运行 PyInstaller 生成的二进制文件时出现模块导入错误

问题描述

我在 RHEL X64 上尝试使用 PyInstaller 执行简单的 hello.py 时遇到错误.

I'm getting an error while trying to a simple hello.py using PyInstaller on RHEL X64.

Python 2.7.12 安装在/opt/python

Python 2.7.12 is alt installed in /opt/python

编译输出:

Hello.py:

print("Hello")

这是我得到的错误:

  File "/opt/python/lib/python2.7/struct.py", line 1, in <module>
    from _struct import *

有什么线索可能导致这种情况吗?

Any clue what may be causing this?

自动生成的 Hello.spec 文件如下所示:

The auto-generated Hello.spec file looks like this:

# -*- mode: python -*-

block_cipher = None


a = Analysis(['Hello.py'],
             pathex=['/home/myuser/CommandManager'],
             binaries=None,
             datas=None,
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='Hello',
          debug=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               name='Hello')

推荐答案

PyInstaller 需要用 --enable-shared 和 LDFLAGS=-Wl,-rpath= 编译 python代码>.

PyInstaller needs python to be compiled with --enable-shared and LDFLAGS=-Wl,-rpath=<path to python lib>.

就我而言:

./configure --enable-shared --prefix=/opt/pythonLDFLAGS=-Wl,-rpath=/opt/python/lib
