Golang sets the small details of goproxy proxy proxy, which is applicable to go module download timeout and Alibaba cloud image go module download timeout

problem

A few days ago, I was curious to add an official community group of domestic alliance chain blockchain , Then someone compiles a tool go module Download has timed out , Then I used Alibaba cloud's image , The command looks ok as follows , But still timeout .

verification

But I clean up here module cache , Verify that the Alibaba cloud image is indeed hung , But it is normal to change other mirror agents , That's ridiculous .

Analyze the causes and solutions

Then the reason must be the configuration problem , So I checked the man's bash command , There is a problem , as follows ：

Be reasonable export The command is always valid when the terminal is not turned off , But he has another detail here. I don't know if you have found it , He abused it sudo command , He compiled the command with sudo make, however root What the user is looking for golang Environment variables have not been modified , So the last one export The command is input in vain .
It's also easy to solve , Directly use the following command to modify go env environment variable

go env -w GO111MODULE=on #-w  Indicates to modify the default value of the environment variable 

go env -w GOPROXY=https://goproxy.io,direct

Use... After modification go env Check whether the order has been changed , Last make Get it done .

I have to say that it's really cool to pretend to be forced ：)
