无法使用"setuptools pip wheel failed with error code 1"创建虚拟环境

Question

我正在使用Windows 10和Python 3.5 64位.并从pip 安装virtualenv.

尝试创建新的虚拟环境时,它会因以下日志记录而失败:

  > virtualenv env1

使用--no-setuptools执行时,它运行良好并创建一个虚拟环境.

我遇到了类似但不同的错误，并且当前目录中有一个模块覆盖了 Python 的字符串模块。

这是我的堆栈跟踪。请注意，它基本上是说字符串模块没有属性maketrans。文档说事实并非如此。这是一个很大的暗示，表明字符串模块出了问题，这让我检查目录中是否有多余的模块。
