根据错误提示,这是一个UnicodeDecodeError错误,指定的字符串无法正确解码为ASCII字符集。可能是由于在字符串中使用了非ASCII字符,导致解码失败。您可以尝试使用Python的unicode()函数将字符串转换为Unicode格式,以避免此问题。您可以尝试使用以下命令:
su nova -s /bin/sh -c "nova-manage cell_v2 create_cell --name cell1 --verbose" 2>&1 | LC_ALL=C sed -n '1!p'
该命令将通过管道将错误输出重定向到sed命令。该sed命令将删除第一行并输出其余行,以便您可以更轻松地查看错误信息。

linux-gnu/bin/ld: cannot find -lib
This error message is indicating that the linker (ld) cannot find a library named "-lib". The linker is used to link together object files and libraries to create an executable file.
There could be several reasons why this error is occurring:
1. The library is not installed on the system: If the library is not installed on the system, the linker will not be able to find it. You can check if the library is installed by running the command "ldconfig -p | grep lib". This will show a list of all the libraries installed on the system.
2. The library is not in the linker's search path: The linker searches for libraries in certain directories. If the library is not in one of these directories, the linker will not be able to find it. You can check the linker's search path by running the command "ld --verbose | grep SEARCH_DIR". This will show a list of directories where the linker is searching for libraries.
3. The library is not named correctly: The linker is looking for a library named "-lib". This is not a valid library name. Library names should start with "lib" followed by the name of the library. For example, if the library is named "mylib", the linker should be looking for "libmylib.so" or "libmylib.a".
To fix this error, you will need to determine which of these issues is causing the problem and then take the appropriate action. If the library is not installed, you will need to install it. If the library is not in the linker's search path, you will need to add the directory containing the library to the linker's search path. If the library is not named correctly, you will need to rename it to start with "lib".

根据引用[1]中提供的信息,安装xgboost和lightGBM时出现了报错。这种报错通常是由于缺少依赖项或环境配置问题引起的。为了解决这个问题,可以尝试以下几种方法:
1. 确保已经安装了必要的依赖项。xgboost和lightGBM在安装过程中可能需要一些额外的依赖项。你可以查看官方文档或者安装指南来获取所需的依赖项列表,并确保这些依赖项已经正确安装。
2. 检查Python环境配置。在引用中提到,更换了Python环境后安装失败。这可能是由于新的Python环境缺少一些必要的配置或者路径设置不正确。你可以检查Python环境变量、路径和版本,确保它们与安装要求相匹配。
3. 更新pip和setuptools。有时候,旧版本的pip和setuptools可能会导致安装失败。你可以尝试更新它们到最新版本,然后再次尝试安装xgboost和lightGBM。
4. 使用虚拟环境。为了避免与其他Python包或环境冲突,你可以考虑在虚拟环境中安装xgboost和lightGBM。虚拟环境可以提供一个独立的Python环境,使得安装和配置更加简单和可靠。
5. 查找更详细的错误信息。在引用中提到了一个错误代码1,但没有提供更详细的错误信息。你可以尝试查找更多的错误信息,以便更好地理解问题所在。你可以尝试在安装命令中添加`--verbose`参数,或者查看相关日志文件来获取更多信息。
以下是一个示例代码,演示了如何使用虚拟环境来安装xgboost和lightGBM:
```shell
# 创建虚拟环境
python -m venv myenv
# 激活虚拟环境
source myenv/bin/activate
# 更新pip和setuptools
pip install --upgrade pip setuptools
# 安装xgboost和lightGBM
pip install xgboost lightgbm
# 安装成功后,可以在虚拟环境中使用xgboost和lightGBM
```
