在使用 pyinstaller 制作的可执行文件中使用 pyunpack 并结合 try except

Question

我对 pyunpack 有一个奇怪的行为，一个用于解包的包，在一个可执行文件中。

我想做以下事情：

我有一个 .7z 类型的文件，其结尾不是 .7z 而是 .sent。

首先，我尝试以直接方式解压缩它，这会导致捕获到预期的错误。

在此错误捕获中，我首先添加 .7z 扩展名，然后将文件正确解压缩到名为“grog”的文件夹中，然后将压缩文件的原始名称恢复为原来的名称。

这是下面的代码：

# test.py
from os.path import abspath, join, exists, dirname
from os import rename, mkdir
from shutil import copy
import multiprocessing
import pyunpack

multiprocessing.freeze_support()
print(0)
name = "file_to_be_unzipped.sent"
print("a")
path = "C:\\Users\\myname\\eclipse-workspace-tms\\test_unzip_exe"
print(abspath("."))
print("b")
unzip_dest = join(path, "grog")
if not exists(unzip_dest):
    mkdir(unzip_dest)
print("c")
name = join(path, name)
print("d")
print("e")
try:
    print(1)
    pyunpack.Archive(name).extractall(unzip_dest)
    print(2)
except pyunpack.PatoolError as pterr:
    print(3)
    temp_f_name = name + ".7z"
    print(4)
    rename(name, temp_f_name)
    try:
        print(5)
        pyunpack.Archive(temp_f_name).extractall(unzip_dest)
        print(6)
        rename(temp_f_name, name)
        print(7)
    except pyunpack.PatoolError as pterr2:
        # removing useless 7z extension
        print(8)
        rename(temp_f_name, name)
        print(9)
        # Case when the file is already unzipped
        if str(pterr2).find("Is not archive"):
            print(10)
            copy(name, unzip_dest)
            print(11)
        print(12)
except ValueError as v:
    print(13)
    print(v)
    print(14)

当我启动脚本 test.py 时，我得到了预期的行为：

0
a
C:\Users\myname\eclipse-workspace-tms\test_unzip_exe
b
c
d
e
1
3
4
5
6
7

然后我使用以下命令行构建可执行文件：

pyinstaller --log-level=DEBUG test.spec

以及以下规范文件：

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None

然后在意外的很长时间之后，我得到以下信息：

b
c
d
e

2

其中目标（“grog”）中的文件不是所需的解压缩文件，而只是一个副本。

有人知道出了什么问题吗？

非常感谢

编辑：

我取得了一些进展：在脚本中，在 print(1) 之后，如果我添加：

sys.executable = "C:\\Users\\myname\\AppData\\Local\\Continuum\\anaconda3\\python.exe"

然后它再次工作。但是我有一个不可移植的 .exe

由于仅通过spec文件导入python.exe文件是不够的，另一种解决方案是添加到spec文件中

("C:\\Users\\myname\\AppData\\Local\\Continuum\\anaconda3\*,'.'")

which is going to make a huge executable, or pick one by one only the necessary files through trial and error, which takes ages. Any elegant solution is welcome.

EDIT 2: For more insight, the part from the pyunpack where the bug occurs is at the init file located in:

"C:\\Users\\myname\\AppData\\Local\\Continuum\\anaconda3\\Lib\\site-packages\\pyunpack\\__init__.py"

in the function extract_all_patool:

   `p = EasyProcess([
        sys.executable,
        patool_path,
        '--non-interactive',
        'extract',
        self.filename,
        '--outdir=' + directory
        # '--verbose'
    ]).call(timeout=self.timeout) `

the problem being that sys.executable is set to the test.exe file instead of the python.exe executable itself

EDIT3: I found a semi-portable solution, not ideal but I found nothing better yet:

The end-user is expected to install anaconda in the default path, then pip install patool and pip install pyunpack, and then copy the exe file anywhere in his username folder.

On my side: I am adding in the spec file import pathlib, from pathlib import Path In the hidden_mports list of the spec file, I am adding: 'pathlib', 'pathlib.Path',

然后在代码中，之后print(1)，我添加：

abspath = abspath(".")
user_path = Path(abspath).parts
user_path = join(user_path[0], user_path[1], user_path[2], user_path[3] )
conda_path = join("AppData", "Local", "Continuum", "anaconda3", "python.exe")
sys.executable = join(user_path, conda_path)

Answer 1

print(abspath("."))直接在python中运行时的输出是：

C:\Users\myname\eclipse-workspace-tms\test_unzip_exe

使用 pyinstaller 运行时是：

C:\Users\myname\eclipse-workspace-tms\test_unzip_exe\dist\test

因此，存档不会提取到dist\test文件夹中。

通过设置path返回值abspath(".")而不是硬编码来修复此问题C:\Users\myname\eclipse-workspace-tms\test_unzip_exe
