skopt下载

在pycharm中直接下载skopt时失败，网上有如下解决办法：
在python当前位置执行下载，
1.先安装scikit-optimize

pip install scikit-optimize
1

后直接在pycharm中安装skopt成功
若不成功，
2.安装

git clone https://bitbucket.org/stanmarkov/skopt/
1

转到skopt目录，执行

pip3 install --upgrade --user -r requirements.txt -e .

requirements.txt文件用于记录依赖包和版本号，安装其依赖包。若报错，Could not find a version that satisfies the requirement deap (from versions: none) ，执行

pip install deap  -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
1

安装缺失的内容，
pip3 install --upgrade --user -r requirements.txt -e .执行若报错，Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘ProxyError(‘Cannot connect to proxy.’, OSError(0, ‘Error’))’: /simple/matplotlib/</
