lxml 没有安装在带有 Python 3.4.3 的 Amazon Linux 64 位上。

Question

注意：重复的帖子并没有解决我的问题。

我正在将 Python 3.4 用于 Amazon EC2 实例（运行 Python 3.4 的 64 位 Amazon Linux 2016.09 v2.2.0）上基于 Flask 的应用程序。

部署 lxml 时未安装。错误日志是：

我已经完成了 百胜安装 libxslt-devel libxml2-devel 百胜安装gcc

安装python34-lxml 或python3-lxml 显示这些包不可用。 我还尝试使用yum 安装python-lxml，但显示No package python-lxml available

为了安装 lxml，我使用 SSH 连接到 EC2 实例并执行了sudo pip install lxml，但它也被终止了。

我最终通过使用 SSH 连接到 EC2 实例，使用 sudo CFLAGS="-O0" pip install lxml 安装了 lxml。 我已经安装了依赖libxslt-devel libxml2-devel gcc

问题仍然存在，并且 ElasticBeanstalk 显示上述日志。

问题是由于 RAM 大小造成的。

我增加了 RAM，然后尝试安装它，它成功了。

如果您遇到此问题，请为您的云应用安装更多 RAN。 lxml 在安装时会占用大量内存。
