Question

我不确定这是因为我在公司工作并且有代理，我无法设置环境变量。所以，我不能在CMD中使用pip install。我尝试将软件包下载到我的本地计算机，并使用Installing python module within code中的方法进行安装。但我失败了。这是我的代码：

import pip
pip.main(['install','h://feng.officeworks/mixed/myPython/numpy-1.12.0'])

这对我不起作用，我有以下信息：

Invalid requirement: 'h://feng.officeworks/mixed/myPython/numpy'

我使用的是Windows 10，Python 3.6.0，Pycharm 2016.3.2。 pip已经安装了Python

另外，因为我无法访问环境变量，所以无法设置Python的路径。所以我不能在窗口终端中使用像python或pip这样的命令。所以我需要在python控制台中使用一个函数。

非常感谢你的回答。我还试着去C：\ Users \ fchen4 \ AppData \ Local \ Programs \ Python \ Python36-32 \ Scripts，然后使用

pip install h://mypath/numpy.

我已经在这里解开numpy了。这是行不通的。 PowerShell中显示的信息如下：

任何人都可以告诉我如何在python控制台中使用pip或其他任何东西安装本地软件包？

Answer 1

安装特定的源存档文件：

pip install ./downloads/SomePackage-1.0.4.tar.gz

您也可以下载模块源代码并安装它，将存档解压缩到名称相同的目录：foo-1.0。此外，分发将包含安装脚本setup.py，然后从终端运行此命令：

python setup.py install

如果您想在代码中安装软件包，请尝试以下方法：

import os
os.system("pip2.7 install foo")

或

import subprocess
subprocess.call(['pip', 'install', foo])

希望这有帮助。
