分析是package版本解析时遇到了问题了
解决方法：
将这个路径下的 handlers.py 代码进行修改，各人的安装路径不同，对照自己的路径找一下
D:\Miniconda\pkgs\nb_conda-2.2.1-py38_1\Lib\site-packages\nb_conda\handlers.py
修改前
for entries in data.values():
max_version = None
max_version_entry = None
for entry in entries:
version = parse_version(entry.get('version', ''))
if max_version is None or version > max_version:
max_version = version
max_version_entry = entry
packages.append(max_version_entry)
return sorted(packages, key=lambda entry: entry.get('name'))
修改后
for entries in data.values():
max_version = None
max_version_entry = None
for entry in entries:
try:
version = parse_version(entry.get('version', ''))
except Exception as e:
# print(entry.get('name'))
continue
if max_version is None or version > max_version:
max_version = version
max_version_entry = entry
if max_version_entry:
packages.append(max_version_entry)
return sorted(packages, key=lambda entry: entry.get('name'))
经过测试，成功解决问题
