我正在通过apache服务器运行flask应用程序。
我的应用程序正在使用paramiko模块通过SSH连接到另一台服务器。
当我尝试连接时，我的Apache日志中出现此错误

提及的库位于隐藏的文件夹“ usr / local / lib / python3.5 / dist-packages / .libs_cffi_backend /”中
我已经尝试在使用中设置“ LD_LIBRARY_PATH”：
os.environ['LD_LIBRARY_PATH'] = "/usr/local/lib/python3.5/dist-packages/.libs_cffi_backend/"
我还尝试在/ usr / lib中创建指向它的符号链接
ln -s /usr/local/lib/python3.5/dist-packages/.libs_cffi_backend/ /usr/lib/
，然后运行命令ldconfig。但是我得到这个错误
ldconfig: file /usr/lib/libffi-d77877bc.so.6.0.4 is truncated.
我还使用导出命令设置了“ LD_LIBRARY_PATH”，但无济于事。同样的问题。
这是我使用的代码：
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
ssh.connect(hostname=ip_addr, username=username, password=password)
except:
return 0
感谢您，感谢您。
