Sorry, I have not found any guide on install new package in langchain-sandbox so I try these code

from langchain_sandbox import PyodideSandbox

# Create a sandbox instance
sandbox = PyodideSandbox(
   "./sessions", # Directory to store session files
   # Allow Pyodide to install python packages that
   # might be required.
   allow_net=True,
)
code = """\
!pip install openai
"""

# Execute Python code
print(await sandbox.execute(code, session_id="123"))

And got these error:

CodeExecutionResult(result=None, stdout=None, stderr='Traceback (most recent call last):\n  File "/lib/python312.zip/_pyodide/_base.py", line 597, in eval_code_async\n    await CodeRunner(\n          ^^^^^^^^^^^\n  File "/lib/python312.zip/_pyodide/_base.py", line 285, in __init__\n    self.ast = next(self._gen)\n               ^^^^^^^^^^^^^^^\n  File "/lib/python312.zip/_pyodide/_base.py", line 149, in _parse_and_compile_gen\n    mod = compile(source, filename, mode, flags | ast.PyCF_ONLY_AST)\n          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n  File "<exec>", line 1\n    !pip install openai\n    ^\nSyntaxError: invalid syntax\n', status='error', execution_time=5.070329904556274)
