Question

在Arch Linux上，我收到此错误，没有名为'scipy.stats'的模块

但是已安装此模块：

我尝试以两种不同的方式安装它：

pip3 install scipy

和

sudo pacman -S python-scipy

如何强制它在此位置查找模块？（/ usr / lib / python3.7 / site-packages / scipy / stats /）

Answer 1

用sys.path.insert（see here）指定要查看的位置。

import sys
sys.path.insert(0, <your-location>)

它应该找到它！

Answer 2

我解析日志（由命令python3.7 -v -c "import scipy.stats" 2> log.txt产生），发现它在$ HOME / .local / lib / python3.7 / site-packages / scipy / stats中搜索统计信息，但是统计信息不存在从那里删除scipy目录，所有工作。如果通过带有--user标志的pip安装，它将安装到$ HOME / .local / python3.7 / site-packages /

没有名为“ scipy.stats”的模块，但已安装
