Python redis-log错误

Question

我正在尝试将我的 python 项目设置到我本地的 fedora 16 机器上。我已经使用 git 克隆了整个项目。

项目使用redis服务器。

输入命令后:python setup.py develop 我收到以下错误

Installed /usr/lib/python2.7/site-packages/python_redis_log-0.1.2-py2.7.egg
error: Could not find required distribution python-redis-log>=9999

我已经安装了redis 2.7

有人知道这里的问题是什么吗？非常感谢您的帮助。

问题是 setuptools 正在寻找至少具有指定版本号的所需包。 9999 大于 2.7.2，因此它会尝试下载 setup.py 文件中指定的版本。

install_requires 关键字的官方文档是 here

The simplest way to include requirement specifiers is to use the install_requires argument to setup(). It takes a string or list of strings containing requirement specifiers. If you include more than one requirement in a string, each requirement must begin on a new line.

此处描述了需求说明符:

setuptools and pkg_resources use a common syntax for specifying a project’s required dependencies. This syntax consists of a project’s PyPI name, optionally followed by a comma-separated list of “extras” in square brackets, optionally followed by a comma-separated list of version specifiers. A version specifier is one of the operators <, >, <=, >=, == or !=, followed by a version identifier. Tokens may be separated by whitespace, but any whitespace or nonstandard characters within a project name or version identifier must be replaced with -.

特别要解决您的问题:

你的setup.py文件有

install_requires = [ ...
                     'python-redis-log>=9999'

您拥有的版本说明符是 python-redis-log>=9999 ，因此您的项目要求 python-redis-log 的版本号为 9999 或更高。

如果将该行更改为

python-redis-log>=0.1.2

这应该可以解决问题。
