EDIT :virtualenvwrapper.sh is written in bash, perhaps should I check my PATHinstead of my PYTHONPATH?

Thank you in advance for your help.

I finally found out what the problem was :

我终于发现了问题所在：

virtualenvwrapper.shis written in BASHand not in Python. So virtualenvis called from a shell (zsh). I didn't have to bother about my PYTHONPATH, but about my PATH(I was already able to import virtualenv from my python shell anyway).

virtualenvwrapper.sh是用BASH编写的，而不是用Python编写的。所以virtualenv是从 shell ( zsh)调用的。我不必担心我的PYTHONPATH，而是我的PATH（无论如何我已经能够从我的 python shell 中导入 virtualenv ）。

I just added the correct directory to my PATHand everything worked fine.

我刚刚将正确的目录添加到我的PATH 中，一切正常。

Your PYTHONPATH makes me think you have Homebrew installed. It sounds like virtualenvwrapper was installed with either your system pip or your homebrew pip while it is being executed with the opposite python interpreter.

你的 PYTHONPATH 让我觉得你安装了 Homebrew。听起来 virtualenvwrapper 是与您的系统 pip 或自制程序 pip 一起安装的，而它正在使用相反的 python 解释器执行。

1. sudo find / -name "virtualenv"

   Then I find the executable file path is:

   /usr/local/Cellar/python/2.7.12/Frameworks/Python.framework/Versions/2.7/bin/virtualenv

2. Touch a soft link in the /usr/local/bin/directory or add the path to .bash_profile, I prefer the former:

   sudo ln -s /usr/local/Cellar/python/2.7.12/Frameworks/Python.framework/Versions/2.7/bin/virtualenv /usr/local/bin/virtualenv
   

1. sudo find / -name "virtualenv"

   然后我发现可执行文件路径是：

   /usr/local/Cellar/python/2.7.12/Frameworks/Python.framework/Versions/2.7/bin/virtualenv

2. 触摸/usr/local/bin/目录中的软链接或将路径添加到.bash_profile，我更喜欢前者：

   sudo ln -s /usr/local/Cellar/python/2.7.12/Frameworks/Python.framework/Versions/2.7/bin/virtualenv /usr/local/bin/virtualenv

Re-installling virtualenv fixed my problem.

重新安装 virtualenv 解决了我的问题。

I had the same issue.

我遇到过同样的问题。

$ mkvirtualenv mysite
ERROR: virtualenvwrapper could not find virtualenv in your path

After a lot of time consuming efforts, I decided to re-install virtualenv.

sudo apt install virtualenv

This fixed my issues. I already had virtualenv installed. But I think it got broken or met with some errors.

1. Find where is your virtualenvwrapperlocated. in my case

1. 查找您所在的virtualenvwrapper位置。就我而言

 ~/.local/bin

May be it's installed in

可能是安装在

/usr/local/bin/

It totally depends on the System or Package Manager you are using.

这完全取决于您使用的系统或包管理器。

1. Add this path in your shell configuration .bashrcor .zshrcor whatever by simply

2. 在你的shell配置中添加这条路径.bashrc或.zshrc或任何通过简单

PATH=$PATH:<directory_you_want_to_add>

for example

例如

PATH=$PATH:~/.local/bin

Also add the following configuration in .bashrcor .zshrc

还添加以下配置.bashrc或.zshrc

# the path you want your virtual environments to be saved and loaded from
export WORKON_HOME=$HOME/.virtualenvs 
export PROJECT_HOME=$HOME/<project_folder>

# most important, this is the program which loads virtualenv
# please update the path where virtualenvwrapper.sh is located
source /usr/local/bin/virtualenvwrapper.sh 

Don't Forget to restart the shell.. or reload the configuration...

不要忘记重新启动shell .. 或重新加载配置...

To test whether it worked

测试它是否有效

mkvirtualenv test

if you see a test environment created then everything is ok.

如果您看到创建了一个测试环境，则一切正常。

The way I did it was (using zsh) in this way:

我这样做的方式是（使用 zsh）以这种方式：

export PATH=$HOME/bin:/usr/local/bin:$PATH:/Users/username/Library/Python/2.7/bin:$PATH

export PATH=$HOME/bin:/usr/local/bin:$PATH:/Users/username/Library/Python/2.7/bin:$PATH

I simply located the file of virtualenvwrapper.sh inside this path /Users/username/Library/Python/2.7/bin:$PATH

我只是在这个路径中找到了 virtualenvwrapper.sh 文件 /Users/username/Library/Python/2.7/bin:$PATH

and added that path to PATH.

并将该路径添加到 PATH。

I am using python3 with virtualenvwrapper installed on Ubuntu 18.04, using pip3 without sudo. If you are in this situation, you might find interesting my configuration.

我在 Ubuntu 18.04 上使用安装了 virtualenvwrapper 的 python3，使用没有 sudo 的 pip3。如果您处于这种情况，您可能会发现我的配置很有趣。

In the end of my .bashrc I added the following rows (remember to put your usernamein the YOUR_USERNAME field):

在我的 .bashrc 的末尾，我添加了以下行（记住将您的用户名放在 YOUR_USERNAME 字段中）：

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_VIRTUALENV=/home/YOUR_USERNAME/.local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh

Then restart the cli with ctrl-D ctrl-T or reload the config with source ~/.bashrc. Then you should be good to go! Try the installation with:

然后使用 ctrl-D ctrl-T 重新启动 cli 或使用source ~/.bashrc. 那么你应该很高兴去！尝试安装：

lsvirtualenv
mkvirtualenv test
workon test
deactivate
rmvirtualenv test

If you could create and delete a virtual environment, you are ready to go.

如果您可以创建和删除虚拟环境，那么您就可以开始了。

I had this same issues and tried many many things, what found as a solution is i had three pip version, pip with 2.7, 3.6 and 3.7. and 3.6 was the one works fine for many things, and install as sudo pip3.6 install virtualenv, and it works fine. I would suggest, check your pip version and tried to install based on your pip ver.

我遇到了同样的问题并尝试了很多东西，找到的解决方案是我有三个 pip 版本，2.7、3.6 和 3.7 的 pip。和 3.6 是一个在很多事情上都能正常工作的，并且安装为sudo pip3.6 install virtualenv，它工作正常。我建议，检查您的 pip 版本并尝试根据您的 pip 版本进行安装。

ERROR: virtualenvwrapper could not find virtualenv in your path

This error means - program virtualenvis not in your system path. This mostly happens if you install virtualenvvia pip without sudo. This kind of installation stores data in users local directory e.g ~/.local/bin. So first step is to find where this binary present. You can do that using locateprogram. First update its database using sudo updatedb. Then run locate *bin/virtualenv. Whatever path you get, append it in system path variable. This you can do by adding below line in your shell config file e.g. ~/.bashrc or ~/.zshenv.

此错误意味着 - 程序virtualenv不在您的系统路径中。如果您在virtualenv没有 sudo 的情况下通过 pip安装，则通常会发生这种情况。这种安装将数据存储在用户本地目录中e.g ~/.local/bin。所以第一步是找到这个二进制文件的位置。你可以使用locate程序来做到这一点。首先使用sudo updatedb. 然后运行locate *bin/virtualenv。无论您获得什么路径，都将其附加到系统路径变量中。这可以通过在 shell 配置文件中添加以下行来完成，例如~/.bashrc or ~/.zshenv.

export PATH=$PATH:/your/path

e.g.

例如

export PATH=$PATH:~/.local/bin

Now open new shell and try again. Error should be gone.

现在打开新外壳并重试。错误应该消失了。
