只需尝试一个官方文档网站示例:
from pysnmp.hlapi import *
errorIndication, errorStatus, errorIndex, varBinds = next(
getCmd(SnmpEngine(),
CommunityData('public'),
UdpTransportTarget(('192.168.1.14', 161)),
ContextData(),
ObjectType(ObjectIdentity('1.3.6.1.2.1.1.1.0')))
)
if errorIndication:
print(errorIndication)
elif errorStatus:
print('%s at %s' % (
errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex)-1][0] or '?'
)
)
else:
for varBind in varBinds:
print(' = '.join([ x.prettyPrint() for x in varBind ]))
我们可以看到它通过Python解释器执行时确实有效:
(Compiler)[user@machine testSNMP]$ python testSNMP.py
SNMPv2-MIB::sysDescr."0" = 48-port 10/100/1000 Gigabit Switch
然而,如果我试图"冻结"它与PyInstaller(PyInstaller --onefile)一旦执行它我得到以下错误:
(Compiler)[user@machine testSNMP]$ /lab/testSNMP/dist/testSNMP
Traceback (most recent call last):
File "<string>", line 4, in <module>
File "/lab/testSNMP/build/testSNMP/out00-PYZ.pyz/pysnmp.entity.engine", line 83, in __init__

pysnmp.smi.error.MibNotFoundError: No module __SNMP-FRAMEWORK-MIB loaded at <pysnmp.smi.builder.MibBuilder instance at 0x179f518>
pysnmp / smi / mibs中的强制文件似乎未明确导入以供使用。这就是为什么我分阶段拆分构建过程的原因。拳头,创建规范文件。
(Compiler)[user@machine testSNMP]$ pyi-makespec --onefile getInterfaces.py
wrote /lab/testSNMP/getInterfaces.spec
now run pyinstaller.py to build the executable
然后,我已经对其进行了编辑,以便根据其他堆叠帖子(Can't get pysnmp to work with pyinstaller)中的建议导入所需文件:
# -*- mode: python -*-
import PyInstaller.hooks.hookutils
hiddenimports = ['pysnmp.smi.exval','pysnmp.cache'] + PyInstaller.hooks.hookutils.collect_submodules('pysnmp.smi.mibs') + PyInstaller.hooks.hookutils.collect_submodules('pysnmp.smi.mibs.instances')
a = Analysis(['testSNMP.py'],
pathex=['/lab/testSNMP'],
hiddenimports=hiddenimports,
hookspath=None,
runtime_hooks=None)
x = Tree('/virtualenvs/Compiler/lib/python2.7/site-packages/pysnmp/smi/mibs',prefix='pysnmp/smi/mibs',excludes='.py')
pyz = PYZ(a.pure)
exe = EXE(pyz,
a.scripts,
a.binaries,
a.zipfiles,
a.datas,
x,
name='testSNMP',
debug=False,
strip=None,
upx=True,
console=True )
但是,一旦它被构建并执行,我就会收到另一个错误:
(Compiler)[user@machine testSNMP]$ /lab/testSNMP/dist/testSNMP

我还能做什么?提前谢谢!

为了让Jeremy的答案变得便携,您可以修改您的spec文件,如下所示:
+ import os.path
+ import pysmi
+ import pysnmp.smi.mibs
+ def module_base(module):
+ return os.path.abspath(os.path.join(module.__file__, os.pardir))
coll = COLLECT(
exe,
a.binaries,
a.zipfiles,
a.datas,
+ Tree(module_base(pysmi), prefix='pysmi'),
+ Tree(module_base(pysnmp.smi.mibs), prefix='pysnmp/smi/mibs'),
...
编辑: 结果将这些添加到hiddenimports解决了我的问题:
'pysnmp.smi.mibs', 'pysnmp.smi.mibs.instances', 'pysnmp.smi.exval', 'pysnmp.cache'
答案 1 :(得分:1)
我遇到了同样的问题,并设法通过将pysmi
文件包含在树中来实现它,就像pysnmp mib一样。
我的pyinstaller spec文件最终结果如下:
...
x = Tree(os.getcwd()+'/.pyenv/Lib/site-packages/pysnmp/smi/mibs',prefix='pysnmp/smi/mibs')
y = Tree(os.getcwd()+'/.pyenv/Lib/site-packages/pysmi',prefix='pysmi')
...
exe = EXE(pyz,
a.scripts,
a.binaries,
a.zipfiles,
a.datas,
x,y,
...
虽然这有效但我实际上是通过使用不依赖于pysmi的旧版本的pysnmp v4.2.5以另一种方式解决了它
答案 2 :(得分:1)
得到了同样的错误&#34;无法获得源代码&#34;。在Pyinstaller github页面上创建了一个问题: https://github.com/pyinstaller/pyinstaller/issues/1945 解决方案是将ply包含到spec文件中,如您在上面提到的链接中所述: Can't get pysnmp to work with pyinstaller 通过添加&#34; PyInstaller.utils.hooks.collect_submodules(&#39; ply&#39;)&#34;到hiddenimports
并确保ply版本为&gt; = 3.9!
除了分析部分之外,我的spec文件看起来几乎相同:
a = Analysis(['main.py'],
binaries=None,
datas=PyInstaller.utils.hooks.collect_data_files('pysnmp') + \
hiddenimports=PyInstaller.utils.hooks.collect_submodules('pysmi')+\
PyInstaller.utils.hooks.collect_submodules('ply') + \
PyInstaller.utils.hooks.collect_submodules('pyasn1') + \
PyInstaller.utils.hooks.collect_submodules('pysnmp'),
hookspath=None,
runtime_hooks=None,
excludes=None,
win_no_prefer_redirects=None,
