一、pyenv安装python,出现以下错误：BUILD FAILED (Ubuntu 20.04 using python-build 2.3.36-21-g7e550e31) Inspect or clean up the working tree at /tmp/python-build.20240326131817.1499499 Results logged to /tmp/python-build.20240326131817.1499499.log Last 10 log lines: File "/tmp/python-build.20240326131817.1499499/Python-3.10.14/Lib/ensurepip/__ return bootstrap( File "/tmp/python-build.20240326131817.1499499/Python-3.10.14/Lib/ensurepip/_ return run_pip([*args, *PACKAGE_NAMES], additional_paths) File "/tmp/python-build.20240326131817.1499499/Python-3.10.14/Lib/ensurepip/ return subprocess.run(cmd, check=True).returncode File "/tmp/python-build.20240326131817.1499499/Python-3.10.14/Lib/subprocess.p raise CalledProcessError(retcode, process.args, subprocess.CalledProcessError: Command '['/tmp/python-build.20240326131817.14994ny.whl\', \'/tmp/tmpb4h_j2fk/pip-23.0.1-py3-none-any.whl\'] + sys.path\nsys.argvrunpy.run_module("pip", run_name="main", alter_sys=True)\n']' returned non-z make: *** [Makefile:1280: install] Error 1

清理构建目录 ：删除 /tmp/目录下的所有 python-build.开头的文件，可能会有助于解决这个问题。这将清除之前的构建尝试，并允许 pyenv 重新开始构建过程。
确保构建依赖项安装 ：重新安装以下库，如 build-essential、libssl-dev、zlib1g-dev、libbz2-dev、libreadline-dev、libsqlite3-dev、wget、curl 等。

二、pyenv安装python,出现以下错误：Traceback (most recent call last): File "<string>", line 1, in <module> File "/home/xtjie/.pyenv/versions/3.10.14/lib/python3.10/lzma.py", line 27, in <module> from _lzma import * ModuleNotFoundError: No module named '_lzma' WARNING: The Python lzma extension was not compiled. Missing the lzma lib? Installed Python-3.10.14 to /home/xtjie/.pyenv/versions/3.10.14

安装 liblzma-dev 包，这是开发版本的 lzma 库，包含了编译 _lzma 模块所需的头文件。
复制代码
```
sudo apt-get update sudo apt-get install -y liblzma-dev
```
重新编译 Python。如果你之前已经使用 pyenv 安装了 Python，你需要先删除旧的版本，然后再重新安装：
复制代码
```
pyenv uninstall 3.10.14 pyenv install 3.10.14
```

以上参考kimi大模型解决。
