[英]lxml will never finish building on ubuntu
I am running ubuntu 14.04 LTS and python 2.7.5 on a vwmare.我在 vwmare 上运行 ubuntu 14.04 LTS 和 python 2.7.5。
When I run:当我运行时:
sudo pip install lxml
I get:我得到:
Collecting lxml
Using cached lxml-3.4.4.tar.gz
Building wheels for collected packages: lxml
Running setup.py bdist_wheel for lxml
which runs eternally.永远运行。
I can't find any resources related to this, nor do I have any experience with similar errors.我找不到与此相关的任何资源,也没有任何类似错误的经验。
Note, the solution below does not work:请注意,以下解决方案不起作用:
sudo apt-get build-dep -y lxml;
pip install lxml
I have also tried:我也试过:
sudo apt-get install -y build-essential python-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
build-essential is already the newest version.
python-dev is already the newest version.

If you're building on a VM or SBC with limited resources this can take a while...如果您在资源有限的 VM 或 SBC 上构建,这可能需要一段时间......
I ran this on VM with 768MB ram (which i didn't notice was the value i set) and it took several hours and didn't finish.我在具有 768MB ram 的 VM 上运行此程序(我没有注意到这是我设置的值),并且花了几个小时并没有完成。
Changing ram to 3GB made it finish in few minutes after restarting and trying again.将 ram 更改为 3GB 使其在重新启动并重试后几分钟内完成。
I ran into the same problem when trying to "pip install" a package that depends on lxml on a Raspberry Pi 1 B+.我在尝试“pip install”一个依赖于 Raspberry Pi 1 B+ 上的 lxml 的包时遇到了同样的问题。 After several hours (and several attempts), the SSH connection dropped without finishing the wheel build.
几个小时(和几次尝试)后,SSH 连接在没有完成轮子构建的情况下就断开了。 It seems like an out-of-memory situation.
这似乎是内存不足的情况。
I opted on installing the pre-built binary packages using apt install python-lxml
or apt install python3-lxml
respectively.我选择分别使用
apt install python-lxml
或apt install python3-lxml
安装预先构建的二进制包。
The newest version of pip, unnecessarily spends excessive amount of time to build wheels and resolve dependency issues while building a package with requirements.txt or a setuptools/distutils setup.py最新版本的 pip,在使用 requirements.txt 或 setuptools/distutils setup.py 构建包时,不必要地花费过多时间来构建轮子并解决依赖问题
A quick fix is to revert to a version of pip prior to 21.0 (ideally in a virtual environment), where the legacy resolver is still supported, according to this discussion:sunsetting legacy resolver根据此讨论,快速修复是恢复到 21.0 之前的 pip 版本(理想情况下在虚拟环境中),其中仍然支持旧式解析器:suntingting legacy resolver
As of July 28th, 2021 pip v21.2.1 still seems to have the legacy resolver support.截至 2021 年 7 月 28 日,pip v21.2.1 似乎仍然支持旧版解析器。
pip install pip==20.2.4
Command below uses an earlier version of dependency resolver to install lxml.下面的命令使用早期版本的依赖解析器来安装 lxml。
pip install --use-deprecated=legacy-resolver lxml
Saved me a lot of time and hassle.为我节省了很多时间和麻烦。
I think you should to install cython.我认为你应该安装cython。 As I can see in your code it is said that:
Building without Cython.
正如我在您的代码中看到的那样:在
Building without Cython.
and if we go to pypi and look up for lxml it is said that Note that this requires Cython to build the sources, see the build instructions on the project home page.如果我们去 pypi 并查找 lxml 据说注意这需要 Cython 来构建源代码,请参阅项目主页上的构建说明。 Here is the link: lxml
