在PyCharm下的Terminal运行文件或者模块。出现了错误:ModuleNotFoundError: No module named ‘src’
sys.path.insert(0, ‘…/’)
import sys, os
sys.path.insert(0, '../')
from setup import LOGFILE, NOW
from src.model import health_index
if __name__ == '__main__':
print("Start at ", NOW, ", 输入内容为:", sys.argv)
LOGFILE.info(sys.argv)
for arg in sys.argv:
print("", arg)
在PyCharm下的Terminal下运行及结果如下:
(eehi366) D:\programs\Anaconda_program\eehi\src>python main.py 1,2,3 a.out
file_name = log/eehi.log
Start at 2020-12-04 15:46:31.101098 , 输入内容为: ['main.py', '1,2,3', 'a.out']
main.py
1,2,3
a.out
sys.path.insert(0,"/path") 的用法
注意:此时没有sys.path.insert(0, ‘…/’)行代码
(eehi366) D:\programs\Anaconda_program\eehi>python -m src.main 202010 test_out
file_name = log/eehi.log

python -m 参数释义
Python3.6 error: ModuleNotFoundError: No module named ‘src’
在alg环境下,import其他文件报错:ModuleNotFoundError: No module named ‘src’。信息如下。
from src.evaluate_metrics import EvaluateMetrics
from alg.algorithm.Algorithm import Algorithm
File "D:\programs\Anaconda_program\do_time_series_product\src\time_series_ma.py", line 19, in <module>
from src.evaluate_metrics import EvaluateMetrics
ModuleNotFoundError: No module named 'src'
尝试过下面的3种,没有解决。
curPath = os.path.abspath(os.path.dirname(file))
rootPath = os.path.split(curPath)[0]
sys.path.append(rootPath)
sys.path.append(curPath)
改成下面的就解决了,顺序不能颠倒。其含义是:把当前文件所在文件夹的父文件夹路径加入到PYTHONPATH。
先把文件路径追加到系统变量中,再导入包。顺序不可颠倒。
sys.path.append(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
from src.evaluate_metrics import EvaluateMetrics
# 或者
curPath = os.path.abspath(os.path.dirname(__file__))
rootPath = os.path.split(curPath)[0]
sys.path.append(rootPath)
from src.evaluate_metrics import EvaluateMetrics
