I'm trying to follow How To Serve Django Applications with uWSGI and Nginx on Ubuntu 14.04and I'm failing at the very earlier stage, due to amount of output, I placed all related information into Pastebin.com - #1 paste tool since 2002!.

我正在尝试遵循如何在 Ubuntu 14.04 上使用 uWSGI 和 Nginx 为 Django 应用程序提供服务，但由于输出量太大，我在很早的阶段失败了，我将所有相关信息放入Pastebin.com - #1 粘贴工具，因为2002！.

the actual error:

实际错误：

root@alexus:~# echo "source /usr/local/bin/virtualenvwrapper.sh" >> ~/.bashrc

/usr/bin/python3: Error while finding spec for 'virtualenvwrapper.hook_loader' (<class 'ImportError'>: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 and that PATH is
set properly.

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python

导出 VIRTUALENVWRAPPER_PYTHON=/usr/bin/python

good choice, but you already knew /usr/bin/python is 2.7

不错的选择，但您已经知道 /usr/bin/python 是 2.7

If you want to use version 3

I faced similar problem, when using python3 with virtualenvwrapper,

我遇到了类似的问题，当使用 python3 和 virtualenvwrapper 时，

sudo apt-get install python3-pip

Then install virtualenv and virtualenvwrapper from pip3,

然后从pip3安装virtualenv和virtualenvwrapper，

sudo pip3 install virtualenv virtualenvwrapper

then source it again,

然后再次来源，

source $HOME/.bashrc

I encountered a similar issue with virtualenvwrappercomplaining not being to find virtualenvwrapper.hook_loader. I was able to narrow down to this particular line in my .bash_profile

我遇到了类似的问题，virtualenvwrapper抱怨没有找到virtualenvwrapper.hook_loader. 我能够缩小到我的这一特定行.bash_profile

source /usr/local/bin/virtualenvwrapper.sh

源/usr/local/bin/virtualenvwrapper.sh

as seen below

如下所示

$ source /usr/local/bin/virtualenvwrapper.sh
/usr/local/opt/python3/bin/python3.6: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks. 

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 and that PATH is
set properly.

After some trial and error, it turns out that a reinstallation of the virtualenvwrapperpackage resolved it. This was a manifest of the fact that I recently upgrade python3 (from version 3.5.2 to 3.6.1) via homebrew and in turn it broke virtualenvwrapper's shell script that hardcoded references to the older version of python3 (in my case it was 3.5.2). In short, this below line should fix it (at least in my case it did).

经过一些试验和错误，事实证明重新安装virtualenvwrapper软件包解决了它。这是我最近通过自制软件升级 python3（从 3.5.2 版到 3.6.1 版）这一事实的证明，反过来它破坏了 virtualenvwrapper 的 shell 脚本，该脚本对旧版本的 python3 的引用进行了硬编码（在我的情况下是 3.5。 2）。简而言之，下面这行应该修复它（至少在我的情况下是这样）。

pip3 install virtualenvwrapper

In macOS Sierra, If you installed virtualenvpackage using pip3, add following to .bash_profile

在 macOS Sierra 中，如果您virtualenv使用安装了软件包pip3，请将以下内容添加到.bash_profile

export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3

or

或者

export VIRTUALENVWRAPPER_PYTHON=$(which python3)

after that every new virtualenvironment you created using workon myvenvuses python3as python interpreter

以后您在使用创建的每个新的虚拟环境workon myvenv的用途python3为Python解释器

我已经安装了 virtualenv 所以只需要运行

回答by Evan Thomas

In my case, there was somehow a mismatch between pip3 and python3 (because I have multiple pythons installed). This worked for me:

就我而言，pip3 和 python3 之间存在某种不匹配（因为我安装了多个 python）。这对我有用：

sudo python -m pip install virtualenvwrapper

On my computer, I ran sudo apt install python-pipand then pip install virtualenvwrapperbut on my settings, I set it as follows:

在我的电脑上，我跑了sudo apt install python-pip然后pip install virtualenvwrapper但在我的设置中，我将其设置如下：

export WORKON_HOME=$HOME/.Envs
export VIRTUALENVWRAPPER_PYTHON=$(which -a python3)
source $HOME/.local/bin/virtualenvwrapper.sh

That got rid of the error and note that I am using python3 and I use pip3 as my default

这消除了错误并注意我使用的是 python3 并且我使用 pip3 作为我的默认值
