I unzipped the current nodejs to / opt/app/node-v8.11.4-linux-x64
-sharp
ln -s /opt/app/node-v8.11.4-linux-x64/bin/node /usr/local/bin/has no effect on executing node-v,
(not even using ln-s / opt/app/node-v8.11.4-linux-x64/bin/node / usr/local/bin/node)
root user path does not have / usr/local/, of course, cannot be found. To execute directly in the bin directory, you must add. / / p >
/ usr/local/bin/ does not exist in the root $PATH environment variable.
Next: Angular6 httpclient has already assigned a value to the field, why does the field always undefined?
