PythonShell.runString('x=1+1;print(x)', null).then((messages) => {

2 is shown.

What do you see instead?

$ bun example.js
128 | this.stderrParser = resolve('parse', options.stderrParser || 'text');
129 | this.terminated = false;
130 | this.childProcess = (0, child_process_1.spawn)(pythonPath, this.command, options);
131 | ['stdout', 'stdin', 'stderr'].forEach(function (name) {
132 | self[name] = self.childProcess[name];
133 | self.parser && self[name] && self[name].setEncoding(options.encoding || 'utf8');

TypeError: self[name].setEncoding is not a function. (In 'self[name].setEncoding(options.encoding || "utf8")', 'self[name].setEncoding' is undefined)

Additional information

This is a function supported by NodeJS (see https://nodejs.org/api/stream.html#readablesetencodingencoding), so I presume it should be supported by Bun as well.
