在BandwagonHost的虚拟主机上，使用pip3安装lxml时，遇到了如下问题：
pip3 install lxml
You are using pip version 6.0.8, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

通过google和错误日志得知，这是因为gcc在编译时由于内存不足，故被系统kill掉而导致的。此外由于Bandwagon Host采用的是OpenVZ，故无法手动增加swap。那么，在不更换主机的情况下，如何解决编译失败这个问题？
或者，假设本地有一台安装了和虚拟主机相同版本的centOS的电脑，那么能不能把在本地编译完成的文件上传到主机上使用？如果可以，那么需要对路径之类的配置文件做哪些改动？
假设本地有一台安装了和虚拟主机相同版本的 centOS 的电脑，下载 lxml 并解压，在解压目录下运行：
python setup.py bdist_wheel --static-deps
得到一个 whl 文件，上传后 pip install xxx.whl 即可。

去搜索你要安装的包是否有二进制版本
