一文解决Could not build wheels for box2d-py, which is required to install pyproject.toml-based projects

问题描述

windows11下，使用anaconda在虚拟环境下下载gymnasium[all]库报错.

过程：

首先用conda指令下载发现报错未找到源 报错 “PackagesNotFoundError”，然后开梯子使用pip下载

注意，想要在conda虚拟环境目录下使用pip下载包，需要参照以下文章：

使用pip install替代conda install将packet下载到anaconda虚拟环境-优快云博客

类似于使用如下指令：

env_path\env_name\Scripts\pip.exe install gymnasium[all]

其中envpath可使用conda env list查看，env_name是个性化虚拟环境的名称

结果报了标题的错误，

“ERROR: Could not build wheels for box2d-py, which is required to install pyproject.toml-based projects”

接着使用

conda install pyproject

然后在别的博客中发现要下载这个：swig包

conda install swigCould not build wheels for box2d-py, which is required to install pyproject.toml-based projects - 知乎 (zhihu.com)

Could not build wheels for box2d-py, which is required to install pyproject.toml-based projects - 知乎 (zhihu.com)

下载了这两个包，发现仍然报错：

error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

然后根据报错进入该网址下载cpp-build-tools（记住别放C盘，然后不能存非空文件夹，可能还得解决缓存与根目录冲突），参考：解决安装强化学习库gymnasium，box2d安装报错的问题_error: could not build wheels for box2d-py, which -优快云博客

Microsoft C++ 生成工具 - Visual Studio

包缓存路径不能与共享的安装路径重叠_根安装路径不能与包缓存路径重叠-优快云博客

然后重新使用pip install gymnasium[all]

然后接着报错：

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
tables 3.8.0 requires blosc2~=2.0.0, which is not installed.

如下图

于是乎根据提示接着下载blosc2

然后重新使用pip下载gymnasium[all]

最后成功

开心~

最终我的倒立摆也跑起来了
