pip 安装错误：ModuleNotFoundError 没有名为“setuptools”的模块答案

【问题标题】：pip install error: ModuleNotFoundError No module named 'setuptools'pip 安装错误：ModuleNotFoundError 没有名为“setuptools”的模块
【发布时间】：2017-08-26 01:13:17
【问题描述】：

当我在 PowerShell 控制台中运行 pip install virtualenvwrapper-win 时出现错误：

PS C:\Windows\system32> pip install virtualenvwrapper-win 采集 virtualenvwrapper-win 使用缓存的 virtualenvwrapper-win-1.2.1.zip 命令 python setup.py egg_info 的完整输出：回溯（最近一次通话最后）：文件“”，第 1 行，在 ModuleNotFoundError: 没有名为“setuptools”的模块

命令“python setup.py egg_info”失败，错误代码为 1

我尝试过pip install setuptools，也尝试过卸载并重新安装和更新，但错误仍然存在。

pip 和 python 可执行文件已添加到环境变量中。

【解决方案1】：

virtualenvwrapper-win 仅适用于 DOS cmd.exe。来自自述文件：

这些脚本应该适用于任何版本的 Windows（Windows XP、Windows Vista、Windows 7/8/10）。

但是，它们只能在常规命令提示符中工作。它们在 Powershell 中不起作用。还有其他适用于 Powershell 的 virtualenvwrapper 项目。

【解决方案2】：

尝试通过从此处下载 ZIP 存档手动安装 virtualenvwrapper-win 模块： https://pypi.python.org/pypi/virtualenvwrapper-win

在您的 PowerShell 控制台中，转到存档下载到的目录（我的目录是 C:\Users\user\Downloads\）并运行此命令以提取存档：Expand-Archive .\virtualenvwrapper-win-1.2.1.zip
仍在 PowerShell 中，在与上述相同的目录中，运行：cd .\virtualenvwrapper-win-1.2.1\virtualenvwrapper-win-1.2.1\
接下来，运行：python setup.py install

如果一切顺利，您应该会看到如下内容：
