未能为Opencv构建车轮
未能为Opencv构建车轮
提问于 2022-04-14 10:47:40
我用下面的命令将轮子、pip和setuptools升级到最新版本。
pip3.9 install --upgrade pip setuptools wheel
当我尝试安装opencv pip3.9 install opencv-python时，会出现一个错误。我试着安装一个旧版本，得到了相同的错误(4.5.5.62)。这是我遇到的错误，请看一看，谢谢！
Python版本: 3.9 (opencv-python在3.8岁时工作)
应用: PyCharm

通过检查函数cls.wraps._classify_installed_files的源。
print(inspect.getsource(cls.wraps._classify_installed_files))我发现原因是函数定义中没有名为cmake_install_dir的参数，而是_cmake_install_dir参数。
def _classify_installed_files(
install_paths,
package_data,
package_prefixes,
py_modules,
new_py_modules,
scripts,
new_scripts,
data_files,
cmake_source_dir,
_cmake_install_dir,
):
assert not os.path.isabs(cmake_source_dir)
assert cmake_source_dir != "."
install_root = os.path.join(os.getcwd(), CMAKE_INSTALL_DIR())
......因此，我将命名参数cmake_install_dir更改为_cmake_install_dir。然后通过了！
return (cls.wraps._classify_installed_files)(
final_install_paths,
package_data,
package_prefixes,
py_modules,
new_py_modules,
scripts,
new_scripts,
data_files,
# To get around a check that prepends source dir to paths and breaks package detection code.
cmake_source_dir="",
_cmake_install_dir=cmake_install_reldir,
