I'm testing the following snippet:
entry := 'notes.txt' asFileReference.
writer := entry writeStream.
writer nextPutAll: 'hello world'.
writer close.
entry content.Instead this exception appears:
**FileDoesNotExistException**Writing a text file with smalltalk

Elin Permalink 'notes.txt' asFileReference writeStreamDo: [ :sink | sink << 'Hello, World!' ].That ought to succeed. However, it expresses your earlier approach differently, which makes me suspect incorrect write permissions or a related issue somewhere in the environment.
tobin Permalink Adding something to Elain's reply, an unexpected detail in Pharo is how writeStreamDo writes over a file, leaving a combination of the replacement contents and the previous contents' ending whenever the old file contains more data than its replacement. Luckily, fixing this is straightforward: just add truncate to the block. Here is a somewhat more "safe" alternative:
'notes.txt' asFileReference writeStreamDo: [ :sink | sink truncate. sink << 'Hello, World!' ].
