### python相关软件更新(win10环境) ###

### pip安装升级: ###

### **一.  Pycharm(2019.2版本)虚拟环境的pip升级,** ###

*  尽量选择用cmd命令行下手动更新pip或其它软件包，而不要选择在pycharm的界面下直接用鼠标点升级,因为点击升级之后显示还是低版本.
 *  **解决办法**:需点开pycharm 底端的![20190908024941992.png][] Terminal窗口,运行python -m pip install --upgrade pip命令进行升级
 *  新版本中提示是用**python -m pip install -U pip **进行升级更新,注意字母 U是大写的.(不过写错运行会有提示**no such option: -u**)

###  **二.重新安装pip** ###

[curl使用指南][curl]

**在pycharm底部终端窗口Terminal升级pip出现错误**,不能升级,无外乎没有正常安装.重新安装pip即可.

**解决办法:**

右击[get-pip.py][]另存为本地,运行它即自动安装最新版本pip 下载[https://bootstrap.pypa.io/get-pip.py][get-pip.py]

**运行:**安装过pycharm的,双击下载之后.py文件,会自动打开。点击run菜单运行

或在win10 的cmd窗口中:**python get-pip.py**

> E:\\38016\\Downloads>**python get-pip.py**  
> Collecting pip  
>   Using cached https://files.pythonhosted.org/packages/……/pip-19.2.3-py2.py3-none-any.whl  
> Collecting wheel  
>   Using cached https://files.pythonhosted.org/packages/……/wheel-0.33.6-py2.py3-none-any.whl  
> Installing collected packages: pip, wheel  
>   Found existing installation: pip 19.2.3  
>     Uninstalling pip-19.2.3:  
>       Successfully uninstalled pip-19.2.3  
> **Successfully installed** pip-19.2.3 wheel-0.33.6
> 
> E:\\38016\\Downloads>

### 三、安装第三方库 ###

自行下载相关whl文件）

安装wheel:  
在cmd窗口运行如下语句

pip install wheel

在[http://www.lfd.uci.edu/~gohlke/pythonlibs/][http_www.lfd.uci.edu_gohlke_pythonlibs],往下滚动页面,找到并下载自己需要的whl文件并解压到Python/Lib/site-packages中。  
在cmd窗口运行  pip install 带.whl文件的路径

### 附学习参考: ###

### python安装包的官方说明:[https://packaging.python.org/tutorials/installing-packages/][https_packaging.python.org_tutorials_installing-packages] ###

# Quickstart ([https://pip.pypa.io/en/stable/quickstart/][https_pip.pypa.io_en_stable_quickstart])) #

First, [install pip][https_pip.pypa.io_en_stable_installing].

Install a package from [PyPI][]:

$ pip install SomePackage
    [...]
    Successfully installed SomePackage

Install a package that’s already been downloaded from [PyPI][] or obtained from elsewhere. This is useful if the target machine does not have a network connection:

$ pip install SomePackage-1.0-py2.py3-none-any.whl
    [...]
    Successfully installed SomePackage

Show what files were installed:

$ pip show --files SomePackage
    Name: SomePackage
    Version: 1.0
    Location: /my/env/lib/pythonx.x/site-packages
    Files:
      ../somepackage/__init__.py
      [...]

List what packages are outdated:

$ pip list --outdated
    SomePackage (Current: 1.0 Latest: 2.0)

Upgrade a package:

$ pip install --upgrade SomePackage
    [...]
    Found existing installation: SomePackage 1.0
    Uninstalling SomePackage:
      Successfully uninstalled SomePackage
    Running setup.py install for SomePackage
    Successfully installed SomePackage

Uninstall a package:

$ pip uninstall SomePackage
    Uninstalling SomePackage:
      /my/env/lib/pythonx.x/site-packages/somepackage
    Proceed (y/n)? y
    Successfully uninstalled SomePackage

## Upgrading pip ##

On Linux or macOS:

pip install -U pip

On Windows [4][]:

python -m pip install -U pip

[https://pypi.org/project/setuptools/][https_pypi.org_project_setuptools]

pip install setuptools

> D:\\Program Files\\python37\\scripts> **pip install setuptools**  
> **Requirement already satisfied:** setuptools in d:\\program files\\python37\\lib\\site-packages (40.8.0)
> 
> **在win10里删掉setuptools-40.8.0.dist-info文件夹之后:**  
> D:\\Program Files\\python37\\scripts> **pip install setuptools**  
> Collecting setuptools  
>   Using cached https://files.pythonhosted.org/packages/……/setuptools-41.2.0-py2.py3-none-any.whl  
> Installing collected packages: setuptools  
> **Successfully installed** setuptools-41.2.0  
> D:\\Program Files\\python37\\scripts>

### 似乎凡是遇到提示“Requirement already satisfied:”，都采取找到并删除与版本号有关的文件夹，然后再重新pip install ...都可以解决。 ###
