请注意，我不是计算机人员，只是想通过键入以下内容来安装脚本：
pip install -r requirements.txt
然后这个错误在此过程中出现两次，我不知道为什么：
第一的 ：
Compile failed: command '/usr/bin/x86_64-linux-gnu-gcc' failed with exit code 1
creating tmp
cc -I/usr/include/libxml2 -I/usr/include/libxml2 -c /tmp/xmlXPathInitd5e8a29v.c -o tmp/xmlXPathInitd5e8a29v.o
cc tmp/xmlXPathInitd5e8a29v.o -lxml2 -o a.out
error: command '/usr/bin/x86_64-linux-gnu-gcc' failed with exit code 1
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for lxml

最后是这个：

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Can't roll back lxml; was not uninstalled

× Encountered error while trying to install package.
╰─> lxml
note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.
我认为这与编译器 gcc 或其他东西有关，因为我已经安装了 lxml。
我将非常感激您的帮助，并提前向您表示感谢。
