pip freeze命令提供了以下已安装模块的列表：

cffi==1.13.2
cryptography==2.8
dj-database-url==0.5.0
Django==2.2.7
django-extensions==2.2.5
django-filter==2.2.0
django-secure==1.0.1
django-sslserver==0.22
djangorestframework==3.10.3
ez-setup==0.9
Pillow==6.2.1
pkg-resources==0.0.0
pycparser==2.19
pyOpenSSL==19.1.0
pytz==2019.3
six==1.13.0
sqlparse==0.3.0

moviepy模块不在列表中。为什么？

安装moviepy时，您使用的是sudo，它以root用户身份安装软件包，这就是为什么pip在/usr/local/lib/python2.7/dist-packages文件夹中搜索

激活环境env后，不要使用sudo安装moviepy，软件包将安装在您的env中。

使用sudo作为pip安装的前缀，您可以在另一个环境中运行安装，因此基本上不需要安装软件包

因此，您应该在以下情况下运行此操作：

(env)$: pip install moviepy

注意：安装软件包时请不要使用sudo。用sudo运行它 您授予安装根用户访问权限。如果包中有恶意代码， 您可以给它更改系统的可能性。你可以用 pip3安装-改为用户packagename

您是否使用虚拟环境？安装软件包时请不要使用sudo，这是一个安全漏洞，请使用-user标志。是的，我使用的是虚拟环境。django项目的所有安装都发生在一个虚拟环境中。如果您在另一个shell中运行sudo，那么虚拟环境将不再激活。无论如何，不要使用sudo。sudo-ing将退出您的VirtualNV

(env)$: pip install moviepy
