无法安装Python库（python无法安装库怎么办）

我无法安装任何Python库。我正在使用pip 9.0.1和python 2.7。我收到以下错误：

EN-NishantS:~ 8417$ pip install presto-python-clientCollecting presto-python-client  Could not find a version that satisfies the requirement presto-python-client (from versions: )No matching distribution found for presto-python-client

与pip install -vvv我一起跑步时，我得到以下信息：

centOS5安装python库的问题!

centOS5安装python库的问题!

centOS5的yum用的python2.4
而生产环境需要python2.7, 于是再装一个python2.7, 程序需要用到libxml2, 这个库需要使用yum来安装, 但是安装之后py文件跑到python2.4的site-packages里去了, python2.7里显然调用不了, 也试过下载源码进行编译安装, 但是也不行, 想知道这种情况应该怎么解决, 谢谢!

linux – 无法安装python-igraph

我正在尝试安装 python-igraph.我运行sudo pip后运行python-igraph我得到了以下日志：

如果我使用sudo python setup.py install,我也有类似的情况.

显然问题在于C核心.

如何安装正确的版本以便我可以安装igraph？

我使用Linux Mint 16 64位,python 2.7.

解决方法

在编译python-igraph之前,你需要igraph库.

尝试sudo apt-get install -y libigraph0-dev并再次尝试安装python-igraph.

pip 只能安装python库吗

pip 只能安装python库吗

pip 是 python 包管理工具，该工具提供了对python 包的查找、下载、安装、卸载的功能。目前如果你在 python.org 下载最新版本的安装包，则是已经自带了该工具。

Python 2.7.9 + 或 Python 3.4+ 以上版本都自带 pip 工具。

pip 只能安装python库吗

pip 官网：https://pypi.org/project/pip/

你可以通过以下命令来判断是否已安装：

立即学习“Python免费学习笔记（深入）”；

pip --version
登录后复制

如果你还未安装，则可以使用以下方法来安装：

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py   # 下载安装脚本
$ sudo python get-pip.py    # 运行安装脚本
登录后复制

注意：用哪个版本的 Python 运行安装脚本，pip 就被关联到哪个版本，如果是 Python3 则执行以下命令：

$ sudo python3 get-pip.py    # 运行安装脚本。
登录后复制

一般情况 pip 对应的是 Python 2.7，pip3 对应的是 Python 3.x。

部分 Linux 发行版可直接用包管理器安装 pip，如 Debian 和 Ubuntu：

sudo apt-get install python-pip
登录后复制

以上就是pip 只能安装python库吗的详细内容，更多请关注php中文网其它相关文章！

Python 无法安装py2app

Python 无法安装py2app

因为需要给mac程序打包应用，需要安装py2app

正常安装pip install py2app,结果报错
