翻译 If the elements of a list are known beforehand, a quicker way to construct it is to call acutBuildList(), which takes a variable number of argument pairs (with exceptions such as RTLB, RTLE, -3, and others) and returns a pointer to a list of result buffers that contains the specified types and values, linked together in the order in which they were passed to acutBuildList(). This function allocates memory as required and initializes all values. The last argument to acutBuildList() must be a single argument whose value is either zero or RTNONE.

如果列表的元素在预先已知,构建它的更快方法是调用acutBuildList(),它接受可变数量的参数对(有一些例外,如RTLB、RTLE、-3和其他参数),并返回指向结果缓冲区列表的指针,该列表包含指定的类型和值,并按照它们传递给acutBuildList()的顺序链接在一起。该函数根据需要分配内存并初始化所有值。acutBuildList()的最后一个参数必须是单个参数,其值为零或RTNONE。

This error originates from a subprocess, and is likely not a problem with pip
This error message indicates that the error is not caused by pip itself, but rather by subprocess that pip is running. It suggests that the issue lies with the package being installed, not with pip.
To troubleshoot this error, you can try the following steps:
1. Check the error message: Look for any specific error messages or traceback information provided in the output. This can help identify the root cause of the issue.
2. Update pip: Make sure you have the latest version of pip installed. You can do this by running the following command:
```shell
pip install --upgrade pip
```
3. Check package compatibility: Verify that the package you are trying to install is compatible with your Python version and operating system. You can check the package documentation or the PyPI page for compatibility information.
4. Check dependencies: Some packages require certain dependencies to be installed beforehand. Make sure you have all the necessary dependencies installed before attempting to install the package.
5. Clean the pip cache: Sometimes, issues can arise due to a corrupted pip cache. You can try clearing the cache by running the following command:
```shell
pip cache purge
```
6. Use a virtual environment: Create a virtual environment and install the package within that environment. This can help isolate any conflicts with other packages or dependencies.
If the above steps do not resolve the issue, it is recommended to seek help from the package's community or the package maintainer for further assistance.
Could not build wheels for nes-py, which is required to install pyproject.toml-based projects
It seems that you are encountering an issue while trying to install a project that requires the "nes-py" library. The error message suggests that the installation process failed to build the required wheels for this library.
To resolve this issue, you can try the following steps:
1. Check if you have the necessary dependencies installed. Some libraries require certain system packages or development tools to be present before they can be built successfully. Make sure you have them installed beforehand.
2. Upgrade your pip and setuptools versions. Outdated versions of pip or setuptools can sometimes cause issues during the installation process. You can upgrade them by running the following command:
```
pip install --upgrade pip setuptools
```
3. Install the required system packages. Some libraries may require additional system packages or development tools to be installed. You can refer to the library's documentation or GitHub page for any specific requirements.
4. If you are trying to install the library in a virtual environment, ensure that you have activated the environment before installing. This will ensure that all dependencies are installed within the virtual environment itself.
5. If none of the above steps work, there might be an issue with the library itself. In such cases, you can try reaching out to the library's maintainers for further assistance or consider using an alternative library if available.
