1.python的版本是3.10.2 2.背景是:想用python+pyqt5来学习python 的GUI编程的, 3.在安装pyqt5-tools时报错如下: C:\Users\bj65d5>pip install pyqt5-tools Collecting pyqt5-tools Using cached pyqt5_tools-5.15.4.3.2-py3-none-any.whl (29 kB) Collecting pyqt5==5.15.4 Using cached PyQt5-5.15.4.tar.gz (3.3 MB) Installing build dependencies ... done Getting requirements to build wheel ... done Preparing metadata (pyproject.toml) ... error error: subprocess-exited-with-error × Preparing metadata (pyproject.toml) did not run successfully. │ exit code: 1 ╰─> [29 lines of output] Traceback (most recent call last): File "C:\Python310\lib\site-packages\pip\_vendor\pep517\in_process\_in_process.py", line 156, in prepare_metadata_for_build_wheel hook = backend.prepare_metadata_for_build_wheel AttributeError: module 'sipbuild.api' has no attribute 'prepare_metadata_for_build_wheel' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\Python310\lib\site-packages\pip\_vendor\pep517\in_process\_in_process.py", line 363, in main() File "C:\Python310\lib\site-packages\pip\_vendor\pep517\in_process\_in_process.py", line 345, in main json_out['return_val'] = hook(**hook_input['kwargs']) File "C:\Python310\lib\site-packages\pip\_vendor\pep517\in_process\_in_process.py", line 160, in prepare_metadata_for_build_wheel whl_basename = backend.build_wheel(metadata_directory, config_settings) File "C:\Users\bj65d5\AppData\Local\Temp\pip-build-env-chamzd56\overlay\Lib\site-packages\sipbuild\api.py", line 51, in build_wheel project = AbstractProject.bootstrap('pep517') File "C:\Users\bj65d5\AppData\Local\Temp\pip-build-env-chamzd56\overlay\Lib\site-packages\sipbuild\abstract_project.py", line 83, in bootstrap project.setup(pyproject, tool, tool_description) File "C:\Users\bj65d5\AppData\Local\Temp\pip-build-env-chamzd56\overlay\Lib\site-packages\sipbuild\project.py", line 594, in setup self.apply_user_defaults(tool) File "C:\Users\bj65d5\AppData\Local\Temp\pip-install-jab1yz7h\pyqt5_cf38f90173ba478693d873275dd5bee7\project.py", line 63, in apply_user_defaults super().apply_user_defaults(tool) File "C:\Users\bj65d5\AppData\Local\Temp\pip-build-env-chamzd56\overlay\Lib\site-packages\pyqtbuild\project.py", line 70, in apply_user_defaults super().apply_user_defaults(tool) File "C:\Users\bj65d5\AppData\Local\Temp\pip-build-env-chamzd56\overlay\Lib\site-packages\sipbuild\project.py", line 241, in apply_user_defaults self.builder.apply_user_defaults(tool) File "C:\Users\bj65d5\AppData\Local\Temp\pip-build-env-chamzd56\overlay\Lib\site-packages\pyqtbuild\builder.py", line 67, in apply_user_defaults raise PyProjectOptionException('qmake', sipbuild.pyproject.PyProjectOptionException [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. error: metadata-generation-failed × Encountered error while generating package metadata. ╰─> See above for output. note: This is an issue with the package mentioned above, not pip. hint: See above for details. 4.遇到问题后从网上搜索解决办法 大都是说需要先安装wheel pip install wheel 但是操作后没有能解决问题 4.1.后来看到一个是说可能是版本兼容的问题 因为3.10.2是目前最高的版本,所以尝试安装3.7.6。 5.最后的解决方法 安装python3.7.6后问题解决,在这里做个记录 |
