No such file or directory: 'c:\\test_project\\venv\\scripts\\pyinstaller.exe\\__main__.pyo'

[xOctave]

Hello,

I encounter a problem when running fbs freeze on a test project with just a few dependencies. The process stops stating that it cannot find pyinstaller.exe\__main__.pyo

FileNotFoundError: [Errno 2] No such file or directory: 'c:\\test_project\\venv\\scripts\\pyinstaller.exe\\__main__.pyo'

I read all the documentation and troubleshooting carefully, and solved all my dependencies problem by myself.

My setup

• operating system(s) Windows 10
• Python version 3.6 vanilla
• fbs 0.83
• PyInstaller 3.5
• PyQt5 5.13.0

PS - Thanks a lot for this awesome fbs stack by the way.

[mherrmann]

Interesting. Some other people reported this - with fbs - on PyInstaller's issue tracker. I'll have a look when I find time.

[mherrmann]

@hsq125 do you have a minimal example that reproduces the problem?

[xOctave]

Thanks a lot for answering. Yes, I also found pyinstaller/pyinstaller#3977.

I'll try to clean up my project just right now to create a minimal example.

@mherrmann Here is a minimal example fbs-freeze.zip

It looks like adding any dependency to a empty project leads to the issue.

Here is the procedure I followed to create the minimal project and reproduce the problem

1. Create project folder, for example fbs-freeze
2. Go in folder fbs-freeze
3. Create virtual environment with python -m venv v1
4. Activate virt env v1\Script\activate.bat
5. fbs startproject
6. So far, everything will be OK - if you run fbs freeze --debug, it will finish and produce an .exe
7. add import numpy in main.py, and run fbs freeze --debug again -> it will produce the reported error.
8. remove the import line, and it is working again.

---

Additionnal info, my virtual environment is
(v1) C:\fbs-freeze>pip list --local
Package Version
numpy 1.16.4
pip 18.1
PyQt5 5.13.0
PyQt5-sip 4.19.18
setuptools 40.6.2

Thanks for your help!

@rich678s Do you really expect me to read through all this output? Paste a minimal example that reproduces the problem here, or ask on StackOverflow. This space is for bugs in fbs, not "I have a problem with my script". Unless you can convince me that what you are experiencing is a bug in fbs, and not a problem of your code, I have better things to do in my spare time than to help you.

[mherrmann]

I guess I was a bit too harsh in my reply, sorry. I hadn't considered the context. But still, I feel like your message lacks a lot of context. The fact that you have openpyxl in there shows that it's a dump from your project, not from @hsq125's minimal example. It's too little information (and in too much text) for me to be able to help you.

[xOctave]

@mherrmann If I may suggest an hypothesis -> I think that the problem arise as soon as you add a dependency in the project, whatever it is (could be pillow, numpy, six ... whatever).

I went through the output of the "fbs freeze --debug", and I see (maybe you will say that it is obvious) that the freeze command is doing additional things when the project include external dependencies.

The problem is located in this part of the code (maybe in the PyInstaller hooks provided by fbs?) I'm really not an expert in that - I try to debug it, but without success so far :(

unfortunately I do not have a minimum working example. for me fbs freeze works normally, but when I do fbs freeze --debug I get this error. If I can't find a solution I'll come up with a minimal example and post it here.

Edit:I made a quick edit to the pip install files to follow the advice given here: pyinstaller/pyinstaller#3977 (comment) this eliminated the error.

[mherrmann]

@hsq125 I cannot reproduce the problem. Here's what I tried:

OS: WIndows 7
Python 3.6

python -m venv venv
call venv\Scripts\activate.bat
pip install fbs PyQt5==5.9.2 numpy==1.16.2
fbs startproject
# Add `import numpy` to src/main/python/main.py
fbs freeze --debug
target\MyApp\MyApp

No problems.

[Aperion]

@mherrmann Given your example I do get the error, however I am running Python 3.7. I edit venv/Lib/site-packages/fbs/freeze/__init__.py to the following: https://gist.github.com/Aperion/daf314c286a94ec5e41e01b5b79ef8b8

After such a time called fbs freeze --debug gets the same error, but replace pyinstaller with fbs if I instantiate fbs via python -m fbs freeze --debug everything works fine. it seams there two issues are related.

[mherrmann]

I'm afraid I don't quite understand your comment @Aperion. And I don't want to spend further time thinking about it, because you are using Python 3.7, which I do not yet support. Feel free to post back here if you have information about the supported Python versions 3.5 and 3.6.

[Akashpanchal95]

@mherrmann When I import the pytz library. I got a similar error.

System Configuration

operating system(s) Windows 10
Python version 3.6
fbs 0.8.3
PyInstaller 3.5
PyQt5 5.9.2
pytz 2019.2

[mherrmann]

@Akashpanchal95 Do you also get this error with PyInstaller 3.4 and if you repeat these steps with pytz instead of numpy?

[Akashpanchal95]

I have checked with PyInstaller 3.4. Now it's working. Thanks for your help.

[mherrmann]

I have checked with PyInstaller 3.4. Now it's working.

And this, to everyone reading this, is why I'm so adamant about only using officially supported versions with fbs. At the time of this writing:

• Python 3.5 or 3.6
• PyInstaller 3.4
• PyQt5 5.9.2

Everything else is unsupported and can (and often does) lead to problems.
