Question

当我尝试导入passlib时出现以下错误。

ImportError: No module named passlib.apps

我试图通过以下命令安装它来安装它并声称它已成功或已经存在但我的程序仍然拒绝导入它：

pip install passlib

sudo pip install passlib

apt-get install python-pip pip install passlib

以下是我构建环境的方法：我导航到Documents / 45 我运行命令：source env / bin / activate
然后我运行pip install passlib，它告诉我：要求已经满足：passlib in ./env/lib/python2.7/site-packages

然后我输入./run.py

(env) jsnyder10@jsnyder10-VirtualBox:~/Documents/45$ ./run.py
Traceback (most recent call last):

Answer 1

但它对我有用，所以问题可能在你的环境中。

- 我正在使用Python 2.7并安装（通过pip）passlib-1.7.1 .-

我没有意识到我正在从flask / bin中运行环境，因此运行以下命令修复它

flask/bin/pip install passlib

passlib不在python中导入
