我将创建自己的Django Web应用程序，但我无法准备虚拟环境并安装Python包。当我在终端中执行$ virtualenv时，我收到错误：

Traceback (most recent call last):
  File "/usr/bin/virtualenv", line 6, in <module>
    from pkg_resources import load_entry_point

    if len(os.listdir(path)) == 0:
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.6/dist-packages/pytz-2017.3.dist-info'

$ pip命令的结果：

Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 21, in <module>

和$ pip3命令：

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ModuleNotFoundError: No module named 'pip._vendor.pkg_resources'

During handling of the above exception, another exception occurred:

以root身份运行的

virtualenv，pip，pip3似乎正在运行。我正在进行Debian 9测试。

任何人都可以帮助我吗？

请勿使用{ "_id": "59f372389f89d1cb0dbabdbad", "residence": "Katowice, Poland", "orientation": "Bisexual", "lastName": "Kowalczyk", "job": "Web Developer @ Freelance", "gender": "Female", "firstName": "Marina", "dob": "7/10/1998", "about": "Computer science student", "lastConnection": "2017-11-24T19:16:28.780Z", "created_at": "2017-10-27T20:55:06.070Z", "phone": { "number": "7183173136" }, "profilePicture": { "url": "https://.JPG", "pictureType": ".JPG" }, "interests": [ "Sports", "Food", "Cycling", "Running", "Cooking", "Movies", "Fashion", "Business", "Travel", "Music", "Theatre", "Yoga", "Party", "Dancing", "Reading" ], "__v": 38} 。你真的不需要它。

以下是如何在虚拟环境中使用Django（强烈推荐）。

  • 选择要安装Web应用程序的目录。我们称之为{ "_id": "59a83258c7fd5b4ae586c53b", "visibilityLocation": true, "visibilityGenderPreferences": true, "visibilityFb": false, "visibilityDistance": false, "visibilityAge": false, "showMyProfileAs": "Male", "showMe": "Males", "locationAccuracy": 0, "accountId": "59f372389f89d1cb0dbabdbad", "created_at": "2017-08-31T13:29:42.462Z", "distance": { "max": 30, "metrics": "K", "min": 0 }, "ageRange": { "max": 32, "min": 18 }, "__v": 0} ：root
  • 创建虚拟环境：myproj
  • 激活虚拟环境：mkdir myproj && cd myproj
  • 安装包：python -mvenv venv

你很高兴。

请记住每次需要使用此项目时都要激活虚拟环境。 也就是说，每次打开一个新的shell来使用这个项目时， . venv/bin/activate pip install django再次使用cd再次运行激活脚本。 虚拟环境在当前shell中保持活动状态， 所以你不需要在每次操作之前重新运行， 你只需要在每个新shell中运行一次。
