I finally resorted to using conda to set up an environment rather than virtualenv. Apparently virtualenv is not compatible with anaconda.

我最终求助于使用 conda 来设置环境而不是 virtualenv。显然 virtualenv 与 anaconda 不兼容。

Info in this link helped me set it up:

I tried for hours, read lots of posts and finally find a way out.

我尝试了几个小时，阅读了很多帖子，终于找到了出路。

pip uninstall virtualenv conda install virtualenv

pip uninstall virtualenv conda install virtualenv

The reason is the virtualenv installed by pip is not compatible with conda. I don't know more details, but it works for me.

原因是pip安装的virtualenv与conda不兼容。我不知道更多细节，但它对我有用。

I got this error while having several python versions installed on my mac. Specifying which python version to be used for your new virtual environment solves the issue.

在我的 mac 上安装了多个 python 版本时出现此错误。指定用于新虚拟环境的 Python 版本可以解决该问题。

By specifying the absolute python path:

通过指定绝对python路径：

virtualenv -p /usr/bin/python2.7 venv

or use your default python link:

或使用您的默认 python 链接：

virtualenv -p python3 venv

I had this same issue while installing requirements from requirements.txt.

从requirements.txt.

This was what solved the problem for me.

这就是为我解决问题的原因。

1. pip install --upgrade virtualenv

2. pip install --upgrade pip

3. After doing this, if you ever get errors while trying to install a dependency like below

1. pip install --upgrade virtualenv

2. pip install --upgrade pip

3. 执行此操作后，如果您在尝试安装如下依赖项时遇到错误

Otherwise, examine the package contents carefully; someone may have tampered with them. pbr==3.1.1 from https://pypi.python.org/packages/0c/5d/b077dbf309993d52c1d71e6bf6fe443a8029ea215135ebbe0b1b10e7aefc/pbr-3.1.1-py2.py3-none-any.whl#md5=75a0f55856bfc9220af0d01244afec43(from -r requirements-test.txt (line 52)):

Then use pip --no-cache-dir install <package-name>to install the package; where <package-name>is the name of the package you want to install.

然后使用pip --no-cache-dir install <package-name>安装包；<package-name>您要安装的软件包的名称在哪里。

e.g pip --no-cache-dir install pbr

例如 pip --no-cache-dir install pbr

Running

跑步

conda install -c anaconda virtualenv=15.1.0 

worked for me.

为我工作。

This is because virtualenv doesnt work with pip while conda exists on your system.

这是因为当您的系统上存在 conda 时，virtualenv 不适用于 pip。

I had the same error even with no anaconda installed. After a few minutes i realized that i was trying to create a virtualenv folder (C:/myname/virtual_folder) at the same directory levelas was my Python installation folder (C:/myname/python27) .

即使没有安装anaconda，我也遇到了同样的错误。几分钟后，我意识到我正在尝试在与Python 安装文件夹 (C:/myname/python27)相同的目录级别创建一个 virtualenv 文件夹 (C:/myname/virtual_folder )。

So I just created a folder and then inside of it (C:/myname/prefolder/..) i run ("virtualenv virtual_folder") with no issues .

所以我只是创建了一个文件夹，然后在它里面 (C:/myname/prefolder/..) 我运行 ("virtualenv virtual_folder") 没有问题。

You can save yourself from all this hustle by just downloading latest version of python, install it before you begin openstack or devstack installation. Go to https://www.python.org/downloads/. Installing latest version of python will replace the older version and install all the libraries you need. This saved me four days of trying to install devstack

您只需下载最新版本的 python，在开始安装 openstack 或 devstack 之前安装它，就可以避免所有这些麻烦。转到https://www.python.org/downloads/。安装最新版本的 python 将替换旧版本并安装您需要的所有库。这为我节省了四天尝试安装 devstack 的时间

For 3.7.3, i did a pip install --upgrade pip (from 18.1 to 19.1)

对于 3.7.3，我做了一个 pip install --upgrade pip（从 18.1 到 19.1）

Then i did the required installation and it worked (for pyinstaller)

然后我做了所需的安装并且它工作了（对于pyinstaller）

I have the same problem. The reason was with invalid path of python. Fixed it with removing python to 'c:\python37' from appdata. It cuz you have unicode chars in the path name.

我也有同样的问题。原因是python的路径无效。通过从 appdata 中删除 python 到 'c:\python37' 来修复它。因为你的路径名中有 unicode 字符。
