不带超级用户或sudo安装PyYAML和libyaml

Question

我需要用libyaml绑定设置PyYAML。我正在使用一个带有5.7版的Red Hat Enterprise Linux客户端，我在/tools/Devel/epd_free-7.3-2rh5-x86_64下安装了一个本地副本，并将/tools/Devel/epd_free-7.3-2rh5-x86_64/bin添加到了$PATH中

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。

要安装libyaml，我已经这样做了：

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

它已经创建了

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

以及

/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

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)

我认为这是因为PyYAML在缺省位置查找libyaml。有没有办法为pyyaml安装指定libyaml的位置？

Answer 1

使用https://pypi.python.org/simple/pyyaml/并下载PyYAML-3.11.tar.gz在windows中对我有效

然后我将其解压缩，并在打开后将命令setup.py install写入以下位置

有关其他软件包的信息，请在https://pypi.python.org/simple中搜索

Answer 2

基于答案here的想法，这些步骤对我很有效

pip install --user ruamel.yaml

然后在脚本中替换

import yaml

通过以下方式：

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