Question

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

我正在处理此本地副本，因为我没有在计算机上拥有root或sudo权限。

要安装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

已创建的

/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

然而，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)

我认为这是因为PyYAML在默认位置寻找libyaml。是否需要为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中为我工作

然后我提取它并在打开后我在这个位置写了命令setup.py install

其他包在https://pypi.python.org/simple

中搜索

根据答案here的想法，这些步骤对我有用

<style>

然后在您的脚本中替换

pip install --user ruamel.yaml

使用：

import yaml

在没有root或sudo的情况下安装PyYAML和libyaml
