passlib未在python中导入

Question

当我尝试导入passlib时，出现以下错误。在

ImportError: No module named passlib.apps

我试图通过以下命令安装它，他们声称它成功或已经存在，但我的程序仍然拒绝导入它：

pip安装密码库

sudo pip安装passlib

apt get安装python pip pip安装密码库

以下是我如何构建我的环境： 我导航到文档/45 我运行命令：source env/bin/activate
然后我运行pip install passlib，它告诉我： 已满足要求：./env/lib/python2.7/site-packages中的passlib

然后我打字/跑.py在

这是我的密码 运行.py在

不过，这对我有效，所以问题可能出在你的环境中。在

-我使用的是python2.7并安装了（通过pip）passlib-1.7.1。-

我没有意识到我是从flask/bin运行环境，所以运行以下命令修复了它

flask/bin/pip install passlib
