尽管成功地安装了python3-venv和python3.8-venv，但仍未找到Ensurepip。

Question

尽管正确地安装了所需的dev库和venv，但我还是得到了这些连续错误。

这是终端中的连续输出。

~/Desktop/virtualenvs$ python3.8 -m venv newpy38
The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt-get install python3-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

Failing command: ['/home/dji/Desktop/virtualenvs/newpy38/bin/python3.8', '-Im', 'ensurepip', '--upgrade', '--default-pip']

当我运行sudo时，要确定我已经安装了venv库。

~/Desktop/virtualenvs$ sudo apt-get install python3-venv

python3-venv is already the newest version (3.6.7-1~18.04).

当我运行sudo时，再次确定我安装了venv库。

~/Desktop/virtualenvs$ sudo apt-get install python3.8-venv
Reading package lists... Done

python3.8-venv is already the newest version (3.8.0-3~18.04.1).

我也尝试了以下链接，但没有结果：

1. python3.8-venv not working with python3.8 -m venv env
2. pyvenv not working because ensurepip is not available
3. I也用"sudo reconfigure“对地区进行了重新审查，就像在https://askubuntu.com/questions/33025/locale-settings-are-not-right-how-can-i-reset-them中一样。但这可能与此无关。--

===更新===在某种程度上，卸载和重新安装===解决了这个venv问题。我也不知道为什么。

原来这是因为一个坏了的蟒蛇安装！由于sudo apt-get update sudo apt-get autoremove的使用很差(而且不小心)，我最终导致python安装中断，无法正确找到其已安装的库。

我重新安装了python，现在可以了。

额外注意:由于我在嵌入式计算机(dji manifold2g)上使用这个选项，一些用户可能无法轻松地重新安装python。重新刷新整个固件(它与python一起预装)实际上可能会更有帮助，尽管更不方便。
