this is https://github.com/HerringtonDarkholme/typescript-repl/issues/33

Apply that workaround....

% pushd xxx/tsun1/node_modules/.pnpm/tsun@0.5.1_typescript@4.9.5/node_modules/tsun/node_modules
  xxx/tsun1/node_modules/.pnpm/tsun@0.5.1_typescript@4.9.5/node_modules/tsun/node_modules xxx/tsun1
% ln -s ../../@types .
% popd

Here are the files I'm trying to load.

% cat foo.ts
  import bar from './bar'
  export function foo():string { return bar() }

% cat bar.ts
  export default function bar():string { return "bar says foo!" }

Let's try again

% tsun

  type in TypeScript expression to evaluate
  type :help for commands in repl

  > :help

  tsun repl commands

zx is a little better

% pnpm i -D zx
% zx --repl

  .clear    Alias for .break

  .help     Print this help message
  .load     Load JS from a file into the REPL session
  .save     Save all evaluated commands in this REPL session to a file

  Press Ctrl+C to abort current expression, Ctrl+D to exit the REPL
  ❯ .load foo.ts
  import bar from './bar'
  export function foo():string { return bar() }

  ❯ foo()
  import bar from './bar'
  ^^^^^^

  Uncaught:
  SyntaxError: Cannot use import statement inside the Node.js REPL, alternatively use dynamic import
  ❯

ts-node seems to handle this

% pnpm i -D ts-node
% ts-node
  > .load foo.ts
  import bar from './bar'
  export function foo():string { return bar() }

  > foo()
  'bar says foo!'
  >
