【问题描述】：

我需要使用 libyaml 绑定设置 PyYAML。我正在开发 5.7 版的 Red Hat Enterprise Linux 客户端，并且我在 /tools/Devel/epd_free-7.3-2rh5-x86_64 下安装了 Enthought Python 7.3.2 的本地副本并将/tools/Devel/epd_free-7.3-2rh5-x86_64/bin 添加到$PATH

我正在处理这个本地副本，因为我在机器上没有 root 或 sudo 访问权限。

安装 libyaml 我已经完成了：

tar -xvzf yaml-0.1.5.tar.gz
cd yaml-0.1.5
./configure prefix=/tools/Devel/epd_free-7.3-2-rh5-x86_64
make
make install

创造了

/tools/Devel/epd_free-7.3-2rh5-x86_64/include/yaml.h

还有

/tools/Devel/epd_free-7.3-2rh5-x86_64/lib/libyaml-0.so.2
/tools/Devel/epd_free-7.3-2rh5-x86_64/lib/libyaml-0.so.2.0.3
/tools/Devel/epd_free-7.3-2rh5-x86_64/lib/libyaml.a
/tools/Devel/epd_free-7.3-2rh5-x86_64/lib/libyaml.la
/tools/Devel/epd_free-7.3-2rh5-x86_64/lib/libyaml.so
/tools/Devel/epd_free-7.3-2rh5-x86_64/lib/pkgconfig

但是，当我尝试安装 PyYAML 时，我得到了

pip install PyYAML

    libyaml is not found or a compiler error: forcing --without-libyaml
    (if libyaml is installed correctly, you may need to
     specify the option --include-dirs or uncomment and
     modify the parameter include_dirs in setup.cfg)

Cleaning up...

我认为这是因为 PyYAML 在默认位置寻找 libyaml。是否可以为 pyyaml 安装指定 libyaml 的位置？

【解决方案1】：

使用https://pypi.python.org/simple/pyyaml/ 并下载 PyYAML-3.11.tar.gz 在 Windows 中为我工作

然后我解压它，打开后我在这个位置写了命令 setup.py install

其他包搜索https://pypi.python.org/simple

【解决方案2】：

基于答案here 的想法，这些步骤对我有用

pip install --user ruamel.yaml

然后在你的脚本中替换

import yaml

与：

from ruamel.yaml import YAML
yaml=YAML(typ='safe')
