当我尝试安装django-extensions时，我正在尝试理解为什么会出现这个问题。然而，我在virtualenv (包装器) goat中，但它不想安装在其中。我该怎么解决这个问题呢？

更新

在virtualenv上使用ls -ld，我得到了

drwxrwxr-x 7 jeremie jeremie 4096 Sep  9 17:10 goat

Answer 1

如果您以root身份创建了您的virtualenv，则可能会出现此问题。

如果是这样，您可以运行以下命令来修复它：

sudo chown -R your_username:your_username path/to/virtuaelenv/

更新

发生这种情况的另一个原因是您已经将pip (或本例中的pip3 )安装为根目录。

从您的错误中，您可以看到它正在尝试将包安装到您的virtualenv之外的根级别。

要验证这一点，请检查pip安装的权限：

user@host:~$ which pip3 
/usr/local/bin/pip3
user@host:~$ ls -l /usr/local/bin/pip3
-rwxr-xr-x 1 root root ... etc, etc

或者只运行一行代码：

ls -l `which pip3`

您可以通过卸载pip3并在不使用sudo命令的情况下重新安装它来修复此问题。

Answer 2

你不需要在virtualenv中使用'pip3‘。

所以只需使用：

  pip install django-extensions

激活虚拟环境后
