【Python入门】37.常用第三方模块之 创建虚拟环境virtualenv

摘要：virtualenv可创建独立的虚拟运行环境，解决了不同应用项目间多版本的不兼容问题。

常用第三方模块

  • virtualenv

virtualenv

安装virtualenv

在命令行模式下输入：

等待安装成功即可。

创建虚拟环境

首先通过cd命令进入需要创建虚拟环境的文件目录，如在D盘的envs文件夹里面：

然后通过 virtualenv 创建一个虚拟环境，我们将它命名为 new_env

然后会看到下面结果：

说明成功使用当前系统的Python版本创建了一个虚拟环境。

使用virtualenv

通过cd命令进入虚拟环境目录下的Scripts目录：

然后输入 activate

会出现下面的结果：

地址前面的括号表示，当前环境是Python创建的虚拟环境 new_env 。

输入python，可查看当前环境的Python版本。 输入pip list，可查看当前环境下包含的库的版本。 在虚拟环境下，用pip安装的所有包都会装在new_env环境下，系统Python环境不受影响。这样，我们就可以安装运行项目所需要的工具版本了。 最后，使用deactivate命令退出虚拟环境。 virtualenv可创建独立的虚拟运行环境，解决了不同应用项目间多版本的不兼容问题。 以上就是本节的全部内容，感谢你的阅读。 下一节内容：图形界面 有任何问题与想法，欢迎评论与吐槽。 和博主一起学习Python吧(￣▽￣)~*

关于python第三方模块 求指教

你先从python的安装开始检查，或者重装python； 安装的时候在第一个页面把 □add path勾上，默认添加环境变量，可能是你没有添加。 安装的时候尽量用国内的镜像源，可以先升级pip指令，然后要切换到安装python的目录下，我这边是安装在C盘的根目录所以写 cd c:\ 回车后加上指令。

  1. python -m pip install --upgrade pip -i --trusted-host pypi.douban.com
  2. 切换为C盘根目录：pip install -i pillow
cd c:\ pip install -i   pillow

看看你编写代码的工具里面有没有导入库，如果还不行就是你工具的原因。 工具你可以使用wing pro，vscode，aptana 三选一，体量小，方便使用。 还有不懂你再追问。

怎么安装python 第三方模块

方法1：下载源码，手动运行setup.py install去安装。下载对应的源码，往往都是tar.gz，zip的压缩包，解压后，打开windows的cmd，切换到对应目录，运行：

setup.py install

即可去安装。 方法2：利用第三方安装工具（如pip，easy_install，distr）

python 第三方库怎么安装

【方法一】: 通过setuptools来安装python模块

首先下载 NOTE: 最好下载个setuptools，本人是15.2版本，里面包含了ez_setup 运行：

python ez_setup.py

输出示例：

D:\work\installation\setuptools-15.2\setuptools-15.2python ez_setup.py 1.txt
Extracting in c:\users\admini~1\appdata\local\temp\tmpbxikxf
Now working in c:\users\admini~1\appdata\local\temp\tmpbxikxf\setuptools-15.2
Installing Setuptools
......
Copying setuptools-15.2-py2.7.egg to c:\python27\lib\site-packages
setuptools 15.2 is already the active version in easy-install.pth
Installing easy_install-script.py script to C:\Python27\Scripts
Installing easy_install.exe script to C:\Python27\Scripts
Installing easy_install-2.7-script.py script to C:\Python27\Scripts

Installed c:\python27\lib\site-packages\setuptools-15.2-py2.7.egg
Processing dependencies for setuptools==15.2
Finished processing dependencies for setuptools==15.2

运行：

easy_install py

输出示例：

D:\workeasy_install py #py 为第三方库文件
Searching for py
Best match: py 1.4.26
Adding py 1.4.26 to easy-install.pth file
Using c:\python27\lib\site-packages

【方法二】: 通过pip来安装python模块

安装：

easy_install pip

输出示例：

D:\workeasy_install pip
Searching for pip
Best match: pip 6.1.1
Processing pip-6.1.1-py2.7.egg
pip 6.1.1 is already the active version in easy-install.pth
Installing pip-script.py script to C:\Python27\Scripts
Installing pip.exe script to C:\Python27\Scripts
Installing pip2.7-script.py script to C:\Python27\Scripts
Installing pip2.7.exe script to C:\Python27\Scripts
Installing pip2-script.py script to C:\Python27\Scripts
Installing pip2.exe script to C:\Python27\Scripts
Using c:\python27\lib\site-packages\pip-6.1.1-py2.7.egg
Processing dependencies for pip
Finished processing dependencies for pip

运行：

pip install xlrd

Usage:

pip command [options]

Commands:

  • install Install packages.
  • uninstall Uninstall packages.
  • freeze Output installed packages in requirements format.
  • list List installed packages.
  • show Show information about installed packages.
  • search Search PyPI for packages.
  • wheel Build wheels from your requirements.
  • zip DEPRECATED. Zip individual packages.
  • unzip DEPRECATED. Unzip individual packages.
  • help Show help for commands. General Options:
  • -h, --help Show help.
  • --isolated Run pip in an isolated mode, ignoring environment variables and user configuration.
  • -v, --verbose Give more output. Option is additive, and can be used up to 3 times.
  • -V, --version Show version and exit.
  • -q, --quiet Give less output.
  • --log path Path to a verbose appending log.
  • --proxy proxy Specify a proxy in the form [user:passwd@]proxy.server:port.
  • --retries retries Maximum number of retries each connection should attempt (default 5 times).
  • --timeout sec Set the socket timeout (default 15 seconds).
  • --exists-action action Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup.
  • --trusted-host hostname Mark this host as trusted, even though it does not have valid or any HTTPS.
  • --cert path Path to alternate CA bundle.
  • --client-cert path Path to SSL client certificate, a single file containing the private key and the certificate in PEM format.
  • --cache-dir dir Store the cache data in dir.
  • --no-cache-dir Disable the cache.
  • --disable-pip-version-check Don't periodically check PyPI to determine whether a new version of pip is available for download. Implied with --no-index.

【方法三】:直接从网上下载下可执行文件来安装.

比如说，去 pythonlibs 网站，提供了很多Python非官方包下载，二进制文件，下载安装方便.
