But it there seems to be an issue what we can't import several standard libraries. For example:\r\n\r\n```\r\n└─\u003e curl -X POST https://untrusted-python.fly.dev/api/exec \\\r\n-H \"Content-Type: application/json\" \\\r\n-d '{\"code\":\"import datetime\"}'\r\n\r\nTraceback (most recent call last):\r\n  File \"/app/./sandbox.py\", line 41, in \u003cmodule\u003e\r\n  File \"\u003cstring\u003e\", line 1, in \u003cmodule\u003e\r\nModuleNotFoundError: No module named 'datetime'\r\n```\r\n\r\nAfter checking around I can see the issue is because some permissions are missing. After disabled the [drop_perms()](https://github.com/healeycodes/untrusted-python/blob/main/sandbox/sandbox.py#L40) function, it works well. Like this:\r\n\r\n```\r\nif __name__ == \"__main__\":\r\n    code = sys.argv[1]\r\n    set_mem_limit()\r\n    # drop_perms()\r\n    exec(code)\r\n```\r\nThen it works:\r\n```\r\n└─\u003e curl -X POST http://localhost:3000/api/exec \\\r\n-H \"Content-Type: application/json\" \\\r\n-d '{\"code\":\"import datetime\\nprint(1)\"}'\r\n1\r\n\r\n```\r\n\r\nSo ideally we should improve this function to let all default Python's functionality work well.\r\n","author":{"url":"https://github.com/mozedz","@type":"Person","name":"mozedz"},"datePublished":"2023-12-28T06:59:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/1/untrusted-python/issues/1"}
