Question

我的项目中有一个测试，涉及打开和读取文件。代码块基本上是这样的：

import pandas as pd

with open('path/to/the/file') as file:
  df = pd.read_csv(file, comment='#')

在PyCharm中运行测试时，出现此错误：

  File "/Users/andrea.marchini/.local/share/virtualenvs/customer-ontology-OqrlJ3HG/lib/python3.5/site-packages/pandas/io/parsers.py", line 655, in parser_f
    return _read(filepath_or_buffer, kwds)

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 202538: ordinal not in range(128)

无论如何，如果我从python控制台运行相同的代码，一切都会很好。

将此行添加到.bash_profile文件中即可解决此问题

if [ -z "$LANG" ]; then export LANG="$(defaults read -g AppleLocale | sed 's/@.*$//g').UTF-8"; fi

在PyCharm中运行测试时出现UnicodeDecodeError
