如何在yaml中正确转义&&

Question

我正在尝试运行我的 gitlab 管道中的以下行：

[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

我在 Ubuntu 终端中测试了命令，它在那里工作正常。

我在我的 gitlab-ci.yml 文件中尝试了以下行但没有成功：

script:
  - "[ -s \"$NVM_DIR/nvm.sh\" ] && \. \"$NVM_DIR/nvm.sh\""   # escaping the full line with double quotation marks and then only escaping the quotation marks inside the line -> is marked as invalid yml by gitlab: " found unknown escape character while parsing a quoted scalar"
  - \[ -s \"$NVM_DIR/nvm.sh\" ] &amp;&amp; \. \"$NVM_DIR/nvm.sh\"   # escaping each special character and replacing the ampersands with &amp; -> fails with: syntax error: unexpected "&"
  - "[ -s \"$NVM_DIR/nvm.sh\" ] &amp;&amp; \. \"$NVM_DIR/nvm.sh\""  # this was marked as invalid yml syntax by gitlab ("found unknown escape character while parsing a quoted scalar")

阅读 Biffen 的评论后，以下行有效：

- "[ -s \"$NVM_DIR/nvm.sh\" ] && . \"$NVM_DIR/nvm.sh\""

所以问题出在转义上。不再需要转义，因为我将命令用双引号引起来。
