DuMate修改Kotti支持python3.12过程中碰到的一些报错

报错：AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?

启动报错

安装这个版本的setuptools搞定

pip install setuptools==70.3.0 -U

但是我原来的是：80.10.2

报错No module named '_sqlite3'

安装sqlite3的开发库

sudo apt-get install libsqlite3-dev

不行。

重新安装新版本的pytest

pip install --upgrade pytest pluggy coverage pytest-cov

Successfully installed coverage-7.13.5 pytest-9.0.3 pytest-cov-7.1.0

这样报错变回到：

报错ModuleNotFoundError: No module named 'pkg_resources'

  File "/home/skywalk/.pyenv/versions/3.12.9/lib/python3.12/site-packages/pyramid/path.py", line 2, in <module>
    import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'

试了重新安装setuptools，还是不行

重新建立虚拟python环境试试，还是一样

后来发现必须要某个特定版本80.10.2

pip install "setuptools==80.10.2" -U

接着处理报错No module named '_sqlite3'

简单测试命令

python3 -c "import sqlite3; print(sqlite3.sqlite_version)"

按照G4F里的解决方案，在Ubuntu下安装全量python3.12

# Example for Ubuntu
sudo apt-get install python3.12-full

不行，还需要继续操作，重新安装pyenv（因为这台系统的额python系统是用pyenv安装的）

# Uninstall the current Python version
pyenv uninstall 3.12.9

# Reinstall with the newly available SQLite libraries
pyenv install 3.12.9

当然我实际安装的是3.12.12版本

pyenv install 3.12

安装完成后，测试一下：

python3 -c "import sqlite3; print(sqlite3.sqlite_version)"

没有输出，证明ok ，问题解决

加入g4f后报错cannot import name 'ContentEditFormBase' from 'kotti.views.edit'

    from kotti.views.edit import ContentEditFormBase
ImportError: cannot import name 'ContentEditFormBase' from 'kotti.views.edit' (G:\dumatework\Kotti\kotti\views\edit\__init__.py)

    from kotti.views.edit import ContentEditFormBase
ImportError: cannot import name 'ContentEditFormBase' from 'kotti.views.edit' (G:\dumatework\Kotti\kotti\views\edit\__init__.py)

问题原因： 模板使用了 request.macros['page']，但 Kotti 使用的是 api.macro() 方法。

修复内容： 将模板改为使用 Kotti 标准模板模式：

metal:use-macro="api.macro('kotti:templates/view/master.pt')"

虚拟环境中重新安装 kotti_g4f：

cd G:\dumatework\kotti_g4f
pip install -e .

然后重新启动 Kotti ，问题解决！

总结：

No module named '_sqlite3'

先用测试命令

python3 -c "import sqlite3; print(sqlite3.sqlite_version)"

ModuleNotFoundError: No module named 'pkg_resources' 

当前是使用的特定版本的setuptools解决

pip install "setuptools==80.10.2" -U
