ModuleNotFoundError:在pipenv中没有名为“dlib”的模块
提问于 2020-01-31 11:53:09
对不起，我对这一切都是新手。我无法在pipenv虚拟环境中安装dlib，但是，我能够在pipenv虚拟env之外安装和导入它。
当我导航到包含我的代码的文件夹并键入pipenv shell，然后键入python3 example.py (这是我想要运行的代码)时，我会得到以下错误：
import dlib
ModuleNotFoundError: No module named 'dlib'然后，我尝试使用以下命令安装dlib：
$ sudo apt-get update
$ sudo apt-get install build-essential cmake
$ sudo apt-get install libopenblas-dev liblapack-dev
$ sudo apt-get install libx11-dev libgtk-3-dev
$ sudo apt-get install python python-dev python-pip
$ sudo apt-get install python3 python3-dev python3-pip
$ pip3 install dlib除了最后一个命令之外，所有操作都很好，这是我得到的红色输出：
$ pip3 install dlib

我没有主意了，非常感谢你的建议。

我尝试使用conda在pipenv虚拟环境中安装dlib，结果如下：

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- dlib -> python[version='2.7.*|3.5.*|>=3.5,<3.6.0a0']
- dlib -> python[version='>=2.7,<2.8.0a0']
Your python: python=3.7
If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.
The following specifications were found to be incompatible with each other:
Package certifi conflicts for:
python=3.7 -> pip -> setuptools -> certifi[version='>=2016.09|>=2016.9.26']
dlib -> python=3.5 -> pip -> setuptools -> certifi[version='>=2016.09|>=2016.9.26']
Package wheel conflicts for:
dlib -> python=3.5 -> pip -> wheel

Package setuptools conflicts for:
python=3.7 -> pip -> setuptools

我确保pipenv使用python3.5(正如您在上面的pip3错误中看到的那样)，但我仍然不能通过pip3或conda安装dlib。奇怪的是，conda错误告诉我Your python: python=3.7，而pip3错误清楚地声明我使用python3.5：Building extension for Python 3.5.9
请指点。

尝试以下几点：
conda create --name python3_5 python=3.5
conda activate python3_5
conda install -c menpo dlib页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
