根因分析
约束文件必须包含带有版本说明符的包名（例如 package1>=1.0），但发现了一个裸包名。
English
A constraint file must contain package names with version specifiers (e.g., package1>=1.0), but a bare package name was found.
解决方案
-
95% 成功率
echo 'package1>=1.0' >> constraints.txt
-
90% 成功率
sed -i '/^package1$/d' constraints.txt
无效尝试
常见但无效的做法:
-
100% 失败
Comments are ignored; the invalid line still causes error.
-
60% 失败
Constraints files have different syntax; using them as requirements may fail.
