python - pylint 在 conda 环境中失败

Question

我无法在 conda 虚拟环境中获得 pylint 的基本用法。如果这还不受支持，我可以使用其他 linting 工具吗？

conda install pylint
pylint testfile.py

测试文件.py:

#!/usr/bin/env python
print("hello, world")

pylint路径:

$ which pylint
/home/me/anaconda3/envs/myenv/bin/pylint

$ conda list | grep pylint
pylint                    1.4.2                    py35_0    defaults

回溯:

此问题已在 Bitbucket 的上游得到修复，代码已渗透到 pip，但尚未渗透到 Conda。现在用 pip 安装它。

conda uninstall -y pylint
pip install --no-input pylint

[编辑] pylint 包已在 Continuum 存储库中更新，您现在可以使用 Conda 和 Python 3.5 安装 pylint 并且它可以毫无问题地运行。
