[英]It shows “ [Errno 13] Permission denied: '/usr/lib/python2.7/dist-packages/Jinja2-2.8.egg-info/entry_points.txt'” when trying to install flask?
问题描述
I've tried to install on terminal and I've used two commands: 
我试过在终端上安装，我使用了两个命令：
-
pip install flask -
pip install -U flask
It shows the same error message on both cases: 它在两种情况下都显示相同的错误消息：
I've tried pip install -U flask but that shows the same error. 我试过pip install -U flask但是显示了同样的错误。
Here is the error I'm getting: 这是我得到的错误：
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Best way is probably to use pip install <libname> --user 最好的方法可能是使用pip install <libname> --user
Meaning in your case use pip install flask --user 在您的情况下使用pip install flask --user
This installs the package for your user and that is safe. 这将为您的用户安装包，这是安全的。 Also you have probably the right of installing the package for the user. 您也可能有权为用户安装软件包。
The permission error you have encountered is a frequent problem. 您遇到的权限错误是一个常见问题。 As can be seen here: pip is not able to install packages correctly: Permission denied error and here error: could not create '/usr/local/lib/python2.7/dist-packages/virtualenv_support': Permission denied 从这里可以看出： pip无法正确安装包：权限被拒绝错误 ，此处错误：无法创建'/usr/local/lib/python2.7/dist-packages/virtualenv_support'：权限被拒绝
Using the sudo pip command is not considered as safe as explained here: What are the risks of running 'sudo pip'? 使用sudo pip命令并不像这里解释的那样安全： 运行'sudo pip'有什么风险？
