Question

在Circle CI上运行我的测试以获得干净生成的Phoenix项目时，我得到：

** (Mix) Could not find migrations directory "priv/repo/migrations"
for repo Martinffx.Repo.

This may be because you are in a new project and the
migration directory has not been created yet. Creating an
empty directory at the path above will fix this error.

If you expected existing migrations to be found, please
make sure your repository has been properly configured
and the configured path exists.

但在本地运行相同的命令时，它会成功运行：

$ mix test
....

Finished in 0.1 seconds
4 tests, 0 failures

Randomized with seed 328700

为什么呢？我没有迁移吗？它在本地工作......发生了什么？

git不存储不包含任何文件本身或任何子目录的目录。由于您的迁移目录没有任何迁移，即使您将整个应用程序添加并提交到git中，当您将git repo克隆到另一个目录时，您也会发现priv/repo/migrations目录不存在。 Ecto要求存在此目录，这就是您收到错误的原因。

为了让git创建priv/repo/migrations，您可以在priv/repo/migrations内创建并提交一个虚拟文件。您还可以将以下行添加到预构建shell文件（mix compile之前）以创建该目录（如果它不存在）：

mkdir -p priv/repo/migrations

凤凰城：**（混合）无法找到迁移目录＆＃34; priv / repo / migrations＆＃34;
