[domasofan]

Hi all,

Just tried to install LibreTranslate 1.5.7 under Windows.
I get some errors which you can see below.
I attached the whole output.

So i created a virtual environment with

$ mkdir libretranslate
$ python -m venv .
$ cd libretranslate
$ pip install libretranslate

[pbanj]

i have the same issue

[grampy]

had the same issue with Phython 3.12.3 but switching to Phyton 3.9.6 allows LibreTranslate to install correctly

[Spy345]

have same issue

[Spy345]

change the pyproject.toml:

"torch ==2.0.1" ==> "torch ==2.3.0"

By doing this above error ie resolved.

[leticiamn]

I had the same issue. With python 3.10.0 it works fine.

https://github.com/LibreTranslate/LibreTranslate/blob/main/CONTRIBUTING.md, check the cmake is installed in your os or not.
This is not a bug. The erros means your os does not installed some needed exe file. you can add shell=true in subprocess.py at line 389(like this : with Popen(*popenargs, **kwargs,shell=True) as p: ) then run pip install libretranslate . it will prompt you that which exe file is not installed. you can download the exe file you needed then installed them. pip install libretranslate will run successfully.
