创建 virtualenv 错误消息

金字塔文档说：

“最佳实践是将 Pyramid 安装到‘虚拟’Python 环境中，以便与您在 Python 版本中安装的任何‘系统’软件包隔离”
来安装虚拟 Python 环境，我有要安装 setuptools，它可以
创建一个虚拟 Python 环境，我必须
在说出命令后运行“virtualenv --no-site-packages env”，它说“如果您在 UNIX 上，请勿使用 sudo 运行virtualenv script”

3 日，我运行了该命令，但权限被拒绝并使用了 sudo。我不知道使用 sudo 部分是否会出现问题，因为我不确定 Linux 是否是一种 Unix。

现在，看到这条消息后如何创建虚拟Python环境？

Traceback (most recent call last):

    load_entry_point('virtualenv==1.5.1', 'console_scripts', 'virtualenv')()

The pyramid documentation says:

"It is best practice to install Pyramid into a 'virtual' Python environment in order to obtain isolation from any 'system' packages you’ve got installed in your Python version"
to install a Virtual Python Enviroment, I have to install setuptools, it worked
to create a Virtual Python Enviroment, I have to run "virtualenv --no-site-packages env"
after saying the command, it says "If you’re on UNIX, do not use sudo to run the virtualenv script"

On 3, I ran the command, got permission denied and used sudo. I don't know if the using sudo part is going to be a problem, because I'm not sure if Linux is a kind of Unix.

Now, how to create a virtual python enviroment after seeing this message?

确保您位于可以在其中创建文件和文件夹的目录，例如：

cd # Go to your home directory
virtualenv --no-site-packages env # Create virtualenv

Make sure you are in a directory that you can create files and folders in, e.g.:

cd # Go to your home directory
virtualenv --no-site-packages env # Create virtualenv

正如有人已经说过的，您需要在不使用 sudo 的情况下启动 virtualenv。

这对我有用。

安装setuptools并运行“virtualenv --no-site-package”后，您实际上并没有安装virtualenv，

因此首先您必须安装virtualenv（您必须是root用户）：

$ easy_install virtualenv

然后只需执行以下操作：

$ virtualenv --no-site-package myVirtualEnv
    New python executable in myVirtualEnv/bin/python
    Installing setuptools............done.

linux也是一个类似unix的系统（以回答您的问题）问题“Linux 是否是一种 Unix”）。
在这里您可以找到有关类 Unix 系统的更多信息 - wikipedia-Unix-like

after installing setuptools and running "virtualenv --no-site-package" you didnt actually install virtualenv

so first you must install virtualenv (you must be root for this):

$ easy_install virtualenv

then just do:

$ virtualenv --no-site-package myVirtualEnv
    New python executable in myVirtualEnv/bin/python
    Installing setuptools............done.

also linux is a unix like system (to answer your question if "Linux is a kind of Unix").
here you will find out more about unix-like systems - wikipedia-Unix-like
