PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.8/dist-packages/grpc/__init__.py'

Question

我在我的 app.py 中使用 grpc，我將使用 Gramine 在 SGX 中運行 app.py，當我運行命令gramine-sgx./python app.py"時，我得到錯誤：

Traceback (most recent call last):
  File "app.py", line 2, in <module>
    import grpc
  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 671, in _load_unlocked
  File "<frozen importlib._bootstrap_external>", line 844, in exec_module
  File "<frozen importlib._bootstrap_external>", line 980, in get_code
  File "<frozen importlib._bootstrap_external>", line 1037, in get_data
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.8/dist-packages/grpc/__init__.py'
Error in sys.excepthook:

  File "/usr/lib/python3/dist-packages/apt/__init__.py", line 36, in <module>
    apt_pkg.init_system()
apt_pkg.Error: E:Error reading the CPU table

Original exception was:
Traceback (most recent call last):
  File "app.py", line 2, in <module>
    import grpc
  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked

  File "<frozen importlib._bootstrap_external>", line 1037, in get_data
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.8/dist-packages/grpc/__init__.py'

我檢查了 init.py 的權限，我什至嘗試使用 sudo 運行代碼，但出現了同樣的錯誤

將 /usr/local/lib/python3.8/dist-packages/grpc/ 添加到清單中的受信任文件解決了這個問題。
