Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

I'm having the above problem when installing according to your method (python version 3.9.5), do you know how to fix it?

[haidi-ustc]

make sure that you have install the setuptools-scm by : pip install setuptools-scm If this problem still can't be solved, just comment the scm related lines in setup.py

use_scm_version={'write_to': 'mech2d/_version.py'},

setup_requires=['setuptools_scm'],

I met the same error report as obaica which commented on Nov 20, 2021. But the new code doesn't have setup.py.

[haidi-ustc]

@ji-0226 Since you downloaded the mech2d package as a zip file and not via Git, the mech2d-master.zip file lacks the necessary metadata for versioning. To resolve this issue, you have two options:

1. Use Git to Clone the Repository: This method ensures that all the necessary metadata, including version information, is present. You can clone the repository and install the package using the following commands:

   git clone git@github.com:haidi-ustc/mech2d.git
   cd mech2d
   pip install .

2. Modify the pyproject.toml File: If cloning the repository is not feasible, you can manually adjust the pyproject.toml file to bypass the need for Git metadata. Here's how you can modify it:

   
   [build-system]
   requires = ["setuptools>=61" ]
   build-backend = "setuptools.build_meta"

[project] version="0.3.0" name = "mech2d" requires-python = ">=3.8" keywords = ["2D materials", "mechanical properties", "DFT"] description = "mech2d: a calculator for two dimensional material mechanical properties" authors = [ {name = "Haidi Wang", email = "haidi@hfut.edu.cn"}, ] license = {file = "LICENSE"} classifiers = [ "Programming Language :: Python :: 3.8", "Programming Language :: Python :: 3.9", "Programming Language :: Python :: 3.10", "License :: OSI Approved :: GNU Lesser General Public License v3 (LGPLv3)", ] dependencies = [ 'numpy>=1.21.2', 'pymatgen==2023.7.17', 'dpdispatcher==0.3.39', 'custodian==2021.2.8' ] readme = "README.md"

hi, I have installed mech2d but after following command:m2d -h I get this error:

         ^^^^^^^^^^^^^^^^^^
SyntaxError: invalid syntax. Maybe you meant '==' or ':=' instead of '='?

[haidi-ustc]

The bug indicates that there is invalid syntax in line 228 of plot.py. However, upon inspection, I found that the source file of plot.py only contains 225 lines. I suspect that plot.py was unintentionally altered. Try reinstalling, and if that doesn't resolve the issue, consider replacing the plot.py in the error path with the one from GitHub.

Thank you, I installed version 0.4; The error is solved, but I get the following error:

/home/shahram/.local/lib/python3.10/site-packages/matplotlib/projections/__init__.py:63: UserWarning: Unable to import Axes3D. This may be due to multiple versions of Matplotlib being installed (e.g. as a system package and as a pip package). As a result, the 3D projection is not available.

Desctiption:
------------
mech2d is a convenient script that use to calculate the mechanical properties of
2D materials, including Stress-Strain Curve, elastic constants and revalant
properties. The script works based on several sub-commands with their own options.
To see the options for the sub-commands, type "m2d sub-command -h".

positional arguments:
  {init,run,post}
    init           Generating initial data for elastic systems.
    run            Run the DFT calculation for deformed structures.
    post           Post processing for elastic calculation.

options:
  -h, --help       show this help message and exit
  -v, --version    Display version

@shahramyalameha I have tried to install the mech2d again and find no error. please try to use conda envirment to install the mech2d:

conda create -n vmech2d python=3.10
conda activate vmech2d
 git clone git@github.com:haidi-ustc/mech2d.git
 cd mech2d
 pip install .
