我想在运行Python 3.7的Ubuntu 18.04 VPS上安装Pillow
软件包。我首先创建了一个虚拟环境-
python -m venv /path/to/env
source /path/to/env/bin/activate
我从那里尝试通过运行Pillow
安装pip install Pillow
,但发生以下异常:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-install-0c7eruo4/Pillow/setup.py", line 806, in <module>
raise RequiredDependencyException(msg)
__main__.RequiredDependencyException:
The headers or library files could not be found for zlib,
a required dependency when compiling Pillow from source.
Please see the install instructions at:
https://pillow.readthedocs.io/en/latest/installation.html
根据this回答,需要安装软件包libjpeg8-dev
,但是Ubuntu告诉我它已经已安装,所以我不知道发生了什么。 (为了安全起见,我还验证了安装了非开发版本libjpeg8
的安全性)在简单地设置Python开发环境之前,我没有遇到这么多错误-有人可以建议吗?
