[英]Python: ftfy causes app crash when compiled to exe using pyinstaller, cx_freeze or p2exe
Whenever I import ftfy
, and use it in my python script apps, I have no problems at all. 每当我导入
ftfy
,并在我的python脚本应用程序中使用它时,我都没有任何问题。
If I compile to binary exe using pyinstaller
, cx_freeze
or py2exe
, my app will compile without problems, but crashes every time time when I run the app. 如果我使用
pyinstaller
, cx_freeze
或py2exe
编译为二进制exe,则我的应用程序将毫无问题地进行编译,但是每次运行该应用程序时都会崩溃。
The reason it crashes is because it cannot find the char_classes.dat
file from chardata.py
. 它崩溃的原因是因为它无法从
chardata.py
找到char_classes.dat
文件。
Here is a typical output that I get when I run my app after compiling with pyinstaller and it crashes: 这是使用pyinstaller编译后运行我的应用程序时崩溃的典型输出:

FileNotFoundError:[错误2]没有这样的文件或目录:'C:\\ Users \\ BILLTH〜1 \\ Ap pData \\ Local \\ Temp \\ _MEI64282 \\ ftfy \\ char_classes.dat'
d2e returned -1
d2e返回-1
This output says that it cannot find the char_classes.dat
file even though that file is there -- as plain as day -- within the ftfy module in the site-packages directory. 此输出表明,即使该文件存在于site-packages目录中的ftfy模块中,也无法找到
char_classes.dat
文件(就像平常一样)。
According to your log, the file looked for is C:\\Users\\BILLTH~1\\AppData\\Local\\Temp\\_MEI64282\\ftfy\\char_classes.dat
. 根据您的日志,查找的文件是
C:\\Users\\BILLTH~1\\AppData\\Local\\Temp\\_MEI64282\\ftfy\\char_classes.dat
。
As it is a temporary directory, I guess that it is where the archive was extracted. 由于它是一个临时目录,所以我想它是提取存档的位置。 These compiler tools create an auto-extractable zip archive which extracts the sources and the embeded python interpreter in a temporary folder, sets up some environment variables, and runs python with the right parameters.
这些编译器工具会创建一个可自动提取的zip归档文件,该文件可将源文件和python解释器提取到一个临时文件夹中,设置一些环境变量,并使用正确的参数运行python。
Therefore, I guess that your char_classes.dat
file was not embeded by the tool, probably because the tool doesn't see the dependency. 因此,我猜您的
char_classes.dat
文件没有被该工具嵌入,可能是因为该工具没有看到依赖关系。
Using pyinstaller, you will probably find the section of the documentation Using Data Files from a Module interesting, and add the following argument to your Analysis
call: 使用pyinstaller,您可能会发现文档“ 使用模块中的数据文件 ”部分很有趣,并将以下参数添加到
Analysis
调用中:
datas=[('ftfy\char_classes.dat', 'ftfy')]
I've found a limited solution to this issue. 我已经找到了解决此问题的有限方法。
For me, I was unable to get Using Data Files from a Module to work. 对我来说,我无法从“模块中使用数据文件”正常工作。 I also had no luck with any kind of data specification from a hook file.
我也对钩子文件中的任何数据规范都不走运。
However, it worked using a relative path from my .spec file (which is automatically created in the working directory where you run PyInstaller). 但是,它使用我的.spec文件(在运行PyInstaller的工作目录中自动创建)的相对路径来工作。
In my case, 就我而言
a = Analysis(['ShellClient.py'],
pathex=['C:\\workspaces\\ScoutSheet\\ScoutSheet\\ScoutSheet.Parsers.NERParsers'],
binaries=[],
datas=[
("./env/Lib/site-packages/ftfy/char_classes.dat", "ftfy")
],
hiddenimports=["ftfy"],
hookspath=['.\\PyinstallerHooks'],
runtime_hooks=[],
excludes=[],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher)
The important line being 重要的是
datas=[
("./env/Lib/site-packages/ftfy/char_classes.dat", "ftfy")
],
