我正在使用一个 repo，它有一个包含 lxml==3.8.0 的 requirements.txt 文件，但我们从未真正使用过它，并且当我尝试安装需求文件时它会导致错误。所以我从 requirements.txt 中删除了 lxml 并尝试安装它仍然尝试安装它。我也尝试使用 pipenv install 代替，同样没有 lxml，它也尝试安装 lxml。我搜索了整个 repo，并且 requirements.txt 文件是唯一有 lxml 的地方，所以我不认为它藏在某个地方。 pip install 列出了 126 个依赖项，但文件中只有 125 个。我还尝试使用新的拉力创建一个新环境，以防该环境中有一些奇怪的东西。我也尝试过单独安装 lxml 并且安装正常，但是安装后安装需求或 pip 文件仍然会失败。这是唯一一个失败的安装，这里没有其他人知道 python 或如何使用这个 repo...

所以 lxml 显示在那里，但是如果它不在任何文件中并且它不是依赖项的依赖项，它来自哪里？我运行 pipenv uninstall lxml 并收到消息“没有要从 Pipfile 中删除的包 lxml”。并重新检查了这棵树，它仍然在那里。
还跑了： sudo apt-get --purge 删除 lxml 阅读包裹清单...完成 构建依赖树 读取状态信息...完成 E: 无法定位包 lxml
编辑：看起来 lxml 被添加到 pipfile.lock 中，即使它不在 pipfile 中。所以这很整洁。我从锁定文件中删除，一切正常，但还是很高兴知道为什么会发生这种情况。
答案 0 :(得分：0)
最有可能的附加依赖项是您的 requirements.txt 中指定的某些依赖项的传递依赖项
您可以使用 pipdeptree
pipdeptree -f | tee locked-requirements.txt
