我们目前在更新tezos节点时收到此类错误消息.

我们的升级过程如下: 1.我们将〜/tezos主目录复制到名为〜/tezos-new的新目录. 2.如下所示调用更新命令. 3.停止节点,更改目录名称,然后再次启动节点.

使用此命令:

cd〜/tezos-new＆amp;＆amp;评估$(opamenv)＆amp;＆amp;清洁＆amp;＆amp;git结帐 主网gitpull＆amp;＆amp;清洁＆amp;＆amp;制作构建＆amp;＆amp;评估$(opam env)＆amp;＆amp;制作＆amp;＆amp; cd〜

我们收到这样的错误:

任何见解都值得赞赏.

最后,节点被更新,并且正在运行最新的块和所有内容.只是想进一步了解此消息.谢谢.

We are currently receiving these kind of error messages when updating our tezos node.

Our upgrading procedure are like this: 1. We copy the main ~/tezos directory to a new directory called ~/tezos-new. 2. Call update command as shown below. 3. Stop node, change directory names, and start node again.

Using this command:

cd ~/tezos-new && eval $(opam env) && make clean && git checkout mainnet && git pull && make clean && make build-deps && eval $(opam env) && make && cd ~

We get errors like this:

[ERROR] No switch is currently set. Please use 'opam switch' to set or install a switch

Any insight is much appreciated.

In the end the node is updated, and is running latest block and everything. Just wanted to get more insight into this message. Thanks.
