No module named 'conda'

conda 报错如下：

Traceback (most recent call last):
  File "/opt/app/conda/bin/conda", line 7, in <module>
    from conda.cli import main
ModuleNotFoundError: No module named 'conda'

查看了下 PATH，也是对的，测试了几条 conda 安装包的命令，发现在安装 lightgbm 后，才会出现这个问题：

# conda install --quiet --yes -c conda-forge lightgbm=2.2.1
...
The following packages will be DOWNGRADED:

    python:          3.7.0-hc3d631a_0                  --> 3.6.7-h357f687_1005  conda-forge
....


# conda install --quiet --yes -c conda-forge xgboost=0.80
Traceback (most recent call last):
  File "/opt/app/conda/bin/conda", line 7, in <module>
    from conda.cli import main
ModuleNotFoundError: No module named 'conda'

猜测是由于对 python 的修改引起的，真实原因暂没时间验证。
