具体是这样的，今天下午我运行了一下 pip install --upgrade pyright，把 pyright 从 1.1.275 更新到了 1.1.278。
然后打开 .py 文件发现 lsp 迟迟不能就绪。
查看进程管理发现竟然有个进程的名字叫做 npm install [email protected]：
查看 *lsp-bridge* 缓冲发现出错了：

为何 pyright/langserver.py 会启动安装命令？我好奇打开看了一下。顿时明白了，pip 安装的只不过是个“安装脚本”，而且里面有坑：
def run(
*args: str,
**kwargs: Any,
) -> Union['subprocess.CompletedProcess[bytes]', 'subprocess.CompletedProcess[str]']:
TEMP_DIR.mkdir(exist_ok=True, parents=True)
version = os.environ.get('PYRIGHT_PYTHON_FORCE_VERSION')
if version is None:
version = node.latest('pyright')
pkg = TEMP_DIR / 'node_modules' / 'pyright' / 'package.json'
if pkg.exists():
current_version = json.loads(pkg.read_text()).get('version')
else:
current_version = None
# TODO: use the same install location as the pyright CLI
if current_version is None or current_version != version:
node.run('npm', 'install', f'pyright@{version}', cwd=str(TEMP_DIR), check=True)
binary = TEMP_DIR / 'node_modules' / 'pyright' / 'langserver.index.js'
if not binary.exists():
raise RuntimeError(f'Expected language server entrypoint: {binary} to exist')
return node.run('node', str(binary), '--', *args, **kwargs)
- pip 和 npm 仓库更新不同步，前者停留在 1.1.278，而后者更新到了 1.1.279.
- 每次开启 pyright 时，就发现两个版本不匹配（哪怕比较一下版本大小也好啊），然后安装新版本。（但不知为何出错了）
- (手动更新 pyright 成功，) 重新加载走到第 2 步骤还是不匹配。
上边的源代码里还“贴心”地准备了一个环境变量，让用户可以手动解除窘境：PYRIGHT_PYTHON_FORCE_VERSION。当然也可以直接屏蔽更新语句。
从 pip 安装也是看了 pyright 官方说明。他们难道不知道自己在挖坑吗？明明 npm 就可以安装。
刚刚 pip 和 npm 版本终于同步上了：(注意截图中的时间)
