我刚刚登录到我的笔记本电脑。, music, videos, pictures,public和来自我downloads的笔记本电脑背景。原始文件仍在工作。我对我的视频进行了试用并在我的笔记本电脑上删除并说找不到目录。然后我从垃圾箱中恢复了它。它又开始工作了。所以我意识到复制它们已经结束了。你如何删除它们？我的笔记本电脑背景看起来很混乱。我检查过：再次：fileshomegedit ~/.config/user-dirs.dirs

XDG_DESKTOP_DIR="$HOME/Desktop"
XDG_DOWNLOAD_DIR="$HOME/Downloads"
XDG_TEMPLATES_DIR="$HOME/Templates"
XDG_PUBLICSHARE_DIR="$HOME/Public"
XDG_DOCUMENTS_DIR="$HOME/Documents"
XDG_MUSIC_DIR="$HOME/Music"
XDG_PICTURES_DIR="$HOME/Pictures"
XDG_VIDEOS_DIR="$HOME/Videos"

没有什么不寻常的。

当输入virtualenvthiscmd时：

running virtualenv with interpreter /usr/bin/python2

您如何将解释器更改为最新版本python3？

virtualenv -p python3 ...

Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /home/name/.../bin/python3
Not overwriting existing python script /home/name/.../bin/python (you must use /home/name/.../bin/python3)
Installing setuptools, pkg_resources, pip, wheel...done.

我知道virtualenvandvirtualenvwrapper代表.py. python当我跑virtualenv进来PyCharm IDE时：

Usage: virtualenv.py

我最近才遇到这个并尝试搜索它，但我找不到它。virtualenv.py与仅 tovirtualenv和相比，它到底是什么，有什么不同virtualwrapper吗？这两个软件我都没有pip3安装。

我python3.7 paths的已损坏。当我最终安装apt和pip3 packages,来自virtualenv, wrapper, django. 从pip3. 我没有正确备份文件。它最终导致了venv directory和 on的问题PyCharm IDE。我尝试卸载第三个版本，virtualenv并django.没有什么不同。

所以基本上恢复Python3.7到原来的状态，不extra packages installed etc. Terminal:

python3

>>> import sys
>>> sys.path
['', '/usr/lib/python37.zip', '/usr/lib/python3.7', '/usr/lib/python3.7/lib-dynload', '/home/name/.local/lib/python3.7/site-packages', '
/usr/local/lib/python3.7/dist-packages', '/usr/lib/python3/dist-packages']

我PyCharm IDE不会自动创建一个venv directory，所以我必须手动创建我自己的。我的venv directory出现被忽略了。这个是正常的。在评论部分找到了一个可能的解决方案。创建PyCharm Project Django并virtualenv安装时。我不必安装Django. 所以现在Python3需要清理。

更新：我已经有PyCharm IDE一段时间了，我想确定是sys.path：来自PyCharm IDE terminal：

>>> python3
>>> import sys
>>> print(sys.path)
    ['', '/usr/lib/python37.zip', '/usr/lib/python3.7', '/usr/lib/python3.7/lib-dynload', '/home/name/Projects/bye/venv/lib/python3.7/site-packages', '/home/name/Projects
/bye/venv/lib/python3.7/site-packages/setuptools-40.8.0-py3.7.egg', '/home/name/Projects/bye/venv/lib/python3.7/site-packages/pip-19.0.3-py3.7.egg']

尽管创建了目录，但我仍然得到这个结果：

 ImportError(
                "Couldn't import Django. Are you sure it's installed and "
                "available on your PYTHONPATH environment variable? Did you "
                "forget to activate a virtual environment?"

ImportError 由以下 Python 3 代码的第 6 行生成，不一定由代码生成，而是由第from django.core.management import4 行生成。

我卸载了Virtualenv 16.6.0。我正在PyCharm使用virtualenv version 15.1.0. 更新：尝试/venv在创建项目中创建，但消息是这个，现在venv directory是黄色的。当我输入时，virtualenv我得到：

Running virtualenv with interpreter /usr/bin/python2
You must provide a DEST_DIR
Usage: virtualenv.py [OPTIONS] DEST_DIR

其他一切都运行Python 3.7

python3-virtualenv is already the newest version (15.1.0+ds-2).
python3-virtualenv set to manually installed.

更新：尝试了这两个命令

ImportError("Couldn't import Django. Are you sure it's installed and "
"available on your PYTHONPATH environment variable? `Did you "`
"forget to activate a virtual environment?"

) from exc

更新：我跑virtualenv cmd进来Pycharm Pro terminal 了：

You must provide a DEST_DIR
Usage: virtualenv [OPTIONS] DEST_DIR

安装并virtualenv安装。

我严重损坏了我的包裹系统。所以我找到了另一个解决方案， sudo apt-get build-dep <package>

但是当我输入时sudo apt-get build-dep update-manager，我得到了，

E: You must put some 'source' URIs in your sources.list

然后我使用sudo nano /etc/apt/sources.list. 清单是空白的。现在我不确定如何添加更多源 URI。我无法访问软件更新程序来更改它。我试过 Synaptic 包管理器。

sudo apt-get -f install   
Reading package lists...  Done  
Building dependency tree                                                                             
Reading state information... Done  
E: The package python3 needs to be reinstalled, but I can't find an archive for it.

更新：

我已经使用@karel 对 Cat /etc/apt/sources.list 的正确输出是什么的回答编辑了 sources.list？并替换bionic为cosmic.

现在，当我尝试启动时software-properties-gtk，我得到：

bash: /usr/bin/software-properties-gtk: /usr/bin/python3: bad interpreter: Too many levels of symbolic links

python3符号链接的输出：

$ ls -l /usr/bin/python3
