Question

安装了juju的所有依赖项

pip install pyparsing==1.5.7
pip install pyOpenSSL PyYAML txaws pydot oauth txzookeeper zc-zookeeper-static
pip install juju

所有安装正常，但是当我启动juju时，失败并出现以下错误：

(jujuapp) ± juju

    from yaml import CSafeLoader, CSafeDumper, Mark
ImportError: cannot import name CSafeLoader

这是什么错误？我通过自制软件安装Mac 10.6，python和pip。

我刚刚在10.8遇到了这个问题; juju在PyYaml中使用了libyaml绑定，因此它需要安装PyYaml --with-libyaml，这需要比mac上的更多。以下是我如何运作：

brew install libyaml with homebrew
下载PyYaml源代码（instructions）

现在像这样修改[pyyaml-install-dir]/setup.cfg：

# List of directories to search for 'yaml.h' (separated by ':').
include_dirs=/usr/local/Cellar/libyaml/0.1.4/include/

# List of directories to search for 'libyaml.a' (separated by ':').
library_dirs=/usr/local/Cellar/libyaml/0.1.4/lib/

所以它可以找到你自制的libyaml安装。然后您还需要安装Cython ..

sudo pip install cython

最后..

sudo python setup.py --with-libyaml install（在PyYaml目录中）

现在juju应该工作了！
