我正在关注有关在 Windows 7 上使用数据版本控制的教程。mingw32
当我尝试使用run时，我遇到了非常奇怪的错误：
$ dvc run -v echo "hello"
Debug: updater is not old enough to check for updates
Debug: PRAGMA user_version;
Debug: fetched: [(2,)]
Debug: CREATE TABLE IF NOT EXISTS state (inode INTEGER PRIMARY KEY, mtime TEXT NOT NULL, md5 TEXT NOT NULL, timestamp TEXT NOT NULL)
Debug: CREATE TABLE IF NOT EXISTS state_info (count INTEGER)
Debug: CREATE TABLE IF NOT EXISTS link_state (path TEXT PRIMARY KEY, inode INTEGER NOT NULL, mtime TEXT NOT NULL)
Debug: INSERT OR IGNORE INTO state_info (count) SELECT 0 WHERE NOT EXISTS (SELECT * FROM state_info)
Debug: PRAGMA user_version = 2;
Running command:
echo hello
/c: /c: Is a directory
Debug: SELECT count from state_info WHERE rowid=1
Debug: fetched: [(1,)]
Debug: UPDATE state_info SET count = 1 WHERE rowid = 1
Error: Traceback (most recent call last):
File "dvc\command\run.py", line 18, in run
File "dvc\project.py", line 265, in run
File "dvc\stage.py", line 435, in run
StageCmdFailedError: Stage 'Dvcfile' cmd echo hello failed
Error: Failed to run command: Stage 'Dvcfile' cmd echo hello failed
问题：
从哪里来/c: /c: Is a directory？我该如何解决？
我的发现
我认为它正在解析回声的路径，但 ech 是内置的。
$ type echo echo is a shell builtin我也尝试过
exit，cd但我遇到了同样的错误。在没有 dvc 的情况下调用命令可以正常工作。
dvcwith--no-exec标志可以正常工作，但是稍后执行 with 时repro会出现相同的错误。
