在使用 pyinstaller 制作的可执行文件中使用 pyunpack 并结合 try except [英] Use pyunpack inside an executable file made with pyinstaller in combination with try except
问题描述
我对 pyunpack 有一个奇怪的行为，pyunpack 是一个在可执行文件中用于解包的包.
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，然后解压缩将文件正确放入一个名为grog"的文件夹中，然后我将压缩文件取回原来的名称.
代码如下:
# test.pyfrom os.path import abspath, join, exists, dirname从操作系统导入重命名，mkdir从 Shutil 导入副本导入多处理导入pyunpackmultiprocessing.freeze_support()打印(0)name = "file_to_be_unzipped.sent"打印(一个")path = "C:\\Users\\myname\\eclipse-workspace-tms\\test_unzip_exe"打印(绝对路径(."))打印(b")unzip_dest = join(路径，grog")如果不存在(unzip_dest):mkdir(unzip_dest)打印(c")名称 = 加入(路径，名称)打印(d")打印(e")尝试:打印(1)pyunpack.Archive(name).extractall(unzip_dest)打印(2)除了 pyunpack.PatoolError 作为 ptr:打印(3)temp_f_name = 名称 + ".7z"打印(4)重命名(名称，temp_f_name)尝试:打印(5)pyunpack.Archive(temp_f_name).extractall(unzip_dest)打印(6)重命名(temp_f_name，名称)打印(7)除了 pyunpack.PatoolError 作为 pterr2:# 删除无用的 7z 扩展打印(8)重命名(temp_f_name，名称)打印(9)# 文件已经解压的情况if str(pterr2).find("不是存档"):打印(10)复制(名称，unzip_dest)打印(11)打印(12)除了 ValueError 作为 v:打印(13)打印(五)打印(14)当我启动脚本 test.py 时，我得到了预期的行为:
<代码>0一种C:\Users\myname\eclipse-workspace-tms\test_unzip_exe乙Cd电子134567
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:

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
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规范文件中
("C:\\Users\\myname\\AppData\\Local\\Continuum\\anaconda3\*,'.'")
这将制作一个巨大的可执行文件，或者通过反复试验仅选择必要的文件，这需要很长时间.欢迎任何优雅的解决方案.
EDIT 2:为了更深入地了解，pyunpack 中出现错误的部分位于位于以下位置的 init 文件:
"C:\\Users\\myname\\AppData\\Local\\Continuum\\anaconda3\\Lib\\site-packages\\pyunpack\\__init__.py"
在extract_all_patool函数中:
`p = EasyProcess([sys.executable,patool_path，'--非交互式','提炼'，self.filename,'--outdir=' + 目录# '--详细']).call(timeout=self.timeout) `问题是 sys.executable 设置为 test.exe 文件而不是 python.exe 可执行文件本身
我找到了一个半便携式解决方案，不理想，但我还没有找到更好的:
最终用户希望在默认路径安装anaconda，然后pip install patool和pip install pyunpack，然后将exe文件复制到自己用户名的任意位置文件夹.
我这边:我在规范文件中添加 import pathlib, from pathlib import Path在规范文件的 hidden_mports 列表中，我添加:'pathlib', 'pathlib.Path',
然后在代码中，在print(1)之后，我添加:
abspath = abspath(".")user_path = Path(abspath).partsuser_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)问题是，正如您在第二次编辑中发现的那样，pyunpack 需要 patool 安装在目标系统 - 反过来，它需要 python.
要解决此问题，您需要:
使用压缩包或压缩文件；
shutil支持论文.或者要求最终用户安装 python.
另一种说法是，使用 pyunpack 和 pyinstaller，你需要在目标系统上使用 python.
I have a strange behaviour for pyunpack, a package for unpacking, inside an executable.
I want to do the following thing:
I have a .7z type of file whose ending is not in .7z but in .sent.
First I try to unzip it the direct way, which leads to an expected error that is caught.
Inside this error catching, I am first adding the .7z extension, then I am unzipping the file properly into a folder called "grog", then I give the zipped file its original name back.
Here is the code below:
# 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)
When I launch the script test.py, I get the expected behaviour:
0
a
C:\Users\myname\eclipse-workspace-tms\test_unzip_exe
b
c
d
e
1
3
4
5
6
7
then I build the executable with the following command line:
pyinstaller --log-level=DEBUG test.spec
and the following spec file:

where the file in the destination ("grog") is not an unzipped file as wanted but simply a copy.
Does anybody have an idea of what is going wrong?
Thanks a lot
EDIT:
I have made some progress: In the script, after print(1), if I add:
sys.executable = "C:\\Users\\myname\\AppData\\Local\\Continuum\\anaconda3\\python.exe"
Then it works again. However I have a non portable .exe
Since importing only the python.exe file via the spec file is not enough, the other solution would be to add into the spec file
("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',
Then in the code, after print(1), I am adding:
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)
The problem is, as you found in your 2nd edit, that pyunpack needs patool installed on the target system - which, in turn, requires python.
To fix this you need to:
Use tarballs or zipfiles;
shutilsupports theses.Or require the end user to have python installed.
Another way of putting it is that to use pyunpack with pyinstaller, you need python on the target system.
这篇关于在使用 pyinstaller 制作的可执行文件中使用 pyunpack 并结合 try except的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
