如何使用 pip 安装 pyinstaller

Question

我正在尝试使用 pip 安装 PyInstaller，但我没有这样做。我有 Python 2.7。

错误：

C:\Python27\Scripts>pip install pyinstaller
Downloading/unpacking pyinstaller
Cannot fetch index base URL http://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement pyinstaller
No distributions at all found for pyinstaller
Storing complete log in C:\Users\hardik\AppData\Roaming\pip\pip.log

我尝试先使用pip install -U pip setuptools 升级 pip，但遇到了同样的错误：

C:\Users\hardik>pip install -U pip setuptools
Cannot fetch index base URL pypi.python.org/simple
Could not find any downloads that satisfy the requirement pip in c:\python27\lib \site-packages
No distributions at all found for pip in c:\python27\lib\site-packages
