python3安装时出现的问题

已有 8713 次阅读 2021-2-22 17:07 |系统分类:科研笔记

python3安装时,make install时经常会出现这样的错误:

subprocess.CalledProcessError: Command ‘(‘lsb_release’, ‘-a’)’ returned non-zero exit status 1.

其解决方法方法如下:
find / -name lsb_release
rm -rf /usr/bin/lsb_release

重新编译make install即可。


根据以下链接可以成功安装python3.6.8。

pip3安装numpy时(pip3 install numpy)出现如下错误:

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting numpy

解决办法:

sudo pip3 install selectivesearch -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

即可解决。
