【问题描述】：
我在 Windows 上创建了一个脚本来连接到远程 SSH 服务器。我已经成功安装了cryptography、pynacl，最后是paramiko（花了我一整天的时间来弄清楚如何在 Windows 上成功安装它们）。
现在我运行脚本，它会弹出一个错误，指出 DLL 加载失败。该错误似乎与libsodium 有关，但我无法准确确定要尝试加载的DLL 以及从何处加载。为了安全起见，我还安装了pysodium。
这是脚本：
automate.py
import SSH
connection = ssh("10.10.65.100", "gerrit2", "gerrit@123")
print("Calling OpenShell")
connection.openShell()
print("Calling sendShell")
connection.sendShell("ls -l")
print("Calling process")
connection.process()
print("Calling closeConnection")
connection.closeConnection()
SSH.py
import threading, paramiko
class ssh:
shell = None
client = None
transport = None
def __init__(self, address, username, password):
print("Connecting to server on ip", str(address) + ".")
self.client = paramiko.client.SSHClient()
self.client.set_missing_host_key_policy(paramiko.client.AutoAddPolicy())
self.client.connect(address, username=username, password=password, look_for_keys=False)
self.transport = paramiko.Transport((address, 22))
self.transport.connect(username=username, password=password)
thread = threading.Thread(target=self.process)
thread.daemon = True
thread.start()
def closeConnection(self):
if(self.client != None):
self.client.close()
self.transport.close()
def openShell(self):
self.shell = self.client.invoke_shell()
def sendShell(self, command):
if(self.shell):
self.shell.send(command + "\n")
else:
print("Shell not opened.")
def process(self):
global connection
while True:
# Print data when available
if self.shell != None and self.shell.recv_ready():
alldata = self.shell.recv(1024)
while self.shell.recv_ready():
alldata += self.shell.recv(1024)
strdata = str(alldata, "utf8")
strdata.replace('\r', '')
print(strdata, end = "")
if(strdata.endswith("$ ")):
print("\n$ ", end = "")
这是错误：

【问题讨论】：

好像 pynacl 没有安装好。无法找到其扩展模块之一（或其某些 .dll 依赖项）。您应该能够通过以下方式重现该问题：
import paramiko。顺便说一句：你的路径中的 Python37 是什么？ -
@CristiFati : 我做了
where python并收到了这条路径D:\Users\prashant-gu\AppData\Local\Programs\Python\Python37\python.exe -
@CristiFati：谢谢你给我的线索。费了好大劲，终于解决了这个问题。
