我正在使用一个repo，该repo有一个requirements.txt文件，其中包含lxml==3.8.0，但我们从未实际使用过它，而且在我尝试安装需求文件时，它会导致错误。因此，我从requirements.txt中删除了lxml，并尝试安装，但它仍然尝试安装它。我还尝试使用pipenv安装，同样没有lxml，它也尝试安装lxml。我已经搜索了整个repo，requirements.txt文件是唯一一个有lxml的地方，所以我不认为它隐藏在什么地方。pip安装列出了126个依赖项，但文件中只有125个。我还试着创造一个新的环境，以防环境中有什么奇怪的东西。我也尝试过自己安装lxml，它安装得很好，但安装后安装需求或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，但如果它不在任何文件中，并且不是依赖项的依赖项，它从哪里来？我运行了pipenvuninstall-lxml，得到了消息"；没有要从Pipfile中删除的包lxml"并重新检查了树，它仍然在那里。
还运行了：sudo apt-get—清除-删除lxml正在读取程序包列表。。。完成构建依赖关系树正在读取状态信息。。。完成E： 无法定位包lxml
编辑：看起来lxml被添加到了pipfile.lock中，尽管它不在pipfile中。所以这很巧妙。我从锁文件中删除了它，一切都正常了，但如果能知道为什么会发生这种情况，那就太好了。
大多数附加的可能是requirements.txt 中指定的某个依赖项的可传递依赖项
您可以使用pipdeptree
pipdeptree -f | tee locked-requirements.txt
